| Abstract: |
Black hole masses are tightly correlated with the stellar velocity dispersion σ of host galaxies, and slightly less-well correlated with the bulge luminosities L. The M•-σ relation predicts fewer massive black holes than does the M•-L relation. This is because the L-σ in black hole samples currently available is inconsistent with that in the samples from which the distributions of L or σ are based. This suggests that current black hole samples are biased and that the M•-σ and M•-L relations currently in the literature are also biased from their intrinsic values. Our analysis suggests that the bias in the M•-σ relation is likely to be small, whereas the M•-L relation is biased towards predicting more massive black holes for a given luminosity. |
