Constraints on Dynamical Dark Energy from Multiple Probes in the Full Dark Energy Survey
DES Collaboration, T. M. C. Abbott, M. Adamow +166
We present results on dark energy evolution, assuming a time-dependent equation of state , from growth and geometric probes using the full six-year Dark Energy S…

The sound of dynamical dark energy and modified gravity
João Rebouças, Guilherme Brando, Felipe T. Falciano +1
Different candidate models are able to reproduce the dynamical dark energy signal preferred by combinations of recent distance measurements. These models may be distinguished by th…

Modeling nonlinear scales for dynamical dark energy cosmologies with COLA
João Rebouças, Victoria Lloyd, Jonathan Gordon +2
Upcoming galaxy surveys will bring a wealth of information about the clustering of matter, but modeling small-scale structure beyond CDM remains computationally challenging. Wh…
