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…
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…
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…
An Analytical Study of the Primordial Gravitational-Wave-Induced Contribution to the Large-Scale Structure of the Universe
Pritha Bari, Daniele Bertacca, Nicola Bartolo +3
The imprint of gravitational waves (GWs) on large-scale structures (LSS) is a useful and promising way to detect or to constrain them. Tensor fossils have been largely studied in t…
Signatures of Primordial Gravitational Waves on the Large-Scale Structure of the Universe
Pritha Bari, Angelo Ricciardone, Nicola Bartolo +2
We study the generation and evolution of second-order energy-density perturbations arising from primordial gravitational waves. Such "tensor-induced scalar modes" approximately evo…
