A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen object called a black hole pulsar.

In 2007, I published a single-authored paper in the prestigious journal Physical Review Letters, suggesting that a gravitational-wave recoil could displace a black hole from the galactic center and ...

NASA finds supermassive black hole called ‘Space Jaws:’ Why it deserves sci-fi horror name A sneaky black hole was the source of a tidal disruption event that was so large and so bright that ...

Astronomers have spotted an apparent supermassive black hole snacking on a star 600 million light-years away, wandering through a galaxy with an even larger black hole at its core. The event ...

A black hole skulking in the shadows 600 million light-years away in space gave itself away with a dazzling flash, the light of a star it had just gnashed and eaten. Using NASA 's Hubble Space ...

Initially, as the marauding black hole moved through the universe, it was detectable only through gravitational lensing—an effect caused by the black hole’s gravity distorting visible light in a way ...

That’s the first optically discovered off-nuclear TDE discovered.” A six-panel illustration of a tidal disruption event around a supermassive black hole. NASA, ESA, STScI, Ralf Crawford (STScI) ...

The rest are associated with the central black holes of galaxies. In fact, at the center of the host galaxy there is a different supermassive black hole weighing 100 million times the mass of the sun.

This supermassive black hole was discovered thanks to the newly-identified tidal disruption event AT2024tvd, an astronomical phenomenon in which a star passes too close to a black hole and the extreme ...

For years, researchers have studied how these QNMs behave when a black hole's parameters change. While a lot of progress has been made, some strange behaviors in the QNM patterns remained unexplained.
