The optimal redshift for dark energy II: application to cosmological data and the evidence for the phantom crossing of the CPL equation of state
Travis Seth Rippentrop, Mustapha Ishak, Kristian Gonzalez
Recent results from DESI and other cosmological datasets have indicated a preference for dynamical dark energy, with a time-evolving equation of state (EOS), . Furthermore, a…

The optimal redshift for dark energy I: formalism and interpretation
Mustapha Ishak, Travis Seth Rippentrop, Kristian Gonzalez
We introduce the concept of the optimal redshift for dark energy, a statistically motivated redshift at which departures of the dark-energy equation of state (EOS) from the cosmolo…
