The MultiDark Database provides results from cosmological simulations and lets users query its records with SQL.
CosmoSim
CosmoSim provides results from cosmological simulations, including MultiDark and Bolshoi projects and galaxy catalog data.
About CosmoSim
CosmoSim provides results from cosmological simulations from the MultiDark, Bolshoi and Galaxies projects, including MDR1, SMDPL, MDPL, MDPL2, BigMDPL, Bolshoi and BolshoiP, plus MDPL2 galaxy catalogs with galaxy properties from the Galacticus, SAG and SAGE codes. The database can be queried by entering SQL statements in the Query interface or through scripted access.
Full access to all data requires registration via the Registration Form. Users who employ the data in a scientific publication or proposal are asked to follow the acknowledgment guidance on the linked project pages. The site also collects visualizations related to the simulations.
