Renormalized spin coefficients in the accumulated orbital phase for unequal mass black hole binaries

László Á. Gergely, Peter L. Biermann, Balázs Mikóczi +1

We analyze galactic black hole mergers and their emitted gravitational waves. Such mergers have typically unequal masses with mass ratio of the order 1/10. The emitted gravitationa…

On the detectability of primordial black holes in the Galaxy

Julia K. Becker, Marek A. Abramowicz, Peter L. Biermann

In the mass range of 1e15 g up to 1e26 g, primordial black holes (PBHs) as a possible contribution to the dark matter are still unexplored. In this contribution, we investigate the…
