Multiband optical flux density and polarization microvariability study of optically bright blazars
Magdalena Pasierb, Arti Goyal, Michał Ostrowski +21
We present the results of flux density, spectral index, and polarization intra-night monitoring studies of a sample of eight optically bright blazars, carried out by employing seve…
Generation of CMB and Cosmological constant via bulk viscosity
Sanved Kolekar, S. Shankaranarayanan, S. M. Chitre
A simple model of uniformly expanding, homogeneous Universe with a bulk viscosity is studied wherein the inflationary density decays due to viscous dissipation during the expansion…
Directional dependence of the Unruh effect for spatially extended detectors
Sanved Kolekar
We analyse the response of a spatially extended direction-dependent local quantum system, a detector, moving on the Rindler trajectory of uniform linear acceleration in Minkowski s…
X-shaped Radio Galaxies: Optical Properties, Large-scale Environment and Relationship to Radio Structure
Ravi Joshi, Gopal-Krishna, Xiaolong Yang +9
In order to find clues to the origin of the "winged" or "X-shaped" radio galaxies (XRGs) we investigate here the parent galaxies of a large sample of 106 XRGs for optical-radio axe…
Proposal for a new quantum theory of gravity III: Equations for quantum gravity, and the origin of spontaneous localisation
Palemkota Maithresh, Tejinder P. Singh
We present a new, falsifiable, quantum theory of gravity, which we name Non-commutative Matter-Gravity. The commutative limit of the theory is classical general relativity. In the…
Intrinsic Cluster-Shaped Density Waves in Cellular Dynamical Mean-Field Theory
S. Verret, J. Roy, A. Foley +3
It is well known that cellular dynamical mean-field theory (CDMFT) leads to the artificial breaking of translation invariance. In spite of this, it is one of the most successful me…
