Every massive galaxy is believed to host a supermassive black hole (SMBH) at its center. Its mass is correlated with the mass of the inner regions of its host (and also with some other properties), probably because the SMBH ...

At the center of galaxies, like our own Milky Way, lie massive black holes surrounded by spinning gas. Some shine brightly, with a continuous supply of fuel, while others go dormant for millions of years, only to reawaken ...

Using the Keck I telescope, Japanese astronomers have identified a massive quiescent galaxy in a distant galaxy protocluster known as SSA22. The galaxy, designated ADF22-QG1, turns out to be the most distant quiescent galaxy ...
At the heart of almost every sufficiently massive galaxy there is a black hole whose gravitational field, although very intense, affects only a small region around the center of the galaxy. Even though these objects are thousands ...
