Hu-Sawicki Gravity in a Non-Flat Universe: Constraints from DESI-DR2, BBN, and Type Ia Supernovae
Saurabh Verma, Manish Yadav, Archana Dixit +2
Late-time cosmic acceleration is conventionally ascribed to a cosmological constant, though CDM continues to face several theoretical difficulties that keep alternative gravity…
Testing a Sign-Switch Cosmological Model with Curvature through Latest Planck 2018, DESI DR2 and PantheonPlus\&SH0ES Observational Data
Archana Dixit, Manish Yadav, Anirudh Pradhan +1
We investigate the spatial geometry of the Universe within the framework of a sign-switch dark energy scenario by extending the recently proposed CDM model to include a…
Testing Exponential Gravity with CMB, DESI-DR2, and Supernova Data
Saurabh Verma, Archana Dixit, Anirudh Pradhan +1
One of the most popular competitors to the CDM paradigm as an explanation for the late-time acceleration of the universe is the modification of general relativity (GR), with models…
Alleviating the Hubble Tension with Logarithmic Dark Energy: Constraints on the CDM Model
Saurabh Verma, Archana Dixit, Anirudh Pradhan +1
Observational constraints are considered on a CDM model of the dark energy equation of state, , using…
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…
Cosmological Implications of a New Creation Field in Hoyle-Narlikar Gravity with Bulk Viscous Fluid
Manish Yadav, Archana Dixit, Anirudh Pradhan +1
In this study, we present a comprehensive investigation of the Narlikar gravity model with bulk viscous fluid by the new foam of creation field ,…
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…
