No preference for generalized emergent dark energy from current cosmological data
Vipin Kumar Sharma, Himanshu Chaudhary, Salvatore Capozziello +2
In this work, we revisit the generalized emergent dark energy model by confronting it with DESI DR2 baryon acoustic oscillation measurements, in combination with joint CMB data fro…
Inflation Driven by Scalar-Neutrino Coupling in a Mass-Varying Neutrino Framework
Hemanshi Bundeliya, Gaurav Bhandari, S. D. Pathak +1
We propose a cosmological framework in which neutrino masses evolve dynamically through coupling with a scalar field that simultaneously drives inflation. The neutrino mass is mode…
Probing departures from CDM by late-time datasets
Himanshu Chaudhary, Vipin Kumar Sharma, Salvatore Capozziello +1
Observational data play a pivotal role in identifying cosmological models that are both theoretically consistent and empirically viable. In this work, we investigate the level of p…
Evidence for evolving dark energy from DESI DR2 BAO and Pantheon, DES-Dovekie, and Union3
Himanshu Chaudhary, Salvatore Capozziello, Vipin Kumar Sharma +2
Evidences for evolving dark energy are shown using baryon acoustic oscillation measurements from the recent Dark Energy Spectroscopic Instrument Data Release 2 , combined with diff…
Does DESI DR2 challenge CDM paradigm ?
Himanshu Chaudhary, Salvatore Capozziello, Vipin Kumar Sharma +1
Although debate on DESI DR1 systematics remains, DESI DR2 is consistent with DR1 and strengthens its trends. In our analysis, the LRG1 point at and the LRG…
Probing Generalized Emergent Dark Energy with DESI DR2
Vipin kumar Sharma, Himanshu Chaudhary, Sanved Kolekar
As an update on the initial findings of DESI, the new results provide the first hint of potential deviations from a cosmological constant (), which, if confirmed with signifi…
