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…

Primordial magnetic fields in the light of upcoming post-EoR Lyman- and 21-cm observations
Arko Bhaumik, Sourav Pal, Supratik Pal
The Lorentz force exerted by a primordial magnetic field (PMF) on the coupled baryon-dark matter system may enhance total matter power at small scales after recombination. In the p…

Neutrino self-interactions in post-reionization era: Lyman-, 21-cm and cross-spectra
Sourav Pal, Supratik Pal
Neutrino self-interactions delay the onset of free-streaming in the early universe, leaving distinct, scale-dependent signatures on the matter power spectrum. We investigate these…
