Is Dark Energy Dynamical in the DESI Era? A Critical Review
Salvatore Capozziello, Himanshu Chaudhary, Tiberiu Harko +1
We investigate whether the recent DESI DR2 measurements provide or not evidences for dynamical dark energy by exploring the CDM model and its extensions with free $\sum m_ν…
Evidence of dynamical dark energy found via the DESI DR2 Lyman forest
Salvatore Capozziello, Himanshu Chaudhary, G. Mustafa +1
We present a comprehensive analysis of the cosmological implications of the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (DR2) Lyman- forest baryon acoustic oscill…
Probing departures from CDM by late-time datasets
Himanshu Chaudhary, Vipin Kumar Sharma, Salvatore Capozziello +1
Observational data play a pivotal role in identifying cosmological models that are both theoretically consistent and empirically viable. In this work, we investigate the level of p…
Is the CDM Model in Crisis?
Himanshu Chaudhary, Salvatore Capozziello, Subhrat Praharaj +2
We present strong evidence for dynamical dark energy that challenges the standard CDM model. Several dark energy scenarios are explored, including CDM, logarithmic, expo…
Evidence for evolving dark energy from DESI DR2 BAO and Pantheon, DES-Dovekie, and Union3
Himanshu Chaudhary, Salvatore Capozziello, Vipin Kumar Sharma +2
Evidences for evolving dark energy are shown using baryon acoustic oscillation measurements from the recent Dark Energy Spectroscopic Instrument Data Release 2 , combined with diff…
Does DESI DR2 challenge CDM paradigm ?
Himanshu Chaudhary, Salvatore Capozziello, Vipin Kumar Sharma +1
Although debate on DESI DR1 systematics remains, DESI DR2 is consistent with DR1 and strengthens its trends. In our analysis, the LRG1 point at and the LRG…
Compact Objects in 4D Einstein Gauss Bonnet Gravity A Data Based Perspective
Puja Mukherjee, Himanshu Chaudhary, Ujjal Debnath +1
Cosmic evolution is the most sensational topic among researchers of modern cosmology. This article explores cosmic evolution in 4D Einstein Gauss Bonnet gravity, focusing on mass a…
f(R, , T) Gravity: Cosmological Implications and Dynamical System Analysis
Ratul Mandal, Himanshu Chaudhary, Tiberiu Harko +2
We consider the cosmological implications of a four-dimensional extension of the Gauss-Bonnet gravity, where is the Gauss-Bonnet topological invariant, in which the Eins…
