Can spacetime torsion source an extremely red-tilted cosmological GW background?

Arko Bhaumik, Bhaswati Mandal, Soumitra SenGupta

In the presence of spacetime torsion, any generic $f (R)$ model of gravity is conformally dual to a scalar-tensor theory augmented with a second rank antisymmetric massless degree o…

Vector induced Gravitational Waves sourced by Primordial Magnetic Fields

Arko Bhaumik, Theodoros Papanikolaou, Anish Ghoshal

In this work, we develop a generic formalism for the study of tensor perturbations induced at second order by first-order vector metric perturbations, dubbing these induced tensor…
