Probing Cosmology beyond ΛCDM using the SKA
Ghosh, Shamik; Jain, Pankaj; Kothari, Rahul (Indian Academy of Sciences, 2023)The cosmological principle states that the Universe is statistically homogeneous and isotropic at large distance scales. Currently, there exist many observations which indicate a departure from this principle. It has ... -
Superhorizon perturbations: A possible explanation of the hubble–lemaître tension and the large-scale anisotropy of the universe
Tiwari, Prabhakar; Kothari, Rahul; Jain, Pankaj (IOP Publishing, 2022)Current cosmological observations point to a serious discrepancy between the observed Hubble parameter obtained using direct versus cosmic microwave background radiation measurements. Besides this so-called Hubble– Lemaî tre ... -

Torsion driven inflationary magnetogenesis
Kothari, Rahul; Saketh, M. V. S.; Jain, Pankaj (American Physical Society, 2020)We show that the breaking of the conformal invariance of the electromagnetic Lagrangian, which is required for inflationary magnetogenesis, arises naturally in the Poincaré gauge theory. We use the minimal coupling ...
