Tracing Ultra Light Axions in Post-reionization, Lyman- and CMB Missions
Debarun Paul, Sourav Pal, Amit Dutta Banik +1
Ultra-light axions (ULAs) are dark matter candidates proposed to resolve the small scale anomalies of the standard cosmological model. Due to their inherent quantum pressure, ULAs…
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…
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…
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…
