Effect of General Relativity and rotation on the energy deposition rate for $ν + ν ˉ \to e^{+} + e^{-}$ inside a compact star

Abhijit Bhattacharyya, Sanjay K. Ghosh, Ritam Mallick +1

We have studied the $ν + ν ˉ \to e^{+} + e^{-}$ energy deposition rate in a rotating compact star. This reaction is important for the study of gamma ray bursts. The General Relativis…

The Cosmic QCD Phase Transition, Quasi-baryonic Dark Matter and Massive Compact Halo Objects

Shibaji Banerjee, Abhijit Bhattacharyya, Sanjay K. Ghosh +3

We propose that the cold dark matter (CDM) is composed entirely of quark matter, arising from a cosmic quark-hadron transition. We denote this phase as "quasibaryonic", distinct fr…

The Cosmological Quark-Hadron Transition and Massive Compact Halo Objects

Shibaji Banerjee, Abhijit Bhattacharyya, Sanjay K. Ghosh +2

One of the abiding mysteries in the so-called standard cosmological model is the nature of the dark matter. It is universally accepted that there is an abundance of matter in the u…
