An international team of astronomers has inspected long-term evolution of quasi-periodic eruptions (QPEs) from a QPE source designated eRO-QPE2. The study found that QPEs from this source are ...

For the first time, astronomers have probed the physical environment of repeating X-ray outbursts near monster black holes thanks to data from NASA's NICER (Neutron star Interior Composition Explorer) ...

A supermassive black hole 300 million light-years away has astrophysicists stumped. It lurks at the center of a galaxy called SDSS1335+0728, and, since 2019, researchers have been watching in ...

Strange X-ray pulses blasted out from a recently awakened monster black hole are the most powerful astronomers have seen, and may help explain how these cosmic behemoths emerge from their slumber. A ...

Astronomers have probed the physical environment of repeating X-ray outbursts near monster black holes thanks to data from NASA's NICER (Neutron star Interior Composition Explorer) and other missions.

Tidal disruption events occur when a star ventures sufficiently close to a supermassive black hole that differential gravitational forces overcome its self-gravity, shredding the star into streams of ...

A system astronomers call Ansky, in the galaxy at the center of this image, is home to a recently discovered series of quasi-periodic eruptions. For the first time, astronomers have probed the ...
