An explicit and differentiable Wilson-Daubechies-Meyer transform for gravitational-wave data analysis
Avi Vajpeyi, Giorgio Mentasti, Quentin Baghi +2
The Wilson-Daubechies-Meyer (WDM) time-frequency transform has been widely used in gravitational-wave astronomy, yet a self-contained, mathematically explicit reference for practit…
Sachs-Wolfe effect as a smoking gun for cosmological gravitational wave backgrounds
Giorgio Mentasti, Leon Vidal, Quentin Baghi +1
The Sachs-Wolfe (SW) effect, arising from large-scale structures in the universe, modifies the frequencies of gravitational waves (GWs) sourced by a cosmological background. We sho…
The Doppler effect of the Milky Way rotation on LISA
Giorgio Mentasti, Quentin Baghi
The galactic background of gravitational waves (GWs) is expected to be anisotropic due to the spatial distribution and kinematics of sources in the Milky Way. In this work, we mode…
LISA science ground segment conventions
Quentin Baghi, Stanislas Babak, Leor Barack +22
This document sets out the conventions used for data simulations, waveforms, and analysis pipelines within the Distributed Data Processing Centre (DDPC) of the Laser Interferometer…
Statistics of time and frequency-averaged spectra in gravitational-wave background searches
Quentin Baghi, Nikolaos Karnesis, Jean-Baptiste Bayle
Time series analysis from gravitational-wave detectors often relies on the assumption that time chunks, or frequency bins, are uncorrelated. We discuss the validity of this approxi…
Effect of noise characterization on the detection of mHz stochastic gravitational waves
Nikolaos Karnesis, Quentin Baghi, Jean-Baptiste Bayle +1
Pulsar timing arrays' hint for a stochastic gravitational-wave background (SGWB) leverages the expectations of a future detection in the millihertz band, particularly with the LISA…
