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…
No preference for generalized emergent dark energy from current cosmological data
Vipin Kumar Sharma, Himanshu Chaudhary, Salvatore Capozziello +2
The paper tests the generalized emergent dark energy (GEDE) model against recent BAO, CMB, and supernova data and finds it statistically indistinguishable from the standard ΛCDM mo…
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 oscil…
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…
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…
CDM Model: Cosmological Implications and Dynamical System Analysis
Himanshu Chaudhary, Ratul Mandal, Masroor Bashir +2
We investigated a time-varying cosmological constant model using recent BAO measurements from DESI DR2, combined with Type Ia supernova samples (Pantheon, DES-Dovekie, and Un…
