The newly-discovered intermediate-mass black hole, named NGC 6099 HLX-1, resides in a compact star cluster on the outskirts of the elliptical galaxy NGC...
This supermassive black hole was discovered thanks to the newly-identified tidal disruption event AT2024tvd, an astronomical phenomenon in which a star...
A tidal disruption event occurs when a star winds up so close to a supermassive black hole that the tidal forces exceed the star’s self-gravity and shred...
Astronomers using NASA’s Chandra X-ray Observatory, ESA’s XMM-Newton and other telescopes have found evidence for a massive stellar disruption (over...
Intermediate-mass black holes in the mass range between 100 and 100,000 solar masses are the missing link between stellar-mass black holes and super massive...
The intermediate-mass black hole in question was caught in the act of swallowing a star, called a tidal disruption event. Dubbed 3XMM J215022.4-055108,...
The majority of supermassive black holes lie dormant and starved of fuel; these hidden giants can be temporarily illuminated when an unlucky star passes...
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...
Astronomers using the NASA/ESA Hubble Space Telescope have detected tidal tails in NGC 1052-DF4, a dark-matter-deficient galaxy some 65 million light-years...
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 Phoenix stellar stream, a thin over-density of stars in the halo of our Milky Way Galaxy originally identified by the Dark Energy Survey, is composed...
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...
Professor Andrew King from the University of Leicester has shown that periodic X-ray eruptions from a galaxy called GSN 069 could result from the core...
A due of researchers used numerical simulations to show that interstellar objects like ‘Oumuamua, a fast moving, cigar-shaped object of extrasolar origin...
A bright X-ray source in a massive star cluster in the outskirts of 6dFGS gJ215022.2-055059, a barred lenticular galaxy located about 806 million light-years...
NASA’s Transiting Exoplanet Survey Satellite (TESS) gave astronomers an unexpected glimpse at a black hole violently ripping apart a Sun-sized star....
A team of astrophysicists from Columbia University proposes that the strange long-term dimming of the KIC 8462852 star (also known as Tabby’s star or...
A multinational group of astronomers has imaged the formation and expansion of a fast-moving jet of material ejected when the intense gravity of a supermassive...
