“Dark Hearts of the Cosmos” –Dazzling New Mergers of Black Holes and Neutron Stars

“Mergers of black holes with neutron stars are exceptionally rare in the Universe.  “An actual merger of a neutron star with a black hole happens, perhaps, once every million years in a galaxy.  To see one in the Milky Way, we would have to watch for a very long time,” Harald Pfeiffer, group leader in the Astrophysical and Cosmological Relativity department at Max Planck Institute for Gravitational Physics (AEI) in Potsdam, Germany, told The Daily Galaxy about recent neutron star-black hole merger of GW200105, detected by LIGO and Virgo in the past five years that have opened a completely new new way of observing the Universe.


“Pac-Man Black Hole Mergers” –Could Explain Origins of the Cosmic Web of Galaxies

“This could be a unique way of probing the physics around these supermassive black holes in a way that could not be probed in any other way,” said theoretical gravitational wave astrophysicist, Rochester Institute of Technology’s Assistant Professor Richard O’Shaughnessy, about simulations that could explain the origins of back hole mergers. “It offers unique insight into how the centers of galaxies grow, which is of course essential to understanding how galaxies as a whole grow, which explains most of the structure in the universe.”
