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…
Primordial Gravitational Waves as Complementary Probe of Dark Matter Indirect Detection
Anish Ghoshal, Debarun Paul, Supratik Pal
We propose a novel cosmological probe of dark matter (DM) through inflationary primordial gravitational wave (GW) measurements highlighting its complementarity with traditional ind…
Improved Predictions on Higgs-Starobinsky Inflation and Reheating with ACT DR6 and Primordial Gravitational Waves
Md Riajul Haque, Sourav Pal, Debarun Paul
We investigate the implications of recent CMB observations for Higgs-Starobinsky inflationary models and their associated reheating dynamics, utilizing data from ACT DR6, Planck 20…
Axion Dark Matter Archaeology with Primordial Gravitational Waves
Andrew Cheek, Anish Ghoshal, Debarun Paul
We investigate the complementary information to be gained from inflationary gravitational wave (IGW) signals and searches for QCD axion dark matter. We focus on post-inflationary P…
ACT DR6 Insights on the Inflationary Attractor models and Reheating
Md Riajul Haque, Sourav Pal, Debarun Paul
We investigate the observational constraints on -attractor inflationary models and their post-inflationary reheating dynamics in light of the latest CMB data from ACT DR6 combin…
Gravitational Wave Signatures of Primordial Black Hole Reheating in Upcoming Interferometry Missions
Debarun Paul, Md Riajul Haque, Supratik Pal
We investigate the prospects of detecting a stochastic gravitational wave (GW) background from the primordial black hole (PBH) reheating epoch. If PBHs form during a non-standard c…
