Testing CDM versus dynamical dark energy in one year: A DESI spectroscopic follow-up program for Rubin supernovae

Jannik Truong, Greg Aldering, Saul Perlmutter +2

Combined cosmological probes currently indicate that best-fit values in the parametrization of dynamical dark energy deviate from CDM by . In this work, we p…
