A new form of black hole archeology, linking spin to gas and dust, has revealed that these cosmic titans spin faster than ...

Astronomers have been monitoring the black hole for years, primarily since 2018 when the mass was observed changing its properties with a major X-ray outburst. Between 2022 and 2024, astronomers ...

"Our measurements imply that the supermassive black hole mass is 10% of the stellar mass in the galaxies we studied." Using the James Webb Space Telescope (JWST), astronomers have discovered ...

Expect the unexpected In this artist’s rendering, a stream of matter trails a white dwarf orbiting within the innermost accretion disk surrounding 1ES 1927+654’s supermassive black hole. (Courtesy: ...

・Holmberg 15A: The central galaxy of the Abell 85 cluster contains a black hole with a mass of approximately 40 billion solar masses. ・S5 0014+81: This blazar's central black hole is estimated ...

Black holes and their archaeology The results of the SDSS Survey of mass measurements of hundreds of black holes were a surprise, according to Fries. That's because the spin rates reveal something ...

An international team found dark matter dominating the halos of two supermassive black holes in galaxies 13 billion light ...

(For a quasar-powering supermassive black hole, that is. It still has a mass equivalent to 450 million suns). Credit: NOIRLab/NSF/AURA/M. Garlick "Interestingly, the quasar powering this massive ...

"Black holes seem so exotic, but you can describe them completely with just two numbers: mass and spin rate," Fries explained. "The problem is that mass is hard to measure, and spin is even harder." ...
