How Late can the Dark Matter form in our universe?
Abir Sarkar, Subinoy Das, Shiv K. Sethi
We put constraints on the epoch of dark matter formation for a class of non-WIMP (Weakly Interacting Massive Particle) dark matter candidates. These models allow a fraction of Cold…
Reionization constraints on primordial magnetic fields
Kanhaiya L. Pandey, T. Roy Choudhury, Shiv K. Sethi +1
We study the impact of the extra density fluctuations induced by primordial magnetic fields on the reionization history in the redshift range: . We perform a comprehens…
Study of Redshifted HI from the Epoch of Reionization with Drift scan
Sourabh Paul, Shiv K. Sethi, Ravi Subrahmanyan +37
The detection of the Epoch of Reionization (EoR) in the redshifted 21-cm line is a challenging task. Here we formulate the detection of the EoR signal using the drift scan strategy…
HI absorption from the epoch of reionization and primordial magnetic fields
Evgenii O. Vasiliev, Shiv K. Sethi
We study the impact of primordial magnetic fields on the HI absorption from the Epoch of Reionization. The presence of these fields result in two distinct effects: (a) the heating…
