Code releases and accompanying papers:

1809.05542: Modeling the Connection Between Subhalos and Satellites in Milky Way-Like Systems.

-- Implements the satellite galaxy--subhalo connection model described in the papers, which maps subhalos in dark matter-only zoom-in simulations of MW-mass halos to their corresponding satellite galaxies.

-- Contains tools for forward-modeling the population of classical and SDSS MW satellites.

1912.03303: Milky Way Satellite Census. II. Galaxy-Halo Connection Constraints Including the Impact of the Large Magellanic Cloud.

-- Implements the updated satellite galaxy--subhalo connection model described in the papers, which builds on the V1 model by including tools to analyze simulations with realistic Large Magellanic Cloud analogs.

-- Contains tools for forward-modeling the population of DES and Pan-STARRS MW satellites.

-- The healpix masks necessary to implement the DES and PS1 survey selection functions in V2 can downloaded using the following links. Please see https://github.com/des-science/mw-sats for additional information.

2401.10318: Forecasts for Galaxy Formation and Dark Matter Constraints from Dwarf Galaxy Surveys.

-- Implements the satellite galaxy--subhalo connection model and inference evaluated on mock halo catalogs, for various galaxy formation, WDM, and SHMF models

-- Improves vectorization of MCMC evaluation for MPI runs

Utils

-- Contains tools for calculating the orbits of "orphan" (disrupted) subhalos in dark matter-only simulations, which are used in the V1 and V2 analyses, and tools for computing the likelihood of a satellite galaxy--subhalo connection model given an observed satellite population.

Data

-- Contains zoom-in subhalo catalogs, abundance matching interpolator, and Milky Way satellite data

Classifier

-- Contains XGBoost satellite selection function model from 1912.03302.
