#SimulatedUniverses
I am going to post some gorgeous first simulations of jet feedback from the supermassive black hole in a massive cluster of galaxies, simulated by 1st year PhD student Stefano Sotira (Unibo).
All runs are done with the ENZO code, in a setup similar to a series of Li & Bryan 2014,15...articles.
This is the gas density in a slice through the cluster.
Observers described it as an almost demolition derby-like collision of stellar remnants and stars in the chaotic neighborhood of the galaxy's central supermassive black hole. The source of the GRB flash lay just 100 light-years away from the heart of the galaxy. It turned out to be in very close proximity to the central...
"Astronomers have found a background din of exceptionally long-wavelength gravitational waves pervading the cosmos. The cause? Probably supermassive black hole collisions, but more exotic options can’t be ruled out."
Tantalizing set of papers, showing potential gravitational wave signal from merging supermassive black holes. Based on decades long monitoring and timing of a set of pulsars with big radio telescopes in Europe (including 100m Effelsberg I used during my PhD), America, Asia, Australia. #EPTA press release: https://www.mpifr-bonn.mpg.de/7918483/epta-jun2023
Astronomers using NASA's Hubble Space Telescope have come up with what they say is some of their best evidence yet for the presence of a rare class of "intermediate-sized" black hole that may be lurking in the heart of the closest globular star cluster to Earth, located 6,000 light-years away.
⚫️ #BlackHoles are usually thought of as something that will destroy and consume everything in the #universe.
#Hubble telescope recently captured a black hole weighing about 20 mil. Suns flying at millions of km per hour.
🌠 A black hole leaves behind a 200,000 light year long trail of newly born stars (2x diameter of the Milky Way). The black hole is moving through dense clouds of gas and dust, at speed which prevents it from absorbing them. As a result, the gas and dust are turning into stars.
On the left is a picture of the supermassive black hole located in the M87 galaxy, which was first released in 2019 by the EHT team. On the right is a fresh image of the same black hole, generated by the PRIMO algorithm using the identical data set (2023).
Sharing some of my favorite #Hubble images from the #NASA archives to commemorate the space telescope’s 33rd anniversary. We should take a moment to appreciate the beauty and wonder of the universe.
Information about the images + Hubble facts, a thread: 1/x
This is #NGC2525, a captivating galaxy located in the constellation of #Puppis, nearly 70 million light-years from Earth. It is notable for being home to a supermassive black hole. It is being observed by the #HubbleSpaceTelescope to measure the universe's expansion rate.
It turns out #BlackHoles are a lot like cats 😼 Especially, they play with their food 🐀
You don't believe me?
Remember how a #cat plays with a mouse: catches it, releases it, catches it again, releases it again ... Turns out, black holes can do the same with stars: they can catch and partially disrupt a star, release it, wait until it approaches again, play with it a bit more, release it, wait for the next approach:
