Dynamical Oscillations in Dark Energy: Joint Constraints on the CDM Model from DESI, OHD, and Supernova Samples
Manish Yadav, Archana Dixit, M. S. Barak +1
In this study, we investigate the oscillatory dark energy model based on the DESI BAO data together with OHD, Pantheon Plus, and SH0ES measurements. We exami…
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…
