CAMELS stands for Cosmology and Astrophysics with MachinE Learning Simulations, and it is a project that aims at building bridges between cosmology and astrophysics through numerical simulations and machine learning. CAMELS contains 13,013 cosmological simulations --5,112 N-body and 7,901 state-of-the-art (magneto-)hydrodynamic-- and more than 1 Petabyte of data. CAMELS is the largest set of cosmological hydrodynamic simulations ever run.

Introductory video to the CAMELS project:
The video below shows an example of a CAMELS hydrodynamic simulation run with the Ramses code. Gas density and gas temperature are shown in blue and red, respectively as a function of time. CAMELS contains thousands of simulations like this one.
The video below illustrates the differences between different hydrodynamic simulations. All simulations share the same cosmology, initial conditions, and have fiducial astrophysics values. Differences in the different fields shown are due to the intrinsic differences between the subgrid models employed in the simulatons.
