Data Release: SIDM Concerto: Compilation and Data Release of Self-interacting Dark Matter Zoom-in Simulations

SIDM Concerto Data Release

• Particle snapshots, Rockstar + consistent-trees (RCT) and Symfind halo catalogs, and parametric model predictions are provided for the SIDM Concerto suite.

• The RCT tree*.dat files are too large to upload here; please contact the authors if you are interested in using these.

• For Halo962, Symfind catalogs and particle snapshots are too large to upload here; please contact the authors if you are interested in using these. 

•  For Halo004, we omit data that is already available at https://doi.org/10.5281/zenodo.14666735.

• The Symfind catalogs can be read with the following code: https://github.com/DemaoK/Concerto

• A spreadsheet with information for each simulation can be found here: https://docs.google.com/spreadsheets/d/1uOdNWPu1NCE5cWNpvhaTlEWlLGrgPJBpRUzRXVGLTps/edit?usp=sharing
