These phantom quasars are brighter than they should be, what's going on? Hint: it's not aliens.
In space, it sometimes happens that two galaxies are aligned in just the right way that the closer galaxy distorts and magnifies the appearance of the one behind it. For astronomers, finding these alignments is like coming across giant, cosmic magnifying glasses.
Which comes first, the supermassive black holes that frantically devour matter or the enormous galaxies where they reside?
Astronomers are hunting an elusive target: rogue black holes that have been ejected from the centers of their home galaxies.
WASHINGTON (Reuters) - A supermassive black hole appears to be homeless in the cosmos without a galaxy to nestle in, Hubble Space Telescope scientists reported on Wednesday.
The detection of a super massive black hole without a massive host galaxy is the surprising result from a large Hubble and VLT study of quasars. This is the first convincing discovery of such an object. One intriguing explanation is that the host galaxy may be made almost exclusively of dark matter.
Using a new computer model of galaxy formation, researchers have shown that growing black holes release a blast of energy that fundamentally regulates galaxy evolution and black hole growth itself.
