Testing Gravity with DESI DR2 and Strong-Lensing Time Delays
Darshan Kumar, Saibal Ray, Fengge Zhang +3
Symmetric teleparallel gravity provides an alternative description of gravitation in which non-metricity replaces curvature and torsion. Its extension through gravity offers…
Probing Nonlinear Logarithmic Kalb-Ramond Black Holes: Particle Dynamics, Epicyclic Oscillations and Thermodynamic Signatures
Aftab Ansari, Rajesh Kumar, Praveen Kumar Dhankar
In contrast to conventional linear coupling frameworks, the proposed work investigated the nonlinear effects that become more significant in the strong field regime of a black hole…
Observational Constraints on Gravity in the Presence of DBI-Essence Scalar Field
Mayur Mune, Praveen Kumar Dhankar, Goutam Manna +3
We investigate late-time cosmology in extended symmetric teleparallel gravity coupled to a Dirac-Born-Infeld (DBI) scalar field within gravity, where is the non-metric…
Cosmic Hysteresis in Reconstructed Bounce Models A Torsion-Based Thermodynamic Perspective
Aritra Sanyal, Praveen Kumar Dhankar, Albert Munyeshyaka +3
We investigate the emergence of cosmic hysteresis in cyclic and bouncing cosmologies within the framework of reconstructed gravity. In contrast to curvature-based modificati…
A Bayesian Statistical Study of Bianchi Type-I Universe in Modified Gravity
Mohit Thakre, Praveen Kumar Dhankar, Safiqul Islam +3
We have examined the cosmological actions of LRS (Locally Rationally Symmetric) Bianchi type-I universe model in gravity. For this, we have estimated the Hubble paramete…
