Suppression of the induced gravitational wave background due to third-order perturbations
Raphael Picard, Luis E. Padilla, Karim A. Malik +1
In this work, we revisit and evaluate new source terms which contribute to the induced gravitational wave background. We study their respective contributions to the stochastic grav…

Induced gravitational waves: the effect of first order tensor perturbations
Raphael Picard, Karim A. Malik
Scalar induced gravitational waves contribute to the cosmological gravitational wave background. They can be related to the primordial density power spectrum produced towards the e…
