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…
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…
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…
