Black holes stunt growth of dwarf galaxies
by
•Astronomers have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the evolution of these galaxies by suppressing star …read more Source:: Science
Supercomputer shows ‘Chameleon Theory’ could change how we think about gravity
by
•Supercomputer simulations of galaxies have shown that Einstein’s theory of General Relativity might not be the only way to explain how gravity works or how galaxies form. …read more Source:: Science
Astronomers find pairs of black holes at the centers of merging galaxies
by
•For the first time, a team of astronomers has observed several pairs of galaxies in the final stages of merging together into single, larger galaxies. Peering through thick walls of …read more Source:: Science
Cosmic fountain offers clues to how galaxies evolve
by
•Galaxy evolution can be chaotic and messy, but it seems that streams of cold gas spraying out from the region around supermassive black holes may act to calm the storm. …read more Source:: Science
Milky Way’s supermassive black hole may have ‘unseen’ siblings
by
•Astronomers predict that galaxies with a mass similar to the Milky Way should host several supermassive black holes. …read more Source:: Science
Black hole and stellar winds form giant butterfly, shut down star formation in galaxy
by
•Researchers have completed an unprecedented ‘dissection’ of twin galaxies in the final stages of merging. The new study explores a galaxy called NGC 6240. While most galaxies in the universe …read more Source:: Science
Black holes from small galaxies might emit gamma rays
by
•Researchers have discovered seven galaxies that could shake up what astrophysicists thought they knew about how the size of a galaxy — and the black hole at its center — …read more Source:: Science
Distant galaxy group contradicts common cosmological models, simulations
by
•Astronomers have determined that Centaurus A, a massive elliptical galaxy 13 million light-years from Earth, is accompanied by a number of dwarf satellite galaxies orbiting the main body in a …read more Source:: Science
Newborns or survivors? The unexpected matter found in hostile black hole winds
by
•The existence of large numbers of molecules in winds powered by supermassive black holes at the centers of galaxies has puzzled astronomers since they were discovered more than a decade …read more Source:: Science
