Probing Interacting Dark Sectors with upcoming Post-Reionization and Galaxy Surveys
Rahul Shah, Antara Dey, Purba Mukherjee +1
We investigate the constraining power of future post-reionization and galaxy surveys on possible interactions between dynamical dark energy and dark matter. The analysis focuses on…
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…
What can we learn about Reionization astrophysical parameters using Gaussian Process Regression?
Purba Mukherjee, Antara Dey, Supratik Pal
Reionization is one of the least understood processes in the evolution history of the Universe, mostly because of the numerous astrophysical processes occurring simultaneously abou…
Confronting global 21-cm signal with symmetric dark matter models
Debarun Paul, Antara Dey, Amit Dutta Banik +1
While the symmetric dark matter models have shown tremendous prospects in addressing a number of (astro-)particle physics problems, they can leave interesting imprin…
Imprints of dark matter-massive neutrino interaction in upcoming post-reionization and galaxy surveys
Antara Dey, Arnab Paul, Supratik Pal
We explore possible signatures of the interaction between dark matter (DM) and massive neutrinos during the post-reionization epoch. Using both Fisher matrix forecast analysis and…
Constraints on Dark Matter-Neutrino Interaction from 21-cm Cosmology and Forecasts on SKA1-Low
Antara Dey, Arnab Paul, Supratik Pal
In this article, we have done a thorough investigation of the possible effects of interaction between dark matter (DM) and neutrinos on reionization history. We have constrained th…
