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. Whi…

Modeling nonlinear scales with COLA: preparing for LSST-Y1
Jonathan Gordon, Bernardo F. de Aguiar, João Rebouças +5
Year 1 results of the Legacy Survey of Space and Time (LSST) will provide tighter constraints on small-scale cosmology, beyond the validity of linear perturbation theory. This heig…

Early dark energy constraints with late-time expansion marginalization
João Rebouças, Jonathan Gordon, Diogo H. F. de Souza +5
Early dark energy (EDE) is an extension to the CDM model, proposed to reduce the tension between the measurements of the Hubble constant from the cosmic microwave backgrou…
