Constraining inflationary models via de-Sitterization of Bianchi Cosmologies
Apurba Samanta, Rahul Kothari
Our Universe is isotropic and homogeneous when we observe it on Mpc length scales. It is desirable that present state of the Universe has no dependence on its initial geo…
Constraining Lorentz Violation using 21cm and CMB Cross Correlations
Bhuwan Joshi, Rahul Kothari, Shyam Chaudhary
Lorentz symmetry is a fundamental pillar of modern Physics, yet high-energy theories often predict its violation. One potential signature of such a violation is cosmic birefringenc…
Constraining Statistical Isotropy using 21cm Power Spectrum and Bispectrum
Bhuwan Joshi, Rahul Kothari
The Cosmological Principle states that the universe is statistically isotropic and homogeneous on large length scales, typically Mpc. A detection of significant deviati…
A wide-angle formulation of foreground filters for HI intensity mapping
Rahul Kothari, Roy Maartens
Neutral hydrogen intensity mapping can in principle deliver rapid and large-volume cosmological surveys with exquisitely accurate redshifts that are determined directly from imagin…
Probing Cosmology beyond CDM using the SKA
Shamik Ghosh, Pankaj Jain, Rahul Kothari +3
The cosmological principle states that the Universe is statistically homogeneous and isotropic at large distance scales. There currently exist many observations which indicate a de…
A study of Dipolar Signal in distant Quasars with various observables
Rahul Kothari, Mohit Panwar, Gurmeet Singh +2
We study the signal of anisotropy in AGNs/quasars of CatWISE2020 catalogue using different observables. It has been reported earlier that this data shows a strong signal of dipole…
