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…
Transient Parity Violation during Inflation: Implications for PTA Gravitational Waves
Gianmassimo Tasinato
We investigate the consequences of a transient phase of enhanced parity violation during inflation. Modeling this phase through a time-localized Chern--Simons-like coupling, we sho…
Chiral gravitational waves from multi-phase magnetogenesis
H. V. Ragavendra, Gianmassimo Tasinato, L. Sriramkumar
Cosmological vector fields are central to many early-Universe phenomena, including inflationary dynamics, primordial magnetogenesis, and dark-matter scenarios. However, constructin…
