Abstract (from CDS):

The recent LIGO detection of gravitational waves (GW150914), likely originating from the merger of two ∼ 30M☉ black holes suggests progenitor stars of low metallicity ([Z/Z☉] <= 0.3), constraining when and where the progenitor of GW150914 may have formed. We combine estimates of galaxy properties (star-forming gas metallicity, star formation rate and merger rate) across cosmic time to predict the low redshift black hole - black hole merger rate as a function of present day host galaxy mass, Mgal, the formation redshift of the progenitor system zf and different progenitor metallicities Zp. For Zp 0.1 Z_☉_, the signal is dominated by binaries in massive galaxies with zf ≃ 2 while below Zp 0.1 Z_☉_ most mergers come from binaries formed around zf ≃ 0.5 in dwarf galaxies. Additional gravitational wave detections from merging massive black holes will provide constraints on the mass-metallicity relation and massive star formation at high redshifts.
