Data Release: The Effects of Linear Matter Power Spectrum Enhancement on Dark Matter Substructure

Enhanced P(k) Simulation Data -- Files are labeled by the host halo number and presence/absence of a bump ("bump") or cutoff ("cutoff") in the linear matter power spectrum, e.g. Halo004_Tkd_T_vd100_*.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_enhanced_16K.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 high resolution presented in Nadler, Gluscevic, & Benson (2025) (particle mass 5e4 Msun, softening 80 pc/h) -- A spreadsheet with information for each simulation can be found here. -- Related data products can be found here: COZMIC I (10.5281/zenodo.14649137), COZMIC II (10.5281/zenodo.14663119), COZMIC III (10.5281/zenodo.14666735)
