Strange Star Equation of State With a Modified Richardson Potential
Manjari Bagchi, Subharthi Ray, Mira Dey +1
Richardson potential is an phenomenological interquark interaction taking care of two aspects of QCD, namely the asymptotic freedom and the confinement. The original potential has…
High and ultra-high energy cosmic ray acceleration in structure-formation shocks in Abell 3376 galaxy cluster
J. Bagchi, Florence Durret, Gastao B. Lima Neto +2
We describe multiwavelength optical, X-ray and radio evidences of energetic mergers in southern galaxy cluster Abell 3376 (A3376, redshift z=0.046, X-ray luminosity $ \rm L_{X}(0.1…
Cosmic ray electron acceleration in the remnant of nova GK Persei?
N. G. Kantharia, G. C. Anupama, Prasad Subramanian
Radio observations of the nova remnant of GK Per around 1985 (epoch 1) have shown it to have a spectral index of -0.4 (S propto nu^alpha) at frequencies <1.4 GHz and a spectral ind…
Using transport coefficients of cosmic rays in turbulent magnetic fields to determine hybrid viscosity in hot accretion disks around AGN
Prasad Subramanian, Peter A. Becker, Menas Kafatos
The nature of the viscosity operative in hot, two-temperature accretion disks around AGN has been a long-standing, unsolved problem. It has been previously suggested that protons,…
Strong mean field dynamos require supercritical helicity fluxes
Axel Brandenburg, Kandaswamy Subramanian
Several one and two dimensional mean field models are analyzed where the effects of current helicity fluxes and boundaries are included within the framework of the dynamical quench…
Minimal tau approximation and simulations of the alpha effect
A. Brandenburg, K. Subramanian
The validity of a closure called the minimal tau approximation (MTA), is tested in the context of dynamo theory, wherein triple correlations are assumed to provide relaxation of th…
