Scant evidence for thawing quintessence

WJ Wolf, C García-García, DJ Bartlett, PG Ferreira - Physical Review D, 2024 - APS
New constraints on the expansion rate of the Universe seem to favor evolving dark energy in
the form of thawing quintessence models, ie, models for which a canonical, minimally …
