Reanalysis of LIGO black-hole coalescences with alternative prior assumptions
Davide Gerosa, Salvatore Vitale, Carl-Johan Haster +2
We present a critical reanalysis of the black-hole binary coalescences detected during LIGO's first observing run under different Bayesian prior assumptions. We summarize the main…
Surprises from the spins: astrophysics and relativity with detections of spinning black-hole mergers
Davide Gerosa
Measurements of black-hole spins are of crucial importance to fulfill the promise of gravitational-wave astronomy. On the astrophysics side, spins are perhaps the cleanest indicato…
Long-lived inverse chirp signals from core collapse in massive scalar-tensor gravity
Ulrich Sperhake, Christopher J. Moore, Roxana Rosca +3
This letter considers stellar core collapse in massive scalar--tensor theories of gravity. The presence of a mass term for the scalar field allows for dramatic increases in the rad…
Impact of Bayesian prior on the characterization of binary black hole coalescences
Salvatore Vitale, Davide Gerosa, Carl-Johan Haster +2
In a regime where data are only mildly informative, prior choices can play a significant role in Bayesian statistical inference, potentially affecting the inferred physics. We show…
Nutational resonances, transitional precession, and precession-averaged evolution in binary black-hole systems
Xinyu Zhao, Michael Kesden, Davide Gerosa
In the post-Newtonian (PN) regime, the timescale on which the spins of binary black holes precess is much shorter than the radiation-reaction timescale on which the black holes ins…
Inferences about supernova physics from gravitational-wave measurements: GW151226 spin misalignment as an indicator of strong black-hole natal kicks
Richard O'Shaughnessy, Davide Gerosa, Daniel Wysocki
The inferred parameters of the binary black hole GW151226 are consistent with nonzero spin for the most massive black hole, misaligned from the binary's orbital angular momentum. I…
