Astronomical black holes are compact astrophysical systems characterized by regions of spacetime where gravity is so strong that no matter or radiation can escape beyond the event horizon. They are described by solutions to Einstein’s field equations, typically approximated by the Kerr or Schwarzschild metrics, and are defined by mass, spin, and (negligible) charge. Formed primarily via stellar core collapse or hierarchical mergers, they interact with their environments through accretion disks, relativistic jets, and gravitational-wave emission. Astronomical black holes span stellar-mass to supermassive regimes, influencing galactic dynamics, high-energy radiation processes, and cosmological structure formation.
Using observations from multiple powerful telescopes, a team of astronomers studied a red quasar nicknamed "the Hatchling" at redshift 3.7. They may have identified one of the clearest examples yet of a quasar caught in transition ...
Data released by the Sloan Digital Sky Survey (SDSS) marks a landmark expansion in the study of accreting supermassive black holes (SMBHs). As part of the fifth generation of the survey (SDSS-V), the Black Hole Mapper (BHM) ...

So far, almost all stellar-mass black holes detected by astronomers have been found in binary systems. However, astronomers have long suspected that these binary black holes are the exception and that, within the Milky Way, ...
Black holes are often portrayed as cosmic gluttons that swallow everything that comes too close. But new observations of a dramatic black hole outburst—led by Warwick Postdoctoral Fellow Dr. Noel Castro Segura—suggest the ...

Astronomers using the James Webb Space Telescope have captured one of the clearest views yet of how an early supermassive black hole may grow within a network of young galaxies. The compact active galaxy, seen just a billion ...
A black hole may be stirring a "pot" of gas containing a neighboring galaxy in the early universe, according to a new study published in Astronomy & Astrophysics that used observations from NASA's Chandra X-ray Observatory. ...

For decades, astronomers have cast galaxy mergers as the universe's ultimate relationship drama: two galaxies collide, chaos erupts, black holes awaken and star formation comes to a screeching halt. Upending this long-held ...
