We can't see them directly, but we know they're there. Supermassive black holes (SMBHs) likely dwell at the center of every large galaxy. Their overwhelming gravity draws material toward them, where it collects in an accretion ...

Black holes are like temperamental toddlers. They spill food all the time, but ESA's XMM-Newton has caught a black hole in the act of "flipping over the table" during an otherwise civilized meal.

Black holes are powerful gravitational engines. So you might imagine that there must be a way to extract energy from them given the chance, and you'd be right. Certainly, we could tap into all the heat and kinetic energy ...

Using a spectral synthesis code designed to simulate conditions in interstellar matter, astronomers have explored a faint tidal disruption event (TDE) designated iPTF16fnl. Results of the study, published Dec. 29 on the pre-print ...
Debris disks are quite common in the universe. Young stars have protoplanetary disks from which planets form. Black holes have accretion disks that are the source of the galactic jets. Supernova remnants can form a disk around ...
