Scientists supported by the National Science Foundation (NSF) recently announced the detection of the merger of two relatively "light" black holes, 7 and 12 times the mass of the sun, respectively, at...
Supermassive black holes lurk at the centers of many galaxies. While some — like the black hole at the center of our own Galaxy — live quiet lives, occasionally snacking on a star or two, others feed ...
A team of astronomers, including two from MIT, has detected the most distant supermassive black hole ever observed. The black hole sits in the center of an ultrabright quasar, the light of which was e...
For the first time, scientists worldwide and at Penn State University have detected both gravitational waves and light shooting toward our planet from one massively powerful event in space -- the birt...
In August, detectors on two continents recorded gravitational wave signals from a pair of black holes colliding. This discovery, announced today, is the first observation of gravitational waves by thr...
Statement from National Science Foundation (NSF) Director France Córdova regarding news that researchers at the Laser Interferometer Gravitational-wave Observatory (LIGO) detected gravitational waves ...
Rochester Institute of Technology researchers continue to make significant contributions to gravitational wave astronomy, with the third detection of gravitational waves and a new black hole 49 times ...
Supermassive black holes, millions to billions of times the mass of our Sun, are found at the centers of galaxies. Many of these galactic behemoths are hidden within a thick doughnut-shape ring of dus...
Roughly 90 percent of the biggest black holes in the known universe are dormant, meaning that they are not actively devouring matter and, consequently, not giving off any light or other radiation. But...
Astronomers using the 8-meter Gemini North telescope on Hawaii’s Maunakea have probed an enigmatic, and unexpected, supermassive black hole dominating the core of a large galaxy in the cosmic backwate...
New research led by astrophysicists at York University has revealed the fastest winds ever seen at ultraviolet wavelengths near a supermassive black hole.“We’re talking wind speeds of 20 per cent the ...
Black holes are the subject of much fascination, not just in science but also in popular media. For example, the 2014 movie “Interstellar” portrays a fast-rotating, supermassive black hole, into which...
Most people think of black holes as giant vacuum cleaners sucking in everything that gets too close. But the supermassive black holes at the centers of galaxies are more like cosmic engines, convertin...
Radiation from a narrow circular ring shows a characteristic double-horn profile dominated by photons having energy around the maximum or minimum of the allowed range, i.e. near the extremal values of...
A new empirical formulae is given for estimating the masses of black holes in AGNs from the H beta velocity dispersion and the continuum luminosity at 5100 Angstroms. It is calibrated to reverberation...
