The process occurs in active-core nuclei. A molecular gas cloud that accumulates in the central region is blown away by radiation from the black hole’s…
A binary black hole merger likely produced gravitational waves equal to the energy of eight suns. For all its vast emptiness, the universe is humming…
Scientists Detect First-of-Its-Kind ‘Intermediate-Mass’ Black Hole An international research collaboration including Northwestern University astronomers has witnessed the birth of an “intermediate-mass” black hole. This is…
Radio astronomers have detected jets of hot gas blasted out by a black hole in the galaxy at the heart of the Phoenix Galaxy Cluster,…
First clear confirmation of accretion disk formation in a tidal disruption event without x-ray emissions supports theoretical predictions. When a star passes too close to…
Until now, these flows of material had been detected only in other wavelength ranges, such as X-rays or the visible, depending on the phase in…
A new letter has been found in the mysterious alphabet of black holes. Two astrophysicists share this discovery in the journal Nature Communications. Black holes…
Cosmic gas cloud blinks in sync with circling black hole. Scientists have detected a mysterious gamma-ray heartbeat coming from a cosmic gas cloud. The inconspicuous…
A new study reveals what happens when a supermassive black hole in the center of a galaxy cluster stops being active. By combining data from…
Astronomers have discovered what can happen when a giant black hole does not intervene in the life of a galaxy cluster. Using NASA’s Chandra X-ray…
Scientists from the University of Valencia detect rapid changes in a black hole that may help understand the origin of gamma-ray bursts. A team from…
The telltale sign that the black hole was feeding vanished, perhaps when a star interrupted the feast. The event could lend new insight into these…
The second most distant quasar ever discovered now has a Hawaiian name. Astronomers have discovered the second most distant quasar ever found, using the international…
A simple model explains a wide range of observations by describing a contest between galaxy halos and their central black holes that eventually turns off…
A colliding star may have triggered the drastic transformation. It seems the universe has an odd sense of humor. While a crown-encrusted virus has run…
Scientists at Harvard University and the Black Hole Initiative (BHI) have developed a new method to find black holes in the outer solar system, and…
Astronomers zoom in on black hole with one of the lowest masses ever observed in nearby “ghost” galaxy. A research team led by Cardiff University…
