Cosmological consequences of a dynamical dark matter in the light of DESI DR2 measurements
Abhijith Ajith, Utkarsh Kumar
Recent DESI results exhibit preference for a Null Energy Condition violating dynamical dark energy, with early phantom behaviour. We explore an alternative interpretation in which…
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…
Inflation using a triplet of Antisymmetric tensor fields
Abhijith Ajith, Sukanta Panda
We study an inflation model driven by a triplet of antisymmetric tensor fields, with minimal and nonminimal couplings to gravity. First, we show that the presence of a triplet of a…
Inflation with antisymmetric tensor field: new candidates
Sandeep Aashish, Abhijith Ajith, Sukanta Panda +1
We study classes of inflation models driven by antisymmetric tensor field, with minimal and nonminimal couplings to gravity, that address known issues of such models considered in…
