Data Release: COZMIC. I. Cosmological Zoom-in Simulations with Initial Conditions Beyond CDM

COZMIC I Simulation Data

-- Files are labeled by the host halo number (Halo004, Halo113, Halo023), DM model (WDM, FDM, IDM), and parameter for each model (mwdm for WDM, mfdm for FDM, and midm + envelope or halfmode for IDM), e.g. Halo004_wdm_mwdm_*.tar, Halo113_idm_midm_method_*.tar

-- halos.tar files include the z = 0 Rockstar halo list and the consistent-trees merger tree files 

-- particles.tar files include the z = 0 Gadget-2 snapshot blocks

-- sim_data.bin contains the host halo main branch (entry 0), isolated halos (entry 1), and subhalos (entry 2) for all models

-- All data is at the fiducial resolution presented in Paper I (Nadler et al. 2024) (particle mass 3e5 Msun/h, softening 170 pc/h)

-- A spreadsheet with information for each simulation can be found here (see the COZMIC I tab)

-- Related data products can be found here: COZMIC II (https://zenodo.org/records/14663119), COZMIC III (https://zenodo.org/records/14666735)
