Comparing Mass-Varying Neutrino Dark Energy Models with DESI DR2: Cosmological Constraints and Bayesian Evidence
Hemanshi Bundeliya, Gaurav Bhandari, Mohammad Yarahmadi +3
We investigate late-time cosmic acceleration in mass-varying neutrino (MaVaN) dark energy scenarios, where the neutrino mass is coupled to a dynamical quintessence field through a…

Exploring the Observational Constraints and Cosmological Dynamics in f(Q,L_m) Gravity
Ratul Mandal, Anamika Kotal, Vipin Kumar Sharma +1
We explore two scenarios of gravity: linear and non-linear gravity models. The dynamical system analysis identifies two critical points for each of the propose…
