When two black holes collide into each other to form a new bigger black hole, they violently roil spacetime around them, sending ripples called gravitational waves outward in all directions. Previous ...
A remarkable prediction of Einstein's theory of general relativity -- the theory that connects space, time and gravity -- is that rotating black holes have enormous amounts of energy available to be t...

When the most massive stars die, they collapse under their own gravity and leave behind black holes. When stars that are a bit less massive die, they explode in supernovas and leave behind dense, dead...

Young galaxies blaze with bright new stars forming at a rapid rate, but star formation eventually shuts down as a galaxy evolves. A new study, published January 1, 2018, in Nature, shows that the mass...
Black holes are famous for their muscle: an intense gravitational pull known to gobble up entire stars and launch streams of matter into space at almost the speed of light.It turns out the reality may...

AGN Reverberation Mapping: the pc Scale Garden of Massive Black Holes
Active Galactic Nuclei RM for cosmology
2016/7/22
Reverberation of Active Galactic Nuclei (AGNs) is delivering information of parsec scale structure of galactic nuclei from black hole accretion disks, broad line regions to the inner edge of dusty tor...
Pairs of Supermassive Black Holes in Galaxies May Be Rarer Than Previously Thought（图）
Supermassive Black Holes Galaxies Previously Thought
2015/9/25
There may be fewer pairs of supermassive black holes orbiting each other at the cores of giant galaxies than previously thought, according to a new study by astronomers who analyzed data from the Nati...
Earlier this year, astronomers discovered what appeared to be a pair of supermassive black holes circling toward a collision so powerful it would send a burst of gravitational waves surging through th...
Neutron Stars Strike Back at Black Holes in Jet Contest
Neutron Stars Strike Back Black Holes Jet Contest
2015/8/13
Some neutron stars may rival black holes in their ability to accelerate powerful jets of material to nearly the speed of light, astronomers using the Karl G. Jansky Very Large Array (VLA) have discove...
