Deus ex $H_{0}$ -- Is evidence for dynamical dark energy conditioned on early cosmology?

Nils Schöneberg, Rodrigo Calderón, Julien Lesgourgues

Some free-form reconstructions of the dark energy equation of state suggest that dynamical dark energy is the only explanation for the observed data. In this letter we argue that e…

Charging Across the Phantom Divide with Modified Gravity

Rodrigo Calderon, Eric V. Linder

Cosmology where the effective dark energy crosses $w = - 1$ can be realized in Horndeski gravity with shift symmetric terms plus a linear potential. We highlight the special role of t…
