Is the $Λ$ CDM Model in Crisis?

Himanshu Chaudhary, Salvatore Capozziello, Subhrat Praharaj +2

We present strong evidence for dynamical dark energy that challenges the standard $Λ$ CDM model. Several dark energy scenarios are explored, including $ω_{0} ω_{a}$ CDM, logarithmic, expo…

On the impact of $f (Q)$ gravity on the Large Scale Structure

Oleksii Sokoliuk, Simran Arora, Subhrat Praharaj +2

We investigate the exponential $f (Q)$ symmetric teleparallel gravitation, namely $f (Q) = Q + α Q_{0} (1 - e^{- β Q / Q_{0}})$ using \texttt{ME-GADGET} code to probe the structure formation…

Accretion flows around exotic tidal wormholes I. Ray-tracing

Oleksii Sokoliuk, Subhrat Praharaj, Alexander Baransky +1

This paper investigates the various spherically symmetric wormhole solutions in the presence of tidal forces and applies numerous methods, such as test particle orbital dynamics, r…
