Probing $z\gtrsim 6$ massive black holes with gravitational waves

Srija Chakraborty, Simona Gallerani, Tommaso Zana +6

We investigate the coalescence of massive black hole ($M_{\mathrm{BH}}\gtrsim 10^6{\mathrm{M}}_{\odot }$) binaries (MBHBs) at $6<z<10$ by adopting a suite of cosmological hydrodynamical simu…
