Non-Gaussianity of Tensor Induced Density Perturbations
Mariam Abdelaziz, Pritha Bari, Sabino Matarrese +1
We investigate the non-Gaussianity of second-order matter density perturbations induced by primordial gravitational waves (GWs). These tensor-induced scalar modes arise from local…
Tracing Primordial Gravitational Waves via non-Gaussian Signatures of Halo Bias
Mariam Abdelaziz, Pritha Bari, Sabino Matarrese +1
Primordial gravitational waves (PGWs) generate scalar density perturbations at second order. Since the induced density contrast is quadratic in the tensor field, it is intrinsicall…
Gravitational waves induced by scalar-tensor mixing
Pritha Bari, Nicola Bartolo, Guillem Domènech +1
This paper explores the physics of second-order gravitational waves (GWs) induced by scalar-tensor perturbation interactions in the radiation-dominated Universe. We investigate the…
