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…
Investigating the CDM Model with Latest DESI BAO Observations
Manisg Yadav, Archana Dixit, M. S. Barak +1
In this study, we explore the impact of various combinations of CMB-independent datasets, including the recent DESI BAO measurements, on the equation of state (EoS) of dark energy…
Testing Gravity with Cosmological Observations: Confronting the Hubble Tension and Implications for the Late-Time Universe
Saurabh Verma, Archana Dixit, Anirudh Pradhan +1
In recent years, modifications to General Relativity (GR) have been explored to address cosmological observations, particularly in the context of late-time cosmic acceleration. Amo…
Exploring the dynamics of coincident f(Q) gravity in the presence of DBI-essence scalar field
Ratul Mandal, Ujjal Debnath, Anirudh Pradhan
In theoretical cosmology, symmetric teleparallel gravity or gravity based on nonmetricity tensor Q has become an interesting alternative to General relativity in recent year…
Constraining a Gravity Cosmological Model with Observational Data
G. K. Goswami, Anirudh Pradhan, Syamala Krishnannair
We investigate a spatially flat FLRW cosmological model in the framework of modified gravity described by the function \( f(R, L_m) = αR + L_m^β+ γ\), where \( L_m \) is the matter…
Observational constraints in late time for an axially symmetric transitioning model with bulk viscous fluid
G. K. Goswami, Anirudh Pradhan, Vipin Chandra Dubey
In this paper, we explore an axially symmetric Bianchi type-I model of the universe with bulk viscous fluid as a source of gravitational field under the framework of Einstein's fie…
