Webb2 sep. 2024 · Stellar-class black holes are typically created when a large star runs out of its nuclear fuel and the churning engine of light and heat stops. Without that outward pressure, the star's outer layers collapse under gravity, triggering a colossal supernova and leaving behind a black hole. WebbThe majority of massive black holes (MBHs) likely hosted gas discs during their lifetimes. These could either be long-lived active galactic nuclei (AGN) discs, or shorter-lived discs formed following singular gas infall events, as was likely the case in our own Galactic Center. Stars and compact objects in such environments are therefore expected to … WebbMassive black holes (MBHs) inhabit galactic centres, and power luminous quasars and active galactic nuclei, shaping their cosmic environment with the energy they produce. The origins of MBHs remain a mystery, and the recent detection by LIGO/Virgo of a black hole of almost 150 solar masses has revitalized the questions of whether there is a … بیوگرافی جواد خیابانی و خانواده اش
