Introducing the DREAMS Project: DaRk mattEr and Astrophysics with Machine learning and Simulations

Understand

We introduce the DREAMS project, an innovative approach to understanding the astrophysical implications of alternative dark matter models and their effects on galaxy formation and evolution.

• The DREAMS project will ultimately comprise thousands of cosmological hydrodynamic simulations that simultaneously vary over dark matter physics, astrophysics, and cosmology in modeling a range of systems -- from galaxy clusters to ultra-faint satellites.
• Such extensive simulation suites can provide adequate training sets for machine-learning-based analyses.
• This paper introduces two new cosmological hydrodynamical suites of Warm Dark Matter, each comprised of 1024 simulations generated using the Arepo code.
