The COLIBRE simulations and their properties are listed in the tables below. The columns list the simulation identifier (where L is followed by the side length of the cubic simulation volume in comoving Mpc; m is followed by the rounded log10 of the mean particle mass in solar masses (for both baryons and DM); h indicates hybrid AGN feedback); the comoving box side length, L; the number of baryonic particles, Nb; the number of CDM particles, NCDM; the initial mean baryonic particle mass, mg; the mean CDM particle mass, mCDM; the Plummer-equivalent comoving gravitational softening length, εcom; the maximum proper gravitational softening length, εprop.

For each hydrodynamic simulation, there is a corresponding DMO simulation that uses the same initial phases and the same total number of particles. To create the initial conditions for the DMO simulation, baryonic particles from the corresponding hydrodynamic run were converted into CDM particles.
The interactive plot below shows cumulative galaxy and stellar mass functions. The lower limit on the horizontal axis correponds to 100mg for that run.
