Conformal Killing Gravity: New Constraints from DESI DR2 BAO datasets
Himanshu Chaudhary, Salvatore Capozziello, Carlo Alberto Mantica +3
We investigate a geometric approach referred to as the Conformal Killing Gravity (CKG), in which the dark energy sector emerges naturally from the conformal Killing symmetry of the…
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…
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…
Observational Constraints on the Parameters of Hořava-Lifshitz Gravity
Himanshu Chaudhary, Ujjal Debnath, Shibesh Kumar Jas Pacif +3
This study investigates the accelerated cosmic expansion within the Hořava-Lifshitz Model. To constrain the cosmological parameters of this model, we incorporate 17 Baryon Acoustic…
Extracting and in Pacif Parametrization Models through Late-Time Dataset
Himanshu Chaudhary, Shibesh Kumar Jas Pacif, G. Mustafa +2
This study examines five models derived from the Pacif parametrization scheme of the Hubble parameter (), yielding various linear to quintic forms of the deceleration parameter…
