Model-Independent Probe of Cosmic Distance Duality Relation
Savita Gahlaut
In this paper, cosmic distance duality relation is probed without considering any background cosmological model. The only \textit{a priori} assumption is that the Universe is descr…
Testing Linearly Coasting Cosmology by Strong Lensing System and Pantheon+ Data
Savita Gahlaut
The standard model of cosmology (CDM) is facing a serious crisis caused by the inconsistencies in the measurements of some fundamental cosmological parameters (Hubble constant $…
Gamma Rays Bursts: A Viable Cosmological Probe?
Darshan Kumar, Nisha Rani, Deepak Jain +2
In this work, our focus is on exploring the potential of current GRB measurements to provide reliable constraints on cosmological model parameters at high redshift. This work is di…
Revisiting the epoch of cosmic acceleration
David Dahiya, Deepak Jain
We revisit the epoch of cosmic speed-up characterized by the redshift of transition from a decelerated to an accelerated phase. This redshift is termed the transition redshift ($z_…
Constraints on the transition redshift from the calibrated Gamma-ray Burst - correlation
Marco Muccino, Orlando Luongo, Deepak Jain
We constrain the deceleration-acceleration epoch, namely the transition redshift , adopting model-independent techniques that utilize a calibrated -…
Constraints on the Transition Redshift using Hubble Phase Space Portrait
Darshan Kumar, Deepak Jain, Shobhit Mahajan +2
One of the most significant discoveries in modern cosmology is that the universe is currently in a phase of accelerated expansion after a switch from a decelerated expansion. The r…
