Thurston geometries and parameter constraints from SNIa data
Tanay Gupta, Anshul Verma, Sukanta Panda +1
Following the numerous evidence for large-scale cosmic isotropy violation with the advent of the `precision cosmology' era, we explore the possible advantages of extending the flat…
Phantom Menace in general Palatini theories
Rahul Thakur, Abhijith Ajith, Sukanta Panda +1
We study general theories in Palatini formalism and attempt to constrain the behavior of ones that could support both inflationary and late-time expansion era in a unified…
Eff-ACT-ive Starobinsky pre-inflation
Abhijith Ajith, Hardik Jitendra Kuralkar, Sukanta Panda +1
We consider quantum corrections to a recently obtained perturbative form of Starobinsky model to extract information about the initial conditions of the universe leading to cosmolo…
Observable Primordial Gravitational Waves from Non-minimally Coupled Palatini Modified Gravity
Hardik Jitendra Kuralkar, Sukanta Panda, Archit Vidyarthi
We probe the spectrum of primordial gravitational waves (GWs) produced during the eras of hyperkination, kination, and reheating in a non-minimally coupled, $\mathcal{L} \propto (1…
