Black holes slow down the growth of dwarf galaxies – astronomers are surprised by 2,000,000 mph of wind

NGC1569 is a star formation galaxy. Credit: HST / NASA / ESA UC Riverside astronomers note that large winds associated with active black holes in small galaxies suppress star formation. Black holes in the centers of dwarf galaxies have a significant impact on their evolution Galaxies by suppressing star formation. Dwarf galaxies are small galaxies that contain between 100 million …

The cosmic web drives stars and supermassive black holes into place

<! – -> Astronomers now view our universe as a cosmic web consisting of massive filaments of galaxies separated by huge cavities. We do not know exactly how this cosmic web is. Most of our research has been done using computational models, in particular the model of cold dark matter for galaxy formation, which is currently favored by most cosmologists. …

Three supermassive black holes on extremely rare collision course [Video]

Photo credit: X-ray: NASA / CXC / George Mason Univ./R. Pfeifle et al .; Optical: SDSS & NASA / STScI Astronomers have discovered three huge black holes in a titanium collision of three galaxies. The unusual system was captured by several observatories, including three NASA space telescopes. "We were only looking for pairs of black holes at the time, and …

Black holes, as we know them, may not exist

If you dived into a black hole (something we would not recommend), you would probably find a singularity or an infinitely small and dense dot in the center. Or physicists have always thought that. But now two scientists suggest that some black holes could not be black holes at all. Instead, they can be weird objects full of dark energy …

Collisions with black holes: Three supermassive black holes are about to crash science | news

The unexpected black hole trio was discovered by many different observations of the universe, including NASA's Chandra X-ray Observatory. Originally, astronomers wanted to explore pairs of black holes, but were pleasantly surprised to find three so close together. The three black holes are supermassive, which means that they are hundreds of thousands to billions of times heavier than our sun. …

These three supermassive black holes could one day unite

The triple fusion Photo : X-ray: NASA / CXC / George Mason Univ./R. Pfeifle et al .; Optical: SDSS & NASA / STScI Scientists have found the best evidence yet for a trio of supermassive black holes in seemingly merging galaxies, a new paper states. The evolutionary theories of the universe predict that galaxies and the enormous black holes in …
