The first four LIGO detections have confirmed the existence of massive black holes (BHs), with mass 30-40 M-circle dot. Such BHs might originate from massive metal-poor stars (Z < 0.3 Z(circle dot)) or from gravitational instabilities in the early Universe. The formation channels of merging BHs are still poorly constrained. The measure of mass, spin and redshift distribution of merging BHs will give us fundamental clues to distinguish between different models. In parallel, a better understanding of several astrophysical processes (e.g. common envelope, core-collapse SNe, and dynamical evolution of BHs) is decisive, to shed light on the formation channels of merging BHs.
