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 combi…
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…
