"Ultramassive black holes have been found where our results predicted we should look to find them, in the centers of nearby BCGs. What surprises me is how black holes of all sizes are essentially littered everywhere in the universe," Natarajan said. "Galaxies seem to harbor multiple black ho...
Massive Black Hole Mergers: Can We See What LISA Will Hear? Coalescing massive black hole binaries are formed when galaxies merge. The final stages of this coalescence produce strong gravitational wave signals that can be detected by the space-borne LISA. When the black holes merge in the prese...
We find that velocities of many tens to a few hundred km/sec can be achieved fairly easily. The recoil probably never exceeds about 500 km/sec.doi:10.1007/11403913_64Hughes, Scott A.Favata, MarcHolz, Daniel E.Springer Berlin HeidelbergS.A. Hughes, M. Favata, D.E. Holz, How black ...
"When you go the extreme range of black hole masses,you find this effect can be dominant and will actually lead to the black holeswallowing up the whole galaxy," Hernandez said. But this does not seem to have happened to the supermassiveblack holes thought to occupy the centers of most ga...
Two massive black holes smashed together and completely changed what we know about the universe. This physics-altering collision simply doesn't make sense.
It's a nice idea. It would be nicer still if we could find similar middleweight black holes in star clusters today. A few promising objects called ultraluminous X-ray sources (ULXs) have been found in nearby galaxies. They are seemingly bright enough to be based around biggish holes. But...
When galaxies merge, we expect them to produce binary black holes (BBHs.) BBHs orbit one another closely, and when they merge, they produce gravitational waves that have been detected by LIGO-Virgo. The upcoming Vera Rubin Observatory should be able to find them before they merge, which wou...
But what would it be like to make the next leap: to visit—and even enter—a black hole? We asked the experts. First, to survive long enough to explore a black hole, you must find a big one, says Janna Levin, Ph.D., an astrophysicist at Barnard College of Columbia University. ...
