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…
Exploring Coupled Quintessence in light of CMB and DESI DR2 measurements
Atul Ashutosh Samanta, Abhijith Ajith, Sukanta Panda
We perform a detailed analysis of a theoretically motivated dark energy quintessence model which interacts with the dark matter sector of the universe. Utilising the current observ…
Scalar and vector modes in inflation with antisymmetric tensor field
Abhijith Ajith, Sukanta Panda
We investigate the scalar and vector modes arising from cosmological perturbations within the framework of an inflationary scenario driven by an antisymmetric tensor field, minimal…
Evidence for non-cold dark matter from DESI DR2 measurements
Utkarsh Kumar, Abhijith Ajith, Amresh Verma
We investigate potential deviations from cold dark matter (CDM) using the latest Baryon Acoustic Oscillations (BAO) measurements from the Dark Energy Spectroscopic Instrument (DESI…
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…
