We report results of a search for an isotropic gravitational-wave background (GWB) using
data from Advanced LIGO's and Advanced Virgo's third observing run (O3) combined with …

This paper presents the results of a search for generic short-duration gravitational-wave
transients in data from the third observing run of Advanced LIGO and Advanced Virgo …

Correlated magnetic noise in the form of Schumann resonances could introduce limitations
to the gravitational-wave background searches of future Earth-based gravitational-wave …

We present a new method which accounts for changes in the properties of gravitational-
wave detector noise over time in the PyCBC search for gravitational waves from compact …

While general relativity (GR) has certainly proven a formidable framework via which we
understand the past history and current dynamics of our Universe, modern observations are …

We present a cosmological model of an early-time scenario that incorporates a relaxation
process of the would-be large vacuum energy, followed by a reheating era connecting to the …

While general relativity (GR) has certainly proven a formidable framework via which we
understand the past history and current dynamics of our Universe, modern observations are …

Cette thèse porte sur la gravitation et certains de ses liens avec la théorie des champs. Le
point de départ de cette recherche a été l'étude de la limite newtonienne de la relativité …
