astro-claire/arepo-clusters: First catalog release

These cataogs contain simulated object properties derived from a suite of AREPO cosmological simulations of small scale structure formation in a cosmological volume. The simulations and star cluster properties are discussed in detail in Williams et al (2025). The dark matter halos in the same box are additionally provided below, corresponding to the dark matter primary, gas and stars secondary structures from that work. The available catalogs in each hdf5 file are 'redshift_12', 'redshift_13', 'redshift_14', 'redshift_15', corresponding to the four simulation snapshots analyzed for this work. The first set of catalogs, "starcluster_data.hdf5", is the same data as the "stars and gas primary" dataset from Williams et al. (2025). The following properties are available for the star clusters: stellarMass (Msun): Stellar mass (in solar masses). gasMass (Msun): Gas mass (in solar masses). virialized: Virialization status of object: 1 if virialized, 0 if not. radius_hm (kpc): Half mass radius of object (in kpc). DMMass_<r (Msun): Mass of DM contained within either virial radius (if virialized) or FOF output radius (if not virialized) (in solar masses). We additionally provide a the properties of the dark matter halos in the simulation, under "dmhalo_data.hdf5". Please refer to Williams et al (2025) for a detailed discussion of the difference between structures identified as DM halos and as star clusters. The halo catalog contains slightly different properties: DMMass (Msun): Dark matter mass (in solar masses). stellarMass (Msun): Stellar mass (in solar masses). gasMass (Msun): Gas mass (in solar masses). virialized: Virialization status of object: 1 if virialized, 0 if not. radius (kpc): Halo radius defined by (in kpc).
