Matching current observational constraints with nonminimally coupled dark energy
William J. Wolf, Pedro G. Ferreira, Carlos García-García
We show that a Universe with a nonminimally coupled scalar field can fit current measurements of the expansion rate of the Universe better than the standard -Cold Dark Matter ($…
Scant evidence for thawing quintessence
William J. Wolf, Carlos García-García, Deaglan J. Bartlett +1
New constraints on the expansion rate of the Universe seem to favor evolving dark energy in the form of thawing quintessence models, i.e., models for which a canonical, minimally c…
Minimizing the tensor-to-scalar ratio in single-field inflation models
William J. Wolf
We revisit a class of simple single-field inflation models and demonstrate that they can readily produce a negligible tensor/scalar ratio . Motivated by recent work suggesting t…
