These gas emissions are believed to fuel the process of star formation in galaxies but are not yet well understood. Astronomers are interested in learning more about them to improve our understanding of what governs galactic evolution.

This is the purpose of the SUper massive Black hole Winds in the x-rAYS (SUBWAYS) project, an international research effort dedicated to studying quasars using the ESA's XMM-Newton space telescope.

The first results of this project were shared by a group of scholars led by the University of Bologna and the National Institute for Astrophysics (INAF) in Italy. In the paper that describes their findings, the team presented X-ray spectroscopic data to characterize the properties of UFOs in 22 luminous galaxies.

Most powerful cosmological beast discovered

A newly discovered quasar - J0529-4351 - holds at its heart the universe's fastest-growing black hole. It weighs in at a mass of 17 billion Suns - bigger than many entire galaxies - and it eats more than a star's mass each day.

This quasar is also the most luminous object in the known universe. The matter this black hole consumes collects in the form of an accretion disc that emits so much energy that J0529-4351 shines 500 trillion times brighter than the Sun - thousands of times brighter than our whole galaxy.

This hot accretion disc stretches seven light-years in diameter - the largest in the universe, about 15,000 times the width of our whole Solar System.

J0529-4351 is so far away that its light took over 12 billion years to reach our telescopes, making it one of the earliest quasars.

More info at the European Southern Observatory website: X

Writers: If you're looking for a space-opera setting that blows everything else away - or a source of cosmological horror - you need look no further than quasar J0529-4351.

Gamma-Ray Quasars - October 23rd, 1995.

"Gamma rays are more than 10,000 times more energetic than visible light. If you could "see" gamma rays, the night sky would seem very different. The bright object in the center of the false colour gamma-ray image above is quasar 3C279, a nondescript, faint, star-like object in the visible sky. Yet, in June of 1991, a gamma-ray telescope onboard NASA's orbiting Compton Gamma Ray Observatory unexpectedly discovered that it was one of the brightest objects in the gamma-ray sky. Shortly after this image was recorded, the quasar faded from view at gamma-ray energies. Astronomers are trying to understand what causes these enigmatic objects to flare so violently. Another quasar, 3C273, is faintly visible above and to the right of the center."

Webb Telescope Captures Images of Quasar Host Galaxies in Early Universe. Read full article here

June 28, 2023 - In a groundbreaking discovery, scientists utilizing the James Webb Space Telescope (JWST) have successfully captured images of starlight from two massive galaxies hosting actively growing black holes, known as quasars. These images reveal the earliest epoch to date in which light from stars has been detected around a quasar, less than a billion years after the Big Bang. The findings shed light on the formation of black holes and their relationship with host galaxies in the early universe.

The Study and Findings:

Led by researchers from the Kavli Institute for the Physics and Mathematics of the Universe and the Peking University Kavli Institute for Astronomy and Astrophysics, the study utilized a combination of ground-based observations from the Subaru Telescope and space-based observations from the JWST. The team focused on two quasars, HSC J2236+0032 and HSC J2255+0251, which were discovered through Subaru Telescope's deep survey program. These quasars, located when the universe was around 860 million years old, provided an opportunity to study the properties of their host galaxies. Read full article here.

I two things:

1, I love any and all of yet rambles, especially the space ones. Space is also one of my special interests, and it makes me so so so so happy whenever I see something about it on one of my favorite blogs!

If my brain wasn’t so stupid and actually let me remember stuff when I want to, perhaps I’d actually be able to keep all I learn >:(

2, Please remember to drink some water, eat some food even if it’s just a few crackers, and rest.

Ya can use this ask as an excuse to talk about space ^^

1. I AM CONSIDERED ONE OF YOUR FAVOURITE BLOGS? *falls from my gaming chair*

Thank you.

Astrophysics is a wonderful field of science.

Don't worry, I don't have the memory of an elephant, so I can't keep everything in mind. It's not bad to forget stuff. I like to reread & rewatch stuff & I feel happy when I read or see stuff that I already know. It's like: WHOOP, THAT I KNOW!

2. ... You got me there. When I'm in hyperfocus, it's really hard to remember to eat or drink. Sometimes, I don't even want to. A few minutes of nourishing my body feel like eternity even though I know that is JUST my emotional perception.

Oooooh, another infodump about space? Hehe...

You won't regret this, will you?

✨️Let's talk quasars! ✨️

'Quasar' is short for 'quasi-stellar radio source'.

Quasars got that name because they looked starlike when astronomers first discovered them in the earliest radio surveys of the sky in the 1950s.

Some of the radio sources discovered back then coincided with objects that appeared to be unusually blue stars, although photographs of some of these objects showed them to be embedded in faint, fuzzy halos.

But quasars aren’t stars.

They are, in fact, young galaxies located at vast distances from us, with their numbers increasing towards the edge of the visible universe.

The oldest quasar, currently, is J0313-1806. Its distance is approximately 13.03 billion light-years, & therefore, we see it as it was just 670 million years after the Big Bang.

Quasars are extremely bright, up to 1,000 times brighter than our Milky Way. We know that they’re highly active, emitting staggering amounts of radiation across the entire electromagnetic spectrum.

A quasar is a type of an 'active galactic nucleus', short AGN.

(There are actually many different types of AGNs, each with their own tale to tell.)

Theoretically, the intense radiation released by an AGN powers a supermassive black hole.

The powerful radiation comes from material in the accretion disk surrounding the black hole when it is superheated to millions of degrees by the intense friction generated by the particles of dust, gas & other matter in the disk colliding countless times with each other.

The inward spiral of matter in a supermassive black hole’s accretion disk – that is, at the centre of a quasar – is the result of particles colliding & bouncing against each other & losing momentum.

That material came from the enormous clouds of gas, mainly consisting of molecular hydrogen, which filled the universe in the era shortly after the Big Bang.

There is a maximum rate set by the Eddington limit at which a black hole can accrete matter before the heating of the infalling gas results in so much outward pressure from radiation that the accretion stops.

Some quasars have radio jets, which are highly collimated beams of plasma propelled out along the rotation axis of the accretion disk at almost the speed of light.

These jets emit beams of radiation that can be observed at X-ray & radio wavelengths (and less often at optical wavelengths).

What distinguishes an “active” galactic nucleus from other galactic nuclei (90–95 percent of large galaxies that are currently not quasars) is that the black hole in an active nucleus accretes a few solar masses of matter per year, which, if it is accreting at around 1 percent or more of the Eddington rate, is sufficient to account for a typical quasar with a total luminosity of about 10^39 watts. (The Sun’s luminosity is about 4 × 10^26 watts.)

Quasars are baby galaxies if you will.

Have a WELL-DESERVED cookie 🍪, this has gotten WAY out of hand.

Apologies.

Quasar, is an astronomical object of very high luminosity found in the centres of some galaxies and powered by gas spiralling at high velocity into an extremely large black hole.

Quasars form when extreme amounts of material (dust and gas) fall into the accretion disk of a supermassive black hole. The gravitational forces over these materials create enormous amounts of friction, increasing the temperatures and producing a huge output of electromagnetic radiation

Quasars are important for several reasons: They are among the brightest objects known in the Universe and therefore are visible to the greatest possible distances.

They appear to live in galaxies, so they can help us understand galaxy formation and evolution

report from the front lines of cosmology

"

Could a white hole be a special type of result from a supernova when it exists near a black hole?

ChatGPT: Poe

The concept of a white hole is a hypothetical region of spacetime that is the reverse of a black hole. While a black hole is a region from which nothing, including light, can escape due to its intense gravitational pull, a white hole is a region into which nothing can enter. In other words, a white hole is a theoretical object that only allows matter and energy to flow outward.

Currently, there is no direct evidence for the existence of white holes in our universe, and they remain speculative in nature. While black holes are predicted by general relativity and have been indirectly observed through their gravitational effects, white holes are a less well-established concept.

That being said, if we consider the hypothetical scenario in which a white hole exists near a black hole, it would depend on the specific properties and interactions between these two objects. It is difficult to provide a definitive answer as this scenario lies within the realm of theoretical physics and is subject to speculation.

However, it is worth noting that black holes and white holes are typically discussed as separate entities in theoretical physics. Black holes are formed from the gravitational collapse of massive stars, while white holes are often considered as a hypothetical consequence of certain solutions to Einstein's field equations. The concept of a white hole arising as a specific result of a supernova near a black hole is not a commonly proposed scenario in the scientific literature.

In summary, the existence and properties of white holes are still largely theoretical, and their interaction with black holes remains speculative. Further research and theoretical developments are necessary to explore these concepts in more detail."

Clearly this is a question that almost no one is able to answer. I call it the front lines of physics, because it seems the only valid answer is that we need to learn more, and observe more, we need to see for the first time a supernova near a black hole, probably in a quasar - could a supernova occur in a quasar? (note, a quasar is a disk of charged energy in close orbit around a black hole, quasars are thought to be the brightest objects in the sky, aside from supernovae themselves)

Could a supernova occur within a quasar?

ChatGPt: Poe

Quasars are extremely luminous and energetic objects located at the centers of galaxies. They are powered by the accretion of mass onto supermassive black holes. Supernovae, on the other hand, are stellar explosions that occur at the end of a massive star's life.

While it is theoretically possible for a supernova to occur within a quasar host galaxy, it is highly unlikely for a supernova to occur within the immediate vicinity of the supermassive black hole that powers the quasar. The intense gravitational forces near the black hole would disrupt the formation and stability of stars in its immediate vicinity, making it unlikely for a massive star to reach the end of its life and go supernova in such an environment.

However, it is worth noting that galaxies hosting quasars are typically active and dynamic environments. They can contain regions of star formation, where massive stars could be present. In these star-forming regions, it is possible for a supernova to occur. However, it would be at a considerable distance from the central supermassive black hole that powers the quasar.

In summary, while a supernova could occur within a galaxy hosting a quasar, it is highly unlikely for a supernova to occur in the immediate vicinity of the central supermassive black hole that powers the quasar. The extreme gravitational forces and disruptive nature of the black hole environment make it an inhospitable place for the formation and stability of stars.

Is it possible that the timeless and calm nature of white hole could create the eternal cosmic background radiation within another universe?

ChatGPT: Poe

The concept of white holes is still largely speculative and not well-established in current scientific understanding. However, if we consider the hypothetical scenario in which white holes exist and possess timeless and calm characteristics, it is difficult to directly link them to the creation of the cosmic microwave background radiation (CMB) in another universe.

The cosmic microwave background radiation is a form of electromagnetic radiation that permeates the entire observable universe. It is thought to be residual radiation from the early stages of the universe, specifically from a time known as recombination when the universe became transparent to photons.

The CMB is believed to have originated from a hot, dense, and highly energetic state known as the primordial plasma. As the universe expanded and cooled, the photons within this plasma gradually decoupled from the matter and started to travel freely, eventually becoming the CMB we observe today.

While white holes are often described as regions from which matter and energy can only flow outward, it is not clear how this property would directly lead to the creation of the CMB. The origin of the CMB is generally attributed to processes that occurred during the early stages of the universe's expansion, such as the recombination event mentioned earlier.

It is important to note that our understanding of the early universe and the mechanisms behind the CMB is based on the framework of the Big Bang theory and the physics of general relativity. White holes, as currently understood, do not have a well-developed theoretical foundation and are not included in our current understanding of the universe's evolution.

Overall, while it is intriguing to speculate about the potential connections between white holes and the cosmic microwave background radiation, it is currently beyond the scope of our scientific knowledge to establish a direct relationship between these concepts. Further theoretical advancements and empirical evidence would be required to explore such possibilities in detail.

This artist’s impression shows the material ejected from the region around the supermassive black hole in the quasar SDSS J1106+1939. This object has the most energetic outflows ever seen, at least five times more powerful than any that have been observed to date. Quasars are extremely bright galactic centres powered by supermassive black holes. Many blast huge amounts of material out into their host galaxies, and these outflows play a key role in the evolution of galaxies. But, before this object was studied, the observed outflows weren’t as powerful as predicted by theorists. The very bright quasar appears at the centre of the picture and the outflow spreads about 1000 light-years out into the surrounding galaxy.

Giant black hole formed puzzlingly fast at dawn of cosmos

Astronomers have found by far the most distant and earliest quasar ever seen, a cosmic beacon shining so soon after the big bang that standard theory can’t explain how it was built. Among the most luminous objects in the cosmos, quasars are powered by supermassive black holes in the center of galaxies, which suck in matter so voraciously that it becomes white hot from friction and glows brightly enough to be seen across the universe. Astronomers thought the black holes formed stepwise within early galaxies, as giant stars collapsed and merged, but quasars detected from when the universe was less than 1 billion years old have challenged the idea. “We were already concerned,” says Anna-Christina Eilers of the Massachusetts Institute of Technology. The new one, dubbed UHZ-1, which blazed when the universe was less than 450 million years old, has made that scenario untenable. It’s not just UHZ-1’s early date, confirmed in a preprint posted on 5 August. The observations show its black hole is so large compared with the galaxy around it that it can’t have evolved slowly at the galaxy’s heart, but must have formed rapidly, by an entirely different process.

Astronomers have found the brightest known object in the universe—a glowing core of a galaxy, called a quasar, located 12 billion light-years away.

Quasars, as a whole, are the brightest objects in the cosmos, each consisting of a supermassive black hole that’s actively devouring an orbiting disc of gas and dust. But the black hole in this record-setting quasar is gobbling up more than a sun’s-worth of mass every day, making it the fastest growing black hole scientists have ever seen, according to a statement from the European Space Agency (ESA).

The gargantuan object stretches about seven light-years across, and it puts our sun’s luminosity to shame—the quasar shines more than 500 trillion times brighter than the star in our solar system, the researchers reported Monday in the journal Nature Astronomy.

“This quasar is the most violent place that we know in the universe,” Christian Wolf, lead author of the new study and an astrophysicist at Australian National University, tells Marcia Dunn of the Associated Press (AP).

“It is a surprise that it has remained unknown until today, when we already know about a million less impressive quasars,” study co-author Christopher Onken, an astronomer at Australian National University, says in the statement. “It has literally been staring us in the face until now.”

Supermassive black holes, which are at the heart of every quasar, grow by pulling stars and gas clouds into a ring of orbiting material called an accretion disc and swallowing them up. The matter circling the black hole rubs together, creating friction that releases glowing heat that can be seen from far away.

Researchers unknowingly spotted the ultra-bright quasar, officially called J059-4351, in images taken in 1980 by the Schmidt Southern Sky Survey, a telescope in Australia—but at first, they mistakenly identified it as a star. Typically, astronomers find quasars using machine-learning models trained to survey large areas of the sky for objects that look like known quasars in existing data. This makes it harder to spot unusually bright quasars that are unlike anything seen before.

But last year, the study authors determined the object was in fact a quasar using a telescope at the Siding Spring Observatory in Australia. They followed up with data from the Very Large Telescope in Chile to determine the quasar was the brightest ever seen.

“The exciting thing about this quasar is that it was hiding in plain sight and was misclassified as a star previously,” Priyamvada Natarajan, an astrophysicist at Yale University who did not contribute to the findings, tells the AP.

Around the quasar, the accretion disk is 15,000 times the length between the sun and Neptune, per the ESA, and its black hole weighs about the same as 17 billion suns.

The black hole in the quasar is ravenous, consuming an amount of material equivalent to as much as 413 suns each year, according to New Scientist’s Alex Wilkins. As a result, the disc glows brightly as it releases unfathomable amounts of energy.

“It looks like a gigantic and magnetic storm cell with temperatures of 10,000 degrees Celsius, lightning everywhere and winds blowing so fast they would go around Earth in a second,” Wolf tells the Guardian’s Tory Shepherd.

Because the accretion disc spans such a long distance, it could be possible for future researchers to accurately measure the mass of the black hole at the center, Christine Done, a physicist studying black holes at Durham University in England who was not involved in the research, tells New Scientist.

“This is big enough and bright enough that we could resolve it with our current instruments,” Done says to the publication. “We could have a much more direct measure of the black hole mass in this monster, and that’s what I did get quite excited about.”

The light from the quasar took about 12 billion years—the majority of the history of the universe—to reach us. Its black hole would have stopped growing long ago, Wolf writes in the Conversation. Since much of the gas that once floated freely around the cosmos has consolidated into stars that travel on long orbits around black holes, these massive objects no longer have as much material to feed on as they did in the early universe.

Wolf tells the Guardian that he doesn’t think anything will ever top this record for the universe’s brightest object.
