When vacuum breaks: a self-consistency test for astrophysical environments in extreme mass ratio inspirals
Lorenzo Copparoni, Rohit S. Chandramouli, Enrico Barausse
The paper introduces a non‑parametric self‑consistency test that checks whether gravitational‑wave parameter estimates from different parts of an extreme mass ratio inspiral signal…
Environmental effects vs. modified gravity in the LISA massive black hole binary population
Lorenzo Copparoni, Enrico Barausse
Gravitational-wave signals from massive black hole binaries observed by LISA can carry imprints of both the astrophysical environment of the source and possible deviations from gen…
Impact of sky localization uncertainty on ringdown inference
Kallol Dey, Enrico Barausse, Marco Crisostomi +1
As gravitational-wave ringdown signals grow louder, quasinormal-mode inference depends increasingly on the treatment of extrinsic parameters. Standard analyses fix sky localization…
Implications of the LISA stochastic signal from eccentric stellar mass black hole binaries in vacuum
Ran Chen, Rohit S. Chandramouli, Federico Pozzoli +2
Astrophysical formation channels of stellar-mass binary black holes (sBBHs) can induce significant orbital eccentricities in their early inspiral. We analyze the implications on th…
Constraints on Einstein-aether gravity from the precision timing of PSR J1738+0333
Massimo Vaglio, Amodio Carleo, Abhimanyu Susobhanan +5
We constrain Einstein-aether gravity -- a Lorentz-violating extension of General Relativity in which a dynamical, unit timelike vector field selects a preferred frame -- using upda…
Scalar emission from binary neutron stars in scalar-tensor theories with kinetic screening
Ramiro Cayuso, Adrien Kuntz, Thiago Assumpcao +2
We investigate the scalar emission from binary neutron stars in shift-symmetric scalar-tensor theories with kinetic screening (-essence), using 3+1 numerical simulations in the…
