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…

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…
