Gravitational Waves- a new window to Cosmos
A. R. Prasanna
With the detection of Gravitational waves just about an year ago Einstein`s general theory of relativity- a space-time theory of gravity, got established on a firmer footing than a…
Constraints on cosmological viscosity and self interacting dark matter from gravitational wave observations
Gaurav Goswami, Girish Kumar Chakravarty, Subhendra Mohanty +1
It has been shown that gravitational waves propagate through ideal fluids without experiencing any dispersion or dissipation. However, if the medium has a non-zero shear viscosity…
Neutrino coupling to cosmological background: A review on gravitational Baryo/Leptogenesis
G. Lambiase, S. Mohanty, A. R. Prasanna
In this work we review the theories of origin of matter-antimatter asymmetry in the Universe. The general conditions for achieving baryogenesis and leptogenesis in a CPT conserving…
Constraints on background torsion from birefringence of CMB polarization
Moumita Das, Subhendra Mohanty, A. R. Prasanna
We show that a non-minimal coupling of electromagnetism with background torsion can produce birefringence of the electromagnetic waves. This birefringence gives rise to a B-mode po…
Leptogenesis from Spin-Gravity Coupling Following Inflation
Subhendra Mohanty, A. R. Prasanna, G. Lambiase
The energy levels of the left and the right handed neutrinos is split in the background of gravitational waves generated during inflation which in presence of lepton number violati…
Gauge Invariant Wave Equations in Curved Space-Times and Primordial Magnetic Fields
G. Lambiase, A. R. Prasanna
The inflationary production of magnetic field seeds for galaxies is discussed. The analysis is carried out by writing the wave equation of the electromagnetic field in curved space…
