Binary Black Hole Merger GW231123 With 190-265m(Sun)

In 2023, two LIGO observatories detected the gravitational wave signal GW231123 at a distance of several billion light-years. Astronomers interpret the signal as a merger of a pair of black holes with a total mass of 190 to 265 solar masses, the highest combined mass ever observed. This event created an intermediate-mass black hole IMBH with a mass of 225 solar masses.
This is the LIGO Observatory in Hanford, USA. LIGO is the Laser Interferometer Gravitational-Wave Observatory, a large-scale physics experiment that detects cosmic gravitational waves.
This is the signal of the gravitational wave event observed by the detectors in Hanford and Livingston. Despite its short duration of 0.1 second the signal was detected with a high signal to noise ratio.
The two black holes with an estimated mass of 137 and 103 solar masses distort space and time in the surrounding region. Gravitational waves are ripples in spacetime that travel through space at the speed of light. The plane of space distortion is orthogonal to the wave propagation direction.
Theoretically, black holes with 60 to 130 solar masses should be rare due to pair-instability supernovae. Massive stars have a very high core temperature of over 300 million Kelvin. Photons are converted in pairs of electrons and positrons. The drop in radiation pressure causes a core collapse and an explosion due to runaway fusion reactions.
This diagram supernovae versus mass and metallicity predicts the outcome. Population III stars with a low metallicity and a mass of 130 to 250 solar masses are in the pink region at the bottom right. They are completely destroyed by a supernova explosion without leaving a remnant behind.
Intermediate-mass black holes could have been formed by mergers of smaller black holes. Or they could be the product of a runaway collision of massive stars in dense star clusters. Or they could be primordial black holes formed in the Big Bang.
The most massive O- and B-type stars with their short lifetimes of a few million years are an important part of the evolution of galaxies. They made a rapid increase in metallicity in the first two billion years after the Big Bang possible.

Everyone in the nearby star systems go "Weeeeeeee!!"

During this merger about 15 solar masses were radiated in gravitational waves. As energy equivalent, this was more than ten times the energy radiated by all stars in the visible universe in the same time.

I find the 0.1 s signal that they were able to detect the most fascinating.

Greetings from Richland!

I live in Richland, where the observatory is located. Been there a couple times and holy shart are those people incredibly smart and dedicated. Just absolutely mind bending.

I would love to visit America one day. I have worked with several people from America. They were all very nice.

I remember going to a symposium on gravitational waves at Cardiff University while studying Astrophysics. They discussed the physics behind the Gravitational Wave detectors and it was fascinating.
It's so cool seeing that it worked.
komradekristoph
Seeing this just makes my brain hurt even more after reading a theory that our universe might be inside of a black hole. We're like those Russian dolls...

How fast is the rotation?
heyletsbefriends
yes
Gravitino74
You mean the rotation of the resulting black hole?
bitchesonmonday
Yes
Gravitino74
The spin parameter of the final BH is reported to be 0.84, so the virtual equator of the event horizon is rotating with a substantial fraction of the speed of light, ~200,000 km/s
Oktay74tn
The rotation speed is not mentioned but it is relativistic.

265m ≈ 869 feet, 5 inches

in this context, 3C clearly means 3 times the speed of light...

It's crazy we can detect the gravitational effects from something that happened several billion light years away. Even more amazing that these only had a combined mass of up to 265 solar masses.
Oktay74tn
Yes, that's the point. Plus intermediate-mass black holes are the least understood type of black holes.
sigmatis
If this is the largest combined pair mass ever found, does that mean we have not yet detected a black hole merging with a supermassive black hole yet?
Oktay74tn
Yes. Imagine if you had data from many black hole mergers then you could get a better understanding of the black hole and galaxy co-evolution.

The image shown here is fiction, imagination that's not even a plausible background of galactic stars. It is not even a "merger" being shown. The actual detection is a blip on a meter.
Rehvin
Is it possible at all to depict the exact image or video with current technology to explain the science behind black holes and how they form through going supernova? Is supernova the only way black hole events are formed?
Pevinsghost
It's theorized to not be the only way, just the way we have the most strong evidence for. Enough energy density could cause one. There's a formation involving antimatter theorized to have happened immediately following the big bang (primordial black holes, mentioned in the video.) the supernova works the same way white dwarf form, the star gets low on "fuel", can't create enough energy to resist collapse, the collapse releases an explosion of energy flinging outer layers of the star into space.
RedClaws23
Astrophysicist here: science communication matters and is valid. Saying 'there are three states of matter' is fiction. Saying 'hydrogen has a mass of 1' is fiction. 'the sun will eventually expand and consume earth.' Fiction. Most images of the sun. Fiction. 'Water boils at 100°C.' Fiction. 'Space is cold.' Fiction.
None of these things are truly correct, but they are all far far more easily grasped by a general audience than the full technical details. Visualizations are a part of that.

Maybe, maybe not. I honestly have no clue but, for the 95% of the people that can't in any way envision what the text above describes (myself included), maybe a picture helps to understand or at a minimum, retain interest in the subject matter.
astronomygeek7
Can we appreciate that cgi though? Impressive work.
fubizdaddie
We can appreciate the CGI, but we definitely shouldn't be impressed by it. The other reply is right, this isn't an impressive sim or something, it's literally windows 95 screensaver quality. It's a static spin with some distortion. Also, the AI Einstein voice is not great either.
sirnoahfence
It's literally him speaking in these, but whatever makes you feel better about yourself.
TsubakiTragic
This? Not a chance. Sry to disappoint, but this animation is akin to Disney flip cards; it's showing two black circles circling and black holes don't look like 'black holes'.
insaaanity
I wish they had picked someone who speaks a bit more clearly and with at least a modicum of enthusiasm.
Oktay74tn
Thank you very much for your feedback. I am a more introverted person but I understand your point.
Affray
Your flatly delivered thickly accented speaking sounds exactly like the vast majority of scientists talking about their craft. Works for me.
insaaanity
I had no idea it was you, I am so sorry.
I believe all you need is to do a test reading first and have someone who is good with audio recording lend you a hand. There's nothing fundamentally wrong with you, I just got the impression that you are just reading it off a piece of paper in a poorly setup and/or low quality mic.
Oktay74tn
The full script of all my recent videos is in the description field.
Oktay74tn
No problem. I test read each paragraph while I write the script. That is a good trick.

For what it's worth, I very much prefer this over some generic A.I. reading and I'm afraid you became a victim of association, since hearing it reminded me of rather dry lectures of the past. I'm grateful you're sharing this and didn't mean to suggest that I can make demands over freely and generously shared content. I thought someone lazily picked out something random from the Internet and didn't care to pick something with better sound quality. You went to the effort of actually contributing..
insaaanity
...of value, which I have infinitely more respect for and where I won't hold minor nitpicks against you. It is a great information piece and I would have made any criticisms much more nuanced, constructive and diplomatic had I known it came from you.
