Abstract 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 findings of Vitale et al. (2017) and show additional marginalized posterior distributions for some of the binaries’ intrinsic parameters. These findings were presented at IAU Symposium 338, held on October 16-19, 2017 in Baton Rouge, LA, USA.

- 2020

Public GW190412 LIGO/Virgo data is analyzed with a Bayesian prior where the more massive black hole resulted from a previous merger and it is found that this interpretation is equally supported by the data.

This work reanalyze the first detections performed by the twin LIGO interferometers using alternative (and astrophysically motivated) prior assumptions and finds different prior distributions can introduce deviations in the resulting posteriors that impact the physical interpretation of these systems.

The properties of precessing, coalescing binary black holes are presently inferred through comparison with
two approximate models of compact binary coalescence. In this work we show that these two…

The magnitude of modifications to the gravitational-wave dispersion relation is constrain, the graviton mass is bound to m_{g}≤7.7×10^{-23} eV/c^{2} and null tests of general relativity are performed, finding that GW170104 is consistent with general relativity.

The association of GRB 170817A, detected by Fermi-GBM 1.7 s after the coalescence, corroborates the hypothesis of a neutron star merger and provides the first direct evidence of a link between these mergers and short γ-ray bursts.
