Gamma-Ray Bursts and Magnetars as Possible Sources of Ultra High Energy Cosmic Rays: Correlation of Cosmic Ray Event Positions with IRAS Galaxies
Shwetabh Singh, Chung-Pei Ma, Jonathan Arons
We use the two-dimensional Kolmogorov-Smirnov (KS) test to study the correlation between the 60 cosmic ray events above 4x10^19 eV from the AGASA experiment and the positions of in…
Neutrino Clustering in Cold Dark Matter Halos : Implications for Ultra High Energy Cosmic Rays
Shwetabh Singh, Chung-Pei Ma
We develop a method based on the collisionless Boltzmann equation to calculate the gravitational clustering of relic neutrinos in realistic cosmological models dominated by cold da…
Linear and Second-Order Evolution of Cosmic Baryon Perturbations below 10^6 Solar Masses
Shwetabh Singh, Chung-Pei Ma
Studies of the growth of cosmic perturbations are typically focused on galactic scales and above. In this paper we investigate the evolution of perturbations in baryons, photons, a…
Cosmological Models with Shear and Rotation
Shwetabh Singh
Cosmological models involving shear and rotation are considered, first in the General Relat ivistic and then in the Newtonian framework with the aim of investigating singularities…
