Primordial magnetic fields and formation of molecular hydrogen
Shiv K Sethi, Biman B. Nath, Kandaswamy Subramanian
We study the implications of primordial magnetic fields for the thermal and ionization history of the post-recombination era. In particular we compute the effects of dissipation of…
Dust sputtering by Reverse Shocks in Supernova Remnants
Biman B. nath, Tanmoy Laskar, J. Michael Shull
We consider sputtering of dust grains, believed to be formed in cooling supernovae ejecta, under the influence of reverse shocks. In the regime of self-similar evolution of reverse…
Dynamical friction of radio galaxies in galaxy clusters
Biman B. Nath
The distribution of luminous radio galaxies in galaxy clusters has been observed to be concentrated in the inner region. We consider the role of dynamical friction of massive galax…
Limits on the AGN activities in X-ray underluminous galaxy groups
K. S. Dwarakanath, Biman B. Nath
We have observed four X-ray underluminous groups of galaxies using the Giant Meterwave RadioTelescope. The groups NGC 524, 720, 3607, and 4697 are underluminous in relation to the…
Cosmic rays, lithium abundance and excess entropy in galaxy clusters
Biman B. Nath, Piero Madau, Joseph Silk
We consider the production of Li in spallation reactions by cosmic rays in order to explain the observed abundance in halo metal-poor stars. We show that heating of ambient gas…
The Radiative Transport of Dust in Primordial Galaxies and Second-Generation Star Formation
Aparna Venkatesan, Biman B. Nath, J. Michael Shull
We investigate the radiative transport of dust in primordial galaxies in the presence of the UV radiation field from the first metal-free stars. We find that dust created in the fi…
