Tracing Signatures of Modified Gravity in Redshift-Space Galaxy Bispectrum Multipoles: Prospects for Euclid
Sourav Pal, Debanjan Sarkar, Alejandro Aviles
We study the galaxy bispectrum multipoles in the Hu-Sawicki gravity model, where a scalar degree of freedom mediates a fifth force that is screened in high-density environme…

Redshift-space galaxy bispectrum in presence of massive neutrinos: A multipole expansion approach for Euclid
Sourav Pal, Debanjan Sarkar, Rickmoy Samanta +1
Massive neutrinos imprint distinctive signatures on the evolution of cosmic structures, notably suppressing small-scale clustering. We investigate the impact of massive neutrinos o…
