Unimodular Diffusion and Interacting Vacuum Cosmology
Gopal Kashyap, Naveen K. Singh
We investigate the correspondence between unimodular diffusion cosmology and interacting dark sector models at the background and linear perturbation levels. In the diffusion frame…
Unimodular Theory of Gravity in Light of the Latest Cosmological Data
Naveen K. Singh, Gopal Kashyap
The unimodular theory of gravity is an alternative perspective to traditional Einstein's general relativity and opens new possibilities for exploring its implications in cosmology.…
Dipole Anisotropy in Gravitational Wave Source Distribution
Gopal Kashyap, Naveen K. Singh, Khun Sang Phukon +2
Our local motion with respect to the cosmic frame of rest is believed to be dominantly responsible for the observed dipole anisotropy in the Cosmic Microwave Background Radiation (…
Can Non-standard Recombination Resolve the Hubble Tension?
Miaoxin Liu, Zhiqi Huang, Xiaolin Luo +3
The inconsistent Hubble constant values derived from cosmic microwave background (CMB) observations and from local distance-ladder measurements may suggest new physics beyond the s…
Weak Lensing Effect on CMB in the Presence of a Dipole Anisotropy
Abhineet Agarwal, Naveen K. Singh, Pankaj Jain +1
We investigate weak lensing effect on cosmic microwave background (CMB) in the presence of dipole anisotropy. The approach of flat-sky approximation is considered. We determine the…
Anti-Evaporation/Evaporation of -dimensional Reissner-Nordström Black Hole
YuHong Fang, Zhiqi Huang, HaiTao Miao +1
We generalize -theory of anti-evaporation/evaporation for a Reissner-Nordström black hole in -dimensional space-time. We consider non-linear conformally invariant Maxwell…
