Gravitational-wave (GW) dark siren methods offer a powerful way to measure the expansion of the Universe without electromagnetic counterparts, but they rely critically on accurate models of the underlying binary black-hole (BBH) population. In fact, conventional parametric descriptions of BBH mass and redshift distributions can lead to significant biases in cosmological inferences when the...

The upcoming ESA mission LISA (Laser Interferometer Space Antenna), scheduled for launch in 2037, will usher in a transformative era in astrophysics by detecting gravitational waves from space. Unlike traditional observatories limited to the electromagnetic spectrum, LISA will directly probe the fabric of space-time, revealing a new and complex landscape of astrophysical signals from galactic...

Current efforts in the LIGO-Virgo-KAGRA (LVK) collaboration focus on either parameter estimation from the observations of all available detectors, or denoising the measurements from a single detector. In this work, we address an intermediate task: reconstructing the original gravitational wave (GW) from the measurements of all available detectors. This inverse problem is ill-posed, and thus...
