Accelerating LISA inference with Gaussian processes
Jonas El Gammal, Riccardo Buscicchio, Germano Nardini +1
Source inference for deterministic gravitational waves is a computationally demanding task in LISA. In a novel approach, we investigate the capability of Gaussian Processes to lear…
Complementary Probes of Warped Extra Dimension: Colliders, Gravitational Waves and Primordial Black Holes from Phase Transitions
Anish Ghoshal, Eugenio Megias, Germano Nardini +1
We study the formation of primordial black holes (PBHs) and stochastic gravitational waves background (SGWB) produced by the supercooled radion phase transition (PT) in warped extr…
Reconstructing Primordial Curvature Perturbations via Scalar-Induced Gravitational Waves with LISA
Jonas El Gammal, Aya Ghaleb, Gabriele Franciolini +17
Many early universe scenarios predict an enhancement of scalar perturbations at scales currently unconstrained by cosmological probes. These perturbations source gravitational wave…
Gravitational waves from cosmic strings in LISA: reconstruction pipeline and physics interpretation
Jose J. Blanco-Pillado, Yanou Cui, Sachiko Kuroyanagi +6
We initiate the LISA template databank for stochastic gravitational wave backgrounds sourced by cosmic strings. We include two templates, an analytical template, which enables more…
Gravitational waves from inflation in LISA: reconstruction pipeline and physics interpretation
Matteo Braglia, Gianluca Calcagni, Gabriele Franciolini +8
Various scenarios of cosmic inflation enhance the amplitude of the stochastic gravitational wave background (SGWB) at frequencies detectable by the LISA detector. We develop tools…
