Scientists Identify Rare Black Hole Merger in the Early Universe Using Gravitational Mapping
Astronomers have identified two merging supermassive black hole systems named Gondor and Rohan using a new method combining quasars and gravitational wave background signals. The discovery offers a fresh way to map black hole mergers and understand galaxy evolution and cosmic gravitational waves in a clearer and more systematic manner.

Pulsar Observations Could Reveal Gravitational Wave Interference From Black Holes
A new study proposes detecting gravitational-wave “beats” using pulsar timing. Researchers from Hirosaki University suggest that interference between waves from supermassive black hole binaries could appear as periodic variations in pulsar signals. The method may help distinguish individual sources from a diffuse gravitational-wave background i...

Astronomers Observe Rare Supernova–Black Hole Interaction in Early Stages
In a groundbreaking discovery, astronomers observed SN 2023zkd, a supernova that may have been triggered by close interaction with a black hole. Featuring unusual brightness peaks and extended pre-explosion activity, the event offers new insights into star black hole dynamics. Real-time AI detection played a key role, and upcoming surveys promise t...

NASA’s IXPE Challenges Theories on Black Hole Corona and Polarised X-Ray Emissions
NASA’s Imaging X-ray Polarimetry Explorer (IXPE) has made surprising observations in a black hole binary system, detecting a high degree of X-ray polarisation that challenges current models of corona structure and accretion discs. In X-ray binaries, black holes pull matter from nearby stars, forming hot accretion discs and coronas.

Twisted Jet Confirms Most Extreme Binary Black Hole System in the Universe
Astronomers have confirmed that the blazar OJ 287 hosts the most extreme binary black hole system ever found. Using a global radio telescope array, they captured an ultra-sharp image showing a dramatically bent jet—evidence of two supermassive black holes locked in orbit. The system’s 12-year flare cycle and jet twists match predictions of a sm...

Supermassive Black Hole Flashed Twice in a Rare Event, Scientists Explain the Reason
In a galaxy 408 million light-years away, the black hole ASASSN-22ci consumed a star from a binary system, producing a rare double-flash tidal disruption event (TDE). First observed in February 2022, a second flare occurred 720 days later, possibly caused by Hills capture. Researchers anticipate a third flare in early 2026, offering unprecedented i...

Astronomers Seek Binary Supermassive Black Holes in Galactic Centers
Astronomers have detected possible binary black holes at the centres of galaxies, using light patterns from active galactic nuclei as key indicators. The study of PG 1553+153, in particular, shows evidence of a 20-year variation, pointing to a system of two supermassive black holes. If confirmed, this could provide new insights into galaxy formatio...

Binary Star System D9 Found Orbiting Sagittarius A* Near Milky Way’s Core
Astronomers have detected a young binary star system, D9, orbiting Sagittarius A*, the supermassive black hole at the Milky Way's centre. This challenges previous assumptions about star survival near intense gravitational forces. The discovery was made using the European Southern Observatory's Very Large Telescope. Future research with advanced tel...

NASA and JAXA’s XRISM Mission Captures Detailed Data from X-Ray Emitting Wolf-Rayet Star
NASA and JAXA’s XRISM mission recently produced a detailed analysis of Cygnus X-3, a high-mass binary system containing a Wolf-Rayet star and a likely black hole. Using high-resolution X-ray spectroscopy, scientists observed intricate gas dynamics involving the star’s stellar winds and interactions with its companion.

Twin Black Holes Spotted Feasting On Cosmic Materials
At the centre of two merging galaxies, two black holes have been observed devouring matter side by side, raising the possibility that binary black holes are more frequent than previously assumed.
