Neutron Stars in Energy--Momentum Squared Gravity: Structure, Stability, and Multimessenger Constraints
Baiju Dayanandan, Anirudh Pradhan, Safiqul Islam +1
We study nonrotating neutron stars in energy--momentum squared gravity (EMSG). The stellar models are obtained from the modified Tolman--Oppenheimer--Volkoff equations and four ori…

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…
