N-body simulations with Arepo calibrate the ฮฒ parameter in the SIDM gravothermal model, showing it is independent of cross-section, concentration, and mass for velocity-independent scattering, and introduce an effective ฮฒ model for the long-mean-free-path regime.
This halo hasparameters ๐200๐ = 1010.56, ๐200๐ = 9.20,and ห๐ = 0.088, placing it well within the range of parameters we tested

Calibrating the SIDM Gravothermal Catastrophe with N-body Simulations
N-body simulations with Arepo calibrate the ฮฒ parameter in the SIDM gravothermal model, showing it is independent of cross-section, concentration, and mass for velocity-independent scattering, and introduce an effective ฮฒ model for the long-mean-free-path regime.
