The origin of the first neutron star -- neutron star merger
K. Belczynski, A. Askar, M. Arca-Sedda +8
The first neutron star-neutron star (NS-NS) merger was discovered on August 17, 2017 through gravitational waves (GW170817) and followed with electromagnetic observations. This mer…
The MEGaN project II. Gravitational waves from intermediate mass- and binary black holes around a supermassive black hole
Manuel Arca-Sedda, Roberto Capuzzo-Dolcetta
We investigate the evolution of intermediate-mass (IMBHs), stellar (BHs) and binary black holes (BHBs), deposited near a supermassive black hole (SMBH) by a population of massive s…
Gamma-ray and X-ray emission from the Galactic Centre: hints on the nuclear star cluster formation history
Manuel Arca-Sedda, Bence Kocsis, Timothy Brandt
The Milky Way centre exhibits an intense flux in the gamma and X-ray bands, whose origin is partly ascribed to the possible presence of a large population of millisecond pulsars (M…
The MEGaN project I. Missing formation of massive nuclear clusters and tidal disruption events by star clusters - massive black hole interactions
Manuel Arca-Sedda, Roberto Capuzzo-Dolcetta
We investigated the evolution of a massive galactic nucleus hosting a super-massive black hole (SMBH) with mass surrounded by a population o…
