Effective CDM model emerging from under a special EOS limit in symmetric cosmology with Bayesian and ANN observational constraints
Anil Kumar Yadav, S. H. Shekh, N. Myrzakulov +3
In this work, we investigate the cosmological consequences of an effective CDM model emerging from the more general gravity theory under the special equation-of-state c…
Beyond CDM: Exploring a Dynamical Cosmological Constant Framework Consistent with Late-Time Observations
Archana Dixit, Manish Yadav, Anirudh Pradhan +1
In this work, we investigate a cosmological scenario with a time-dependent cosmological constant (t) within the spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) framewo…
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 $…
Transit dark energy cosmological models in generalized matter-geometry coupling theory using a non-linear form of function
Dinesh Chandra Maurya, Rashid Zia
We have investigated the cosmological consequences of the model in the recently developed gravity theory [Haghani and Harko, \textit{Eur. Phys. J. C} \textbf{81} (2021) 615.] using…
Anisotropic cosmology using observational datasets: exploring via machine learning approaches
Vinod Kumar Bhardwaj, Manish Kalra, Priyanka Garg +1
In the current study, we present the observational data constraints on the parameters space for an anisotropic cosmological model of Bianchi I type spacetime in general relativity…
Dark Energy Behavior from Static Equation of State in Non-Minimally Coupled Gravity with Scalar Deformation
N. Myrzakulov, S. H. Shekh, S. R. Bhoyar +1
In this study, we explore the cosmological implications of a modified gravity theory characterized by the function \( f(R, Σ, T) \), where \( R \) is the Ricci scalar, \( Σ\) repre…
