We trace the evolution of off-centre massive black holes (MBHs) in dwarf galaxies using cosmological hydrodynamical simulations, and show that the …

WebbMilky Way (MW) satellites exhibit a diverse range of internal kinematics, reflecting in turn a diverse set of subhalo density profiles. These profiles include large cores and dense cusps, which any successful dark matter model must explain simultaneously. A plausible driver of such diversity is self-interactions between dark matter particles (SIDM) if the cross … Webb30 juni 2024 · These “seed” black holes would have been much massive than those typically formed by the collapse of ordinary gas—akin to the baby in the analogy being born already weighing 100 pounds. From there, it could grow through the “normal” process of eating nearby matter.
Webb18 nov. 2024 · A research team has reconstructed the origin of an unusual gravitational wave signal.

The story of how supermassive black holes were found began with the investigation by Maarten Schmidt of the radio source 3C 273 in 1963. Initially this was thought to be a star, but the spectrum proved puzzling. It was determined to be hydrogen emission lines that had been red shifted, indicating the object was moving away from the Earth. Hubble's law showed that the object was located several billion light-years away, and thus must be emitting the energy equivalent of hundr…
