Conditions favorable for gravitational wave-emitting mergers of massive black holes exist in the outer gas disks of big spiral galaxies, according to a...
At the center of our Milky Way Galaxy lies the 4-million-solar-mass black hole named Sagittarius A*. This gravitational monster is surrounded by a group...
When two galaxies collide, their central supermassive black holes also smash together. But before they do, these galaxies often flicker on, absorbing huge...
A new study using X-ray data from NASA’s Chandra X-ray Observatory indicates that the neutron star merger that became the gravitational wave source,...
A supermassive black hole in the center of the ultra-luminous quasar SMSS J215728.21-360215.1 (J2157-3602 for short) devours a mass equivalent to our Sun...
In a new study, a team of astronomers from Yale Center for Astronomy & Astrophysics, the University of Washington, Institut d’Astrophysique de Paris,...
NGC 6240 is a pair of merging galaxies approximately 400 million light-years away in the constellation Ophiuchus. It spans 300,000 light-years and has...
Astronomers using NASA’s Chandra X-ray Observatory have discovered what they believe are 12 stellar-mass black holes gathered around Sagittarius A*,...
Astronomers have detected radio echoes of a supermassive black hole feeding on a star, suggesting the black hole emits a jet of energy proportional to...
Using NASA’s Chandra X-ray Observatory, astronomers have found evidence for what is likely the most massive black holes ever detected.
A massive black...
High resolution observations using the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed the presence of a rotating dusty gaseous torus...
A team of astronomers led by University of Colorado Boulder scientists has discovered a mechanism that explains the persistence of asymmetrical star clusters...
An international team of physicists has created the first small-scale replica of gamma ray bursts in a laboratory, opening up a whole new way to investigate...
An international team of astronomers led by Georg-August-Universität Göttingen researcher Benjamin Giesers has discovered a star in the globular cluster...
Using the Arecibo Observatory in Puerto Rico and the Green Bank Telescope in West Virginia, astronomers have gained new insight into the extreme home of...
Supermassive black holes, with masses more than a million times that of the Sun, reside at the centers of all massive galaxies. A new study published in...
A sudden flare from a low-mass black hole in the binary system V404 Cygni has offered astrophysicists a unique opportunity to make precise measurements...
