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…
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…
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…
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…
Hierarchical modeling of gravitational-wave populations for disentangling environmental and modified-gravity effects
Shubham Kejriwal, Enrico Barausse, Alvin J. K. Chua
The upcoming Laser Interferometer Space Antenna (LISA) will detect up to thousands of extreme-mass-ratio inspirals (EMRIs). These sources will spend cycles in band, and…
When vacuum breaks: a self-consistency test for astrophysical environments in extreme mass ratio inspirals
Lorenzo Copparoni, Rohit S. Chandramouli, Enrico Barausse
Gravitational-wave signals are typically interpreted under the vacuum hypothesis, i.e. assuming negligible influence from the astrophysical environment. This assumption is expected…
Muffled Murmurs: Environmental effects in the LISA stochastic signal from stellar-mass black hole binaries
Ran Chen, Rohit S. Chandramouli, Federico Pozzoli +2
The population of unresolved stellar-mass black hole binaries (sBBHs) is expected to produce a stochastic gravitational-wave background (SGWB) potentially detectable by the Laser I…
Systematic bias in LISA ringdown analysis due to waveform inaccuracy
Lodovico Capuano, Massimo Vaglio, Rohit S. Chandramouli +3
Inaccurate modeling of gravitational-wave signals can introduce systematic biases in the inferred source parameters. As detector sensitivities improve and signals become louder, mi…
Reconstructing the LISA massive black hole binary population via iterative kernel density estimation
Jam Sadiq, Kallol Dey, Thomas Dent +1
Reconstructing the properties of the astrophysical population of binary compact objects in the universe is a key science goal of gravitational wave detectors. This goal is hindered…
