Impact of Scale-dependent Primordial Non-Gaussianity on Scalar-induced Gravitational Waves
Alisha Marriott-Best, Devanshu Sharma, Anish Ghoshal +1
Scalar-induced gravitational waves (SIGWs) probe primordial curvature perturbations beyond cosmic microwave background scales, while primordial black holes (PBHs) probe the rare ta…
Inflationary Kicks and Coulomb Filtering of Spectator Dark Matter
Martina La Rosa, Rasheshwari Paul Chowdhury, Gianmassimo Tasinato
Light spectator fields provide a compelling inflationary origin for scalar dark matter, but their primordial fluctuations often generate excessive isocurvature perturbations on lar…
Relaxation without ringdown for a compact object in modified gravity
Gianmassimo Tasinato
Compact objects with black-hole-like exteriors may hide new strong-field physics in their interiors, making their dynamical response a sensitive probe of gravity beyond General Rel…
Probing Kinematic Anisotropies in the Stochastic Gravitational Wave Background with the SKA
N. M. J. Cruz, Ameek Malhotra, Gianmassimo Tasinato +1
Pulsar Timing Arrays (PTAs) and astrometric surveys provide complementary probes of the nanohertz stochastic gravitational-wave background (SGWB). A primary target is the kinematic…
Data-Driven Discovery of a Simple Phantom-Crossing Dark Energy Parametrization
Giulia Borghetto, Ameek Malhotra, Simran Arora +4
We develop a data-driven reconstruction programme for the dark-energy equation of state within VCDM, a minimally modified gravity framework in which both background and linear pert…
Wave-optics gravitational wave lensing in modified gravity
Alice Garoffolo, Gianmassimo Tasinato
We initiate the study of gravitational-wave lensing in the wave-optics regime within modified gravity. We consider a phenomenological setup in which the gravitational-wave amplitud…
