"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...
You can also get black holes when dense objects, like neutron stars, collide with one another. And then there are the supermassive black holes at the heart of every galaxy. And to be honest, astronomers still don’t know how those monsters formed....
Not surprisingly, the largest black holes, calledsupermassive black holes, are much rarer than their smaller cousins. The researchers found that in every cubic megaparsec of space (where a megaparsec is one million parsecs, or 3.26 million light-years), our universe hosts roughly 50 million solar...

Black Holes:Black holes were predicted to exist using mathematics and theoretical physics. However, it was not until late in the 20th century that astronomers found solid proof of their existence.Answer and Explanation: Most black holes are made from the death of massive stars. When the process...
Cosmologists have an expanding problem ... literally. Could gravitational waves from merging black holes be the answer?
The same kind of problem can be found for globular clusters, which show cores in their density profiles but should be cuspy if they where formed through a cold collapse(King, 1962; Jenkins et al., 1998). We are showing how small, massive, and compact objects can efficiently transform ...
“Intermediate-Mass Black Holes are difficult to observe,” explains the GSSI researcher, “the current observational limits do not allow us to say anything about the population of IMBHs with masses between 1,000 and 10,000 solar masses, and they also represent a headache for scientists in ter...
Functions of this form are often used as models to describe the density profile of dense stellar clusters. For black holes the spin can be characterized via the angular momentum parameter [Math Processing Error], where J is the angular momentum and M the mass of the black hole. It has the...
One of the most fascinating theories he came up with is that black holes, the universe's swiffer, can actually evaporate over vast periods of time. Quantum theory suggests there arevirtual particlespopping in and out of existence all the time. When this happens, a particle and its antiparticl...
