Bounds on Neutrino Mass in Viscous Cosmology
Sampurn Anand, Prakrut Chaubal, Arindam Mazumdar +2
Effective field theory of dark matter fluid on large scales predicts the presence of viscosity of the order of . It has been shown that this magnitude of viscosi…
Revisiting CMB constraints on Warm Inflation
Richa Arya, Arnab Dasgupta, Gaurav Goswami +2
We revisit the constraints that Planck 2015 temperature, polarization and lensing data impose on the parameters of warm inflation. To this end, we study warm inflation driven by a…
Viscous Self Interacting Dark Matter and Cosmic Acceleration
Abhishek Atreya, Jitesh R. Bhatt, Arvind Mishra
Self interacting dark matter (SIDM) provides us with a consistent solution to certain astrophysical observations in conflict with collision-less cold DM paradigm. In this work we e…
Cosmic viscosity as a remedy for tension between PLANCK and LSS data
Sampurn Anand, Prakrut Chaubal, Arindam Mazumdar +1
Measurements of from large scale structure observations show a discordance with the extrapolated from Planck CMB parameters using CDM cosmology. Similar discordance…
Chiral Battery, scaling laws and magnetic fields
Sampurn Anand, Jitesh R. Bhatt, Arun Kumar Pandey
We study the generation and evolution of magnetic field in the presence of chiral imbalance and gravitational anomaly which gives an additional contribution to the vortical current…
