Massive black hole (BH) mergers are predicted to be powerful sources of
low-frequency gravitational waves (GWs). Coupling the detection of GWs with an electromagnetic (EM) detection can provide key information. Another important question is how the astrophysical information extracted from BH mergers can inform us about BH evolution. We analyse the high-resolution cosmological radiation-hydrodynamics simulation Obelisk, run to redshift z=3.5, to study the properties of the merging BH population, its differences with the underlying global BH population in terms of BH and galaxy properties, and its detectability in GW and EM domains, modelling spectral energy distribution and obscuration. |
