Physicists from the University of Nottingham and the University of Cambridge have for the first time demonstrated that the evolution of black holes resulting...
Gravitational-wave detectors can be used to measure gravitational-field hair of extreme black holes, according to a paper published in the journal Physical...
If ‘stupendously large’ black holes, those with masses more than 100 billion times that of the Sun, exist in the Universe, they would provide a powerful...
Spinning black holes store rotational energy that can be extracted; when a black hole is immersed in an externally supplied magnetic field, reconnection...
An active galactic nucleus in the center of ESO 253-G003, an active galaxy over 570 million light-years away in the southern constellation of Pictor, erupts...
Whenever two compact objects (black holes or neutron stars) collide elsewhere in the Universe, they create gravitational waves that travel across space,...
In a new paper in the journal Physical Review Letters, an international team of theoretical physicists described a scenario for the formation of primordial...
Using ESO’s Very Large Telescope (VLT) and New Technology Telescope (NTT), the Las Cumbres Observatory global telescope network, and NASA’s Neil Gehrel...
The 2017 observations from the Event Horizon Telescope (EHT) of M87*, a 6.5-billion-solar-mass black hole in the center of the giant elliptical galaxy...
Using the MUSE and FORS2 instruments on ESO’s Very Large Telescope (VLT), astronomers have spotted a group of six galaxies around SDSS J1030+0524, a...
In 2019, the Event Horizon Telescope (EHT) delivered the first resolved images of M87*, the supermassive black hole in the center of the giant elliptical...
An analysis of archival X-ray data from NASA’s Rossi X-Ray Timing Explorer has revealed a clear separation between the characteristics of stellar-mass...
Astronomers using the twin LIGO detectors located in Livingston, Louisiana, and Hanford, Washington, and the Virgo detector located near Pisa, Italy, have...
An international team of astronomers has watched as an X-ray corona of a supermassive black hole in the active galactic nucleus 1ES 1927+654 was abruptly...
Amir Siraj and Professor Avi Loeb from the Department of Astronomy at Harvard University have developed a new method to search for primordial black holes...
Using the X-SHOOTER and the ESPRESSO (Echelle Spectrograph for Rocky Exoplanet- and Stable Spectroscopic Observation) instruments on ESO’s Very Large...
An international team of astronomers has discovered the second most distant quasar ever found. Named Pōniuā`ena and designated J100758.264+211529.207...
The gravitational-wave signal GW190814, detected on August 14, 2019 by NSF’s Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo...
Physicists from the University of Glasgow and the University of Arizona have experimentally verified a half-century-old theory that began as speculation...
A new all-sky image from the eROSITA X-ray telescope onboard the Spectrum-Roentgen-Gamma (SRG) space observatory contains over one million objects, about...
