When two black holes slam together, they do not simply vanish into darkness, they ring like struck bells and briefly light up ...

A detailed suite of simulations conducted by astrophysicists at the Flatiron Institute and their collaborators showed that magnetic fields can produce black holes with masses that were previously ...

A new study on some 1,600 galaxies based on data from the Chandra X-ray Observatory reveals that many small galaxies do not ...

In 2023, astronomers detected a huge collision. Two unprecedentedly massive black holes had crashed an estimated 7 billion light-years away. The enormous masses and extreme spins of the black holes ...

Astronomers usually detect black holes by looking for X-rays. When gas and dust fall toward a black hole, they heat up and ...

The James Webb Space Telescope has just confirmed a cosmic fugitive: the first known supermassive black hole racing through ...

In December 2019, an ordinary galaxy 300 million light-years from us in the constellation Virgo suddenly woke up. After decades of inactivity, the black hole at the galaxy's heart burst with light.

If a new proposal by physicists bears out, the recent detection of a record-setting neutrino could be the first evidence of elusive Hawking radiation. (Nanowerk News) The last gasp of a primordial ...

A comprehensive set of simulations by Flatiron Institute astrophysicists and their colleagues revealed that magnetic fields are responsible for creating black holes with masses in a range previously ...
