New cosmological constraints on f(T) gravity in light of full Planck-CMB and type Ia supernovae data

Kumar, Suresh; Nunes, Rafael da Costa; Yadav, Priya (2023) [Artículo de periódico]

We investigate two new observational perspectives in the context of torsional gravitational modification of general relativity, i.e., the f(T) gravity: (i) We use Pantheon data of type Ia supernovae motivated by a time ...
New tests of dark sector interactions from the full-shape galaxy power spectrum

Nunes, Rafael da Costa; Vagnozzi, Sunny; Kumar, Suresh; Di Valentino, Eleonora; Mena Requejo, Olga (2022) [Artículo de periódico]

We explore the role of redshift-space galaxy clustering data in constraining nongravitational interactions between dark energy (DE) and dark matter (DM), for which state-of-the-art limits have so far been obtained from ...
