Revisiting primordial magnetic fields through 21-cm physics: Bounds and forecasts
Arko Bhaumik, Debarun Paul, Supratik Pal
Primordial magnetic fields (PMFs) may significantly influence 21-cm physics via two mechanisms: (i) magnetic heating of the intergalactic medium (IGM) through ambipolar diffusion (…
Primordial Gravitational Waves as Probe of Dark Matter in Interferometer Missions: Fisher Forecast and MCMC
Anish Ghoshal, Debarun Paul, Supratik Pal
We propose novel inflationary primordial gravitational wave (GW) spectral shapes at interferometer-based current and future GW missions to test dark matter (DM) production via grav…
Post-inflationary Leptogenesis and Dark Matter production: Metric versus Palatini formalism
Anish Ghoshal, Zygmunt Lalak, Supratik Pal +1
We investigate production of non-thermal dark matter particles and heavy sterile neutrinos from inflaton during the reheating era, which is preceded by a slow-roll inflationary epo…
