Probing generalized equation of state for dark energy with latest cosmological probes
Baryon acoustic oscillation (BAO) measurements from DESI DR2 have strengthened indications of a time-evolving dark energy. In this paper, we investigate observational constraints on the generalized equation of state (GEoS) for dark energy, $w(a) = w_0 - w_\beta (a^{\beta}- 1)/\beta$, with latest data from UV and X-ray...
