Dynamical Oscillations in Dark Energy: Joint Constraints on the $w_{sin}$CDM Model from DESI, OHD, and Supernova Samples

Manish Yadav, Archana Dixit, M. S. Barak +1

In this study, we investigate the oscillatory dark energy model $w_{\sin }\mathrm{CDM}$ based on the DESI BAO data together with OHD, Pantheon Plus, and SH0ES measurements. We exami…
