Black-hole - neutron-star mergers: new numerical-relativity simulations and multipolar effective-one-body model with spin precession and eccentricity
Alejandra Gonzalez, Sebastiano Bernuzzi, Alireza Rashti +2
In this paper, we present 52 new numerical-relativity (NR) simulations of black-hole-neutron-star merger (BHNS) mergers and employ the data to inform TEOBResumS-DalÃ: a multipolar…
Spin the black circle II: tidal heating and torquing of a rotating black hole by a test mass on generic orbits
Rossella Gamba, Danilo Chiaramello, Estuti Shukla +1
Horizon fluxes of energy and angular momentum are a key strong-field effect in the dynamics of black holes, encoding direct information about their nature. In this work, we present…
Simulations of Spinning Binary Black Hole Mergers
Estuti Shukla, Alireza Rashti, Rossella Gamba +2
We present the second release of the waveform catalog, comprising four new quasi-circular, non-precessing, spinning binary black hole simulations. These simu…
The Cost of Circularity: Quantifying Eccentricity-Induced Biases in Binary Black Hole Inference
Tamal RoyChowdhury, V. Gayathri, Rossella Gamba +3
Dynamically assembled binary black holes are expected to retain measurable orbital eccentricity in the LIGO-Virgo-KAGRA band, but most parameter estimation analyses still assume qu…
Kilohertz Gravitational Waves from Binary Neutron Star Mergers: Full Spectrum Analyses and High-density Constraints on Neutron Star Matter
Giulia Huez, Sebastiano Bernuzzi, Matteo Breschi +1
We demonstrate Bayesian analyses of the complete gravitational-wave spectrum of binary neutron star mergers events with the next-generation detector Einstein Telescope. Our mock an…
From Source Properties to Strong-Field Tests: a multipronged analysis of GW250114 with an effective one-body model for generic orbits
Koustav Chandra, Rossella Gamba, Danilo Chiaramello
We present a detailed analysis of GW250114, the loudest gravitational-wave signal observed to date, using a waveform model capable of describing binary black holes in generic (ecce…
