The Event Horizon Telescope (EHT) combined collaborative radio data from an international array over 4 different continents to create the first ever polarized-light image of Sagittarius A*, Milky Way's very own supermassive black hole, or at least an image the dusty/gassy/plasma accretion disk around it. The image looks cool as hell, but also reveals an organized pattern in the magnetic field similar to the one found in M87*, a thousand-times-more-massive supermassive black hole in the distant M87 galaxy.

The Next Gen EHT plans to collect these images over months and years to create black hole videos. Today was another great day for science!

CAN TWO SUPERMASSIVE BLACK HOLES MERGE??

Blog#440

Saturday, September 28th, 2024.

Welcome back,

A team of astrophysicists that includes the University of Toronto’s Gonzalo Alonso-Álvarez has shown that pairs of supermassive black holes can merge together into a single, larger black hole – a major breakthrough in addressing what is known as the "final parsec problem."

longstanding astrophysics problem refers to a discrepancy between the detection of gravitational signals permeating the universe – which astrophysicists previously hypothesized had emanated from millions of merging pairs of supermassive black holes (SMBHs) – and theoretical simulations which showed that the approach of SMBHs stalls when they’re roughly one parsec (about three light years) apart.

Not only did the final parsec problem conflict with the theory that merging SMBHs were the source of the gravitational wave background, it was also at odds with the theory that SMBHs – each billions of times more massive than our Sun – grow from the merger of less massive black holes.

The new research, published in Physical Review Letters, has shown that pairs of SMBHs can indeed break through the one-parsec barrier and merge into a single black hole. This is demonstrated by calculations showing that SMBHs continue to draw closer because of previously overlooked interactions with particles within the vast cloud of dark matter surrounding them.

“We show that including the previously overlooked effect of dark matter can help supermassive black holes overcome this final parsec of separation and coalesce,” says Alonso-Álvarez, a post-doctoral fellow in the department of physics at U of T’s Faculty of Arts & Science and the department of physics and Trottier Space Institute at McGill University, who is first author on the paper. “Our calculations explain how that can occur, in contrast to what was previously thought.”

SMBHs are thought to lie in the centres of most galaxies. When two galaxies collide, the SMBHs fall into orbit around each other; as they revolve around each other, the gravitational pull of nearby stars tugs at them and slows them down, causing them to spiral inward toward a merger.

Previous merger models showed that when the SMBHs approached to within roughly a parsec, they begin to interact with the dark matter cloud or halo in which they are embedded. These models indicated that the gravity of spiraling SMBHs throws dark matter particles clear of the system.

The new model introduced by Alonso-Álvarez and co-authors James Cline, a professor at McGill University and the European Organization for Nuclear Research (CERN) in Switzerland, and Caitlyn Dewar, a graduate student at McGill, reveals that dark matter particles interact with each other in such a way that they are not dispersed. The density of the dark matter halo remains high enough that interactions between the particles and the SMBHs continue to degrade the SMBH’s orbits – clearing a path to a merger.

“The possibility that dark matter particles interact with each other is an assumption that we made, an extra ingredient that not all dark matter models contain,” says Alonso-Álvarez. “Our argument is that only models with that ingredient can solve the final parsec problem.”

The background hum generated by these colossal cosmic collisions is made up of gravitational waves of much longer wavelength than those first detected in 2015 by astrophysicists operating the Laser Interferometer Gravitational-Wave Observatory (LIGO).

Those gravitational waves were generated by the merger of two black holes, both some 30 times the mass of the Sun.

The background hum has been detected in recent years by scientists operating the Pulsar Timing Array. The array reveals gravitational waves by measuring minute variations in signals from pulsars, rapidly rotating neutron stars that emit strong radio pulses.

I was looking at your project: geocentric, and I find it really cool! I was wondering if you had more on black holes. A bit terrifying to know the largest and most powerful cosmic entities are all-consuming eyes of darkness. Or maybe I'm just thinking about TON-618/Phoenix A (whichever's biggest lol) because Sagittarius A still looks like a funky dude :)

ooo thank you!! i haven't messed around with black holes in my story too much besides what i have for sagittarius a*, but i can talk some more about them hehe.

as you noted, sagittarius (or sag) is a bit more of a funky/goofy dude, which is a reference to how the actual black hole is fairly dormant! he's not spitting out jets or actively eating anything, he's just kind of sitting there in the middle of the milky way and having a good time.

(more stuff under readmore)

most galaxies will have a central super massive black hole (smbh) , and have some close relationship with them. for some, the smbh might torment their galaxy, especially if theyre super active and constantly blasting out radiation. but for others, like milky way and sag, they may have a romantic relationship. i designed black holes and galaxies around the same time, so their designs are meant to compliment each other. galaxies lack a mouth, whereas black holes are pretty much all mouth. this creates an interesting relationship, with smbhs acting as the mouth of their galaxy, often serving as their voice.

i haven't designed too many stellar-mass black holes, but they'd probably look similar to sag, maybe with less colors and much smaller. below is a stellar black hole (cygnus x-1) that i designed based off of tom cardy's H.S. song heheh. stellar mass black holes come from the most massive of stars dying violently in a supernova. while they often still hold the memories and personality from when they were a star, they get dramatically changed from their new connection to The Void.

at star death, black holes get exposed to The Void, the shadow of The Universe that represents dark matter, dark energy, and all that empty space in space. The Void allows for black holes to gain some sort of higher cosmic understanding of reality. this makes most black holes mysterious, hard to understand beings. The Void also gifts them many cosmic powers, such as the power to manipulate spacetime!

(this mirrors how galaxies and the largest of stars often have a connection to The Universe)

most black holes are able to manipulate their own size, appearing larger or smaller. many black holes are also able to almost teleport through space, either literally teleporting through worm holes of their own making, or traveling over light speeds. they can bend gravity like a limb, pulling and pushing on others around them. overall, scary fellas! super massive black holes will typically have some secondary power unrelated to spacetime manipulation as well, such as sag who can manipulate dreams.

but yeah, thats basically my current ideas for how black holes work. i need to try personifying some of the more "scary" black holes, such as TON-618 and all that, so I can really delve into what makes these things terrifying hehehe. thank you for the ask!

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.

The SMBH of Fanon and The Spaghetti fixation of Jiang Cheng

A supermassive black hole (SMBH or sometimes SBH). Black holes are a class of astronomical objects that have undergone gravitational collapse, leaving behind spheroidal regions of space from which nothing can escape, not even light. Every large galaxy has a supermassive black hole at its center. In astrophysics, spaghettification (sometimes referred to as the noodle effect) is the vertical stretching and horizontal compression of objects into long thin shapes (rather like spaghetti) in a very strong, non-homogeneous gravitational field. It is caused by extreme tidal forces. In the most extreme cases, near a black hole, the stretching and compression are so powerful that no object can resist it.

What do these terms mean in context of Jiang Cheng? One is at the focal point of part of the novel Jiang Cheng is significantly tied to the thematics and consequences surrounding our main character Wei Wuxian. As our protagonist, Jiang Cheng being Wei Wuxian's emotional antagonist is central to the creation of the novel and it's plot progression for its continued arcs for him. He is important for what conclusions and continued strength Wei Wuxian finds for his convictions and actions.Jiang Cheng is a fellow needed center of our Story universe.

There are irrefutable "laws" of this story universe made by its creator (Mo Xiang Tong Xiu). He had been a childhood friend of Wei Wuxian, he had blamed Wei Wuxian for his tragedies, he had wanted him to be his support, he had wanted him under his loyalties, he tried to protect Wei Wuxian, he immediately regretted this protection when faced with consequences. His jealousy and inferiority towards someone that was supposed to be beneath him that continued to overshadow him in ability and fame grew. This hate overtook any care he had until he was able to see nothing but flaw and wrong and finally used that to say he must be killed and deserved death. This hate was excusable until he was faced with his own part in their unraveling relationship and stark morality that was never the same.

Fandom, likes to twist this center until it is stretched out into unbelievable extremes to say that all that was done by Jiang Cheng was either appropriate by human natural response, or it was one of our natural centers, Wei Wuxian, is actually wrong and needs to be morphed to fit the now widened hole that is distorting the created universe.

This effect now begins to leak out of the intended universe to stretch out into what it means for the fact that the audience is intended to perceive by its creator. The natural facts of the creator are now wrong, they are not intended, it is a lie and now I can say intended natural morality is perceived differently because I see Jiang Cheng as personally correct, or, simply because I feel bad he must and needs a happier ending because his universe's natural conclusion for him is incorrect. I can become the blackhole that stretches his natural intentions to be something that is unfamiliar to the work, I can cover it in falsehoods that seem natural in language as I speak and use human empathy. Reasoning is not needed when I use emotion to distort a reaction I want to invoke that was never intended by creator intent. I feel it, so it must be, if others do not, I will make them even if I need to change the words and actions within his natural universe and creator and even him to cater to this effect.

Jiang Cheng will be changed until he and its world make me feel comfortable to inspire a stretched perception that has voided its original state of being. Fact is not fact any longer when I try to insert emotional fallacy into indisputable story trajectory and author intent is dead.
