Dark matter could have helped make supermassive black holes in the early universe
Los Angeles CA (SPX) Sep 01, 2024 It takes a long time for supermassive black holes, like the one at the center of our Milky Way galaxy, to form. Typically, the birth of a black hole requires a giant star with the mass of at least 50 of our suns to burn out - a process that can take a billion years - and its core to collapse in on itself. Even so, at only about 10 solar masses, the resulting black hole is a far cry from the 4 million-solar-masses black hole, Sagittarius A', found in our Milky Way galaxy, or the billion-solar-mass ... read more |

Astronomers Track Star's Repeated Encounters with Supermassive Black Hole
Los Angeles CA (SPX) Aug 15, 2024 Using data from NASA's Chandra X-ray Observatory, the Neil Gehrels Swift Observatory, and ESA's XMM-Newton, researchers have gained significant insights into the timing and process of how a supermassive black hole consumes material, as detailed in a recent study. An artist's impression illustrates a star being partially disrupted by a black hole in the system known as AT2018fyk. This black hole, approximately 50 million times more massive than the sun, is located at the center of a galaxy around 8 ... read more
