Leptogenesis in Brane-modified cosmology: Signatures in primordial gravitational waves
Amit Dutta Banik, Arnab Paul
We investigate the implications of brane-inspired modifications of the evolutionary history of the early universe on the process of baryogenesis via leptogenesis. A modified cosmic…
Exploring the Co-SIMP dark matter model using the 21-cm signal from the dark ages
Debarun Paul, Sourav Pal, Deepthi Moorkanat +3
The redshifted 21-cm signal from the dark ages offers a powerful probe of cosmological models and the underlying dark matter (DM) microphysics. We investigate deviations from the s…
Confronting the dark matter capture rate with a continuous gravitational wave probe of local neutron stars
Pooja Bhattacharjee, Amit Dutta Banik
Continuous gravitational waves (CGWs) from various astrophysical sources are one of the many future probes of upcoming gravitational wave (GW) search missions. Neutron stars (NSs)…
Accommodating muon and leptogenesis in a scotogenic model
A. Alvarez, A. Banik, R. Cepedello +4
We present a detailed study of a scotogenic model accommodating dark matter, neutrino masses and the anomalous magnetic moment of the muon while being consistent with the existing…
