Testing Exponential Gravity with CMB, DESI-DR2, and Supernova Data
Saurabh Verma, Archana Dixit, Anirudh Pradhan +1
One of the most popular competitors to the CDM paradigm as an explanation for the late-time acceleration of the universe is the modification of general relativity (GR), with models…
Extended thermodynamics and Criticality of Kalb-Ramond black hole coupled with nonlinear electrodynamics
D. V. Singh, S. Upadhyay, P. Paul +1
We present an exact black hole solution in anti-de Sitter (AdS) spacetime with a Kalb-Ramond field coupled to nonlinear electrodynamics (NLED), characterized by mass, magnetic mono…
Comparative Study of Gravity Models with Observational Constraints from \textit{OHD} and \textit{Pantheon+ datasets}
Anirudh Pradhan, S. A. Salve, V. B. Raut +1
The late-time acceleration of the universe remains one of the most significant open problems in modern cosmology. Modified gravity frameworks such as gravity provide a geome…
Generalized Second Law and Thermodynamical Aspects of Gravity
Anirudh Pradhan, A. Husain, M. Zeyauddin +1
Late-time cosmic acceleration has motivated the exploration of various extensions of general relativity, among which gravity, based on the non-metricity scalar $…
Thermodynamics, Shadow, and Quasinormal Modes of AdS Ayón--Beato--GarcÃa Massive Black Hole
Dharm Veer Singh, Sudhaker Upadhyay, Amit Kumar +3
We investigate the thermodynamics, photon sphere, and dynamical stability of an AdS Ayón--Beato--GarcÃa (ABG) massive black hole with graviton mass and magnetic charge. The Gibbs…
Dynamical Dark Energy Signatures from a New Transition Parametrization in Flat FLRW Cosmology
Manish Yadav, Archana Dixit, Anirudh Pradhan +1
We investigate a cosmic scenario using a new transition parameterization of the diagnostic, , in the spatially flat Friedmann Lemaître Roberts…
