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

In this work, we revisit the generalized emergent dark energy model by confronting it with DESI DR2 baryon acoustic oscillation measurements, in combination with joint CMB data fro…

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…

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…

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…

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…

Probing Generalized Emergent Dark Energy with DESI DR2

Vipin kumar Sharma, Himanshu Chaudhary, Sanved Kolekar

As an update on the initial findings of DESI, the new results provide the first hint of potential deviations from a cosmological constant (), which, if confirmed with signifi…
