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…

Gravitational wave lensing: probing Fuzzy Dark Matter with LISA
Shashwat Singh, Guilherme Brando, Stefano Savastano +1
Gravitational lensing is a universal phenomenon: it affects both gravitational waves (GWs) and electromagnetic signals travelling through the gravitational field of a massive objec…

Euclid preparation. Simulations and nonlinearities beyond CDM. 1. Numerical methods and validation
Euclid Collaboration, J. Adamek, B. Fiorini +268
To constrain models beyond CDM, the development of the Euclid analysis pipeline requires simulations that capture the nonlinear phenomenology of such models. We present an overv…
