Modifications of CMB Temperature and Polarization Quadrupole Signals in Thurston Spacetimes
Tanay Gupta, Sukanta Panda, Rajib Saha
Recent cosmological tests have discovered a fresh new set of anomalies in the large-scale isotropy of the universe. Motivated thus by the numerous pieces of evidence for large-scal…
Oscillon Formation in Palatini Modified Gravity Theories
Shreyas Upadhye, Sukanta Panda
We investigate the formation of spatially localized, oscillatory in time and non topological solitonic, quasi-stable energy configurations, Oscillons, which are formed at the end o…
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…
Cosmological viability of anisotropic inflation in Thurston spacetimes
Devika J. S., Tanay Gupta, Sukanta Panda
Recent observations of large-scale statistical isotropy violations have prompted the adoption of anisotropic cosmological models that account for inherent directional curvature. St…
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…
Testing the Starobinsky model of inflation with resonant cavities
Subhendra Mohanty, Sukanta Panda, Archit Vidyarthi
We show that the Starobinsky inflation model based on gravity has a special feature that it provides a unique scalaron-two-graviton vertex with a coupling proportional to $1/…
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…
Quantizable Ghost-ridden theories using Kinetic Positivity Constraints
Sukanta Panda, Archit Vidyarthi
We present a novel way to constrain the ghost field with respect to other physical fields present in a given theory such that the theory becomes quantizable. This is achieved by im…
Role of Spatial Curvature in a Dark Energy Interacting Model
Trupti Patil, Sukanta Panda
This paper investigates the effects of spatial curvature in a model where dark matter and dark energy interact. The analysis employs a range of datasets, including CMB, BAO, Type I…
