Bekenstein-Hod Universal Bound on Information Emission Rate Is Obeyed by LIGO-Virgo Binary Black Hole Remnants

no code implementations10 Mar 2021 Gregorio Carullo, Danny Laghi, John Veitch, Walter Del Pozzo

Causality and the generalized laws of black hole thermodynamics imply a bound, known as the \textit{Bekenstein--Hod universal bound}, on the information emission rate of a perturbed system.

AT2017gfo: Bayesian inference and model selection of multi-component kilonovae and constraints on the neutron star equation of state

no code implementations4 Jan 2021 Matteo Breschi, Albino Perego, Sebastiano Bernuzzi, Walter Del Pozzo, Vsevolod Nedora, David Radice, Diego Vescovi

The joint detection of the gravitational wave GW170817, of the short $\gamma$-ray burst GRB170817A and of the kilonova AT2017gfo, generated by the the binary neutron star merger observed on August 17, 2017, is a milestone in multimessenger astronomy and provides new constraints on the neutron star equation of state.

Dirichlet Process Gaussian-mixture model: An application to localizing coalescing binary neutron stars with gravitational-wave observations

1 code implementation24 Jan 2018 Walter Del Pozzo, Christopher Berry, Archisman Ghosh, Tom Haines, Leo Singer, Alberto Vecchio

We reconstruct posterior distributions for the position (sky area and distance) of a simulated set of binary neutron-star gravitational-waves signals observed with Advanced LIGO and Advanced Virgo.
