Chaotic migration of LISA Extreme Mass Ratio Inspirals in a turbulent accretion disk: effect on waveform de-phasing
Mudit Garg, Lucio Mayer, Yinhao Wu +2
Gravitational wave (GW) detector LISA will observe near-coalescence extreme mass ratio inspirals (EMRIs), which typically form in galactic central accretion disks. Gas torques on E…
A practical theorem on gravitational-wave background statistics
Yacine Ali-Haïmoud
Inspiralling supermassive black-hole binaries (SMBHBs) are expected to be the main source of the nanohertz gravitational-wave background (GWB) targeted by pulsar timing arrays (PTA…
Addressing leakage and mode suppression in angular power spectrum estimation for gravitational-wave backgrounds using pulsar timing arrays
Deepali Agarwal, Joseph D. Romano, Yacine Ali-Haïmoud +1
Mapping gravitational-wave background (GWB) anisotropy with pulsar timing arrays (PTAs) is affected by harmonic-space mode suppression and mode coupling arising from an array's non…
Efficient analytic approximation for small-scale non-cold relic perturbations
Nanoom Lee, Yacine Ali-Haïmoud, Marc Kamionkowski
We develop a highly accurate analytic approximation for small-scale non-cold relic perturbations by solving the collisionless Boltzmann equation in the quasi-stationary regime. The…
