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…
Revisiting coupled CDM-massive neutrino perturbations in diverse cosmological backgrounds
Sourav Pal, Rickmoy Samanta, Supratik Pal
Massive neutrinos are well-known to cause a characteristic suppression in the growth of structures at scales below the neutrino free-streaming length. A detailed understanding of t…
Role of Future SNIa Data from Rubin LSST in Reinvestigating Cosmological Models
Rahul Shah, Ayan Mitra, Purba Mukherjee +2
We study how future Type-Ia supernovae (SNIa) standard candles detected by the Vera C. Rubin Observatory (LSST) can constrain some cosmological models. We use a realistic three-yea…
Reconstructing the Hubble parameter with future Gravitational Wave missions using Machine Learning
Purba Mukherjee, Rahul Shah, Arko Bhaumik +1
We study the prospects of Gaussian processes (GP), a machine learning (ML) algorithm, as a tool to reconstruct the Hubble parameter with two upcoming gravitational wave miss…
A thorough investigation of the prospects of eLISA in addressing the Hubble tension: Fisher Forecast, MCMC and Machine Learning
Rahul Shah, Arko Bhaumik, Purba Mukherjee +1
We carry out an in-depth analysis of the capability of the upcoming space-based gravitational wave mission eLISA in addressing the Hubble tension, with a primary focus on observati…
