    Scientists find a Common Thread Linking Subatomic Color Glass Condensate and Massive Black Holes

    March 22, 2023, Categories  Astronomy/Space

    Black holes with dimensions of billions of kilometers (left, as imaged by the Event Horizon Telescope) share features with a dense state of subatomic gluons created in collisions of atomic nuclei (right).

    Physicists show that black holes and dense state of gluons–the ‘glue’ particles that hold nuclear matter together–share common features. Atomic nuclei accelerated close to the speed of light become dense walls of gluons known as color glass condensate (CGC). Recent analysis shows that CGC shares features with black holes, enormous conglomerates of gravitons that exert gravitational force across the universe...

    Cracking a Mystery of Massive Black Holes and Quasars with Supercomputer Simulations

    Distribution of gas across scales, with the gas density increasing from purple to yellow. The top left panel shows a large region containing tens of galaxies (6 million light-years across). Subsequent panels zoom in progressively into the nuclear region of the most massive galaxy and down to the vicinity of the central supermassive black hole. Gas clumps and filaments fall from the inner edge of the central cavity occasionally feeding the black hole. Credit: Anglés-Alcázar et al. 2021, ApJ, 917, 53.

    Birth of Massive Black Holes in the Early Universe

    January 24, 2019, Categories  Astronomy/Space

    A 30,000 light-year region from the Renaissance Simulation centered on a cluster of young galaxies that generate radiation (white) and metals (green) while heating the surrounding gas. A dark matter halo just outside this heated region forms three supermassive stars (inset) each over 1,000 times the mass of our sun that will quickly collapse into massive black holes and eventually supermassive black holes over billions of years.
