AGN as potential factories for eccentric black hole mergers [PDF]

Nature, 2020
There is some weak evidence that the black hole merger named GW190521 had a non-zero eccentricity1,2. In addition, the masses of the component black holes exceeded the limit predicted by stellar evolution3. The large masses can be explained by successive

Black Hole Genealogy: Identifying Hierarchical Mergers with Gravitational Waves [PDF]

Astrophysical Journal, 2020
In dense stellar environments, the merger products of binary black hole mergers may undergo additional mergers. These hierarchical mergers are naturally expected to have higher masses than the first generation of black holes made from stars.

Eccentric Black Hole Mergers in Active Galactic Nuclei [PDF]

Astrophysical Journal, 2020
The astrophysical origin of gravitational wave transients is a timely open question in the wake of discoveries by the Laser Interferometer Gravitational-Wave Observatory (LIGO)/Virgo. In active galactic nuclei (AGNs), binaries form and evolve efficiently

Merger Failures [PDF]

SSRN Electronic Journal, 2005
This paper proposes an explanation as to why some mergers fail, based on the interaction between the pre‐ and post‐merger processes. We argue that failure may stem from informational asymmetries arising from the pre‐merger period, and problems of cooperation and coordination within recently merged firms.
