Comparative Study of Gravity Models with Observational Constraints from \textit{OHD} and \textit{Pantheon+ datasets}

Anirudh Pradhan, S. A. Salve, V. B. Raut +1

The late-time acceleration of the universe remains one of the most significant open problems in modern cosmology. Modified gravity frameworks such as gravity provide a geome…

Observational tests of the conformal osculating Barthel-Kropina cosmological model

Himanshu Chaudhary, Rattanasak Hama, Tiberiu Harko +2

We consider detailed cosmological tests of dark energy models obtained from the general conformal transformation of the Kropina metric, representing an -type Finslerian geom…

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…

Generalized Second Law and Thermodynamical Aspects of Gravity

Anirudh Pradhan, A. Husain, M. Zeyauddin +1

Late-time cosmic acceleration has motivated the exploration of various extensions of general relativity, among which gravity, based on the non-metricity scalar $…

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…

Optical, Dynamic and Topological Characteristics of Deformed Schwarzschild Black Holes

Dhruba Jyoti Gogoi, Jyatsnasree Bora, Filip Studnička +1

We investigate the temperature, photon and shadow radii, quasinormal modes (QNMs), time domain profiles, greybody factors, emission rates and topological characteristics of deforme…
