Constraints on Spatial Curvature and Dark Energy Dynamics in the CDM Model from DESI DR1 and DR2
Manish Yadav, Archana Dixit, M. S. Barak +1
In this study, we investigate the CDM dynamical dark energy model with spatial curvature utilizing the recently released DESI Collaboration data (DR1 and DR2) in conjunction wit…
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…
Empirical Validation: Investigating the CDM Model with new DESI BAO Observations
Manish Yadav, Archana Dixit, Anirudh Pradhan +1
The CDM model has long served as the cornerstone of modern cosmology, offering an elegant and successful framework for interpreting a wide range of cosmological observations. Ho…
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…
Joint Analysis of Constraints on f(R) Parametrization from Recent Cosmological Observations
Darshan Kumar, Praveen Kumar Dhankar, Saibal Ray +1
In this study, we present constraints on the parameters of three well-known gravity models, viz. (i) Hu-Sawicki, (ii) Starobinsky, and (iii) ArcTanh by using a joint analysi…
