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…

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…

The implications of stochastic gas torques for asymmetric binaries in the LISA band
Lorenzo Copparoni, Lorenzo Speri, Laura Sberna +2
Gravitational waves from asymmetric mass-ratio black-hole binaries carry unique information about their astrophysical environment. For instance, the Laser Interferometer Space Ante…
