Radiatively inefficient accretion flows induced by gravitational-wave emission before massive black hole coalescence

open access: yes, 2010
We study an accretion flow during the gravitational-wave driven evolution of binary massive black holes. After the binary orbit decays due to an interaction with a massive circumbinary disk, the binary is decoupled from the circumbinary disk because the ...

The distribution and cosmic evolution of massive black hole spins

open access: yes, 2004
We study the expected distribution of massive black hole (MBH) spins and its evolution with cosmic time in the context of hierarchical galaxy formation theories. Our model uses Monte Carlo realizations of the merger hierarchy in a LCDM cosmology, coupled
