A Self-Calibrating Halo-Based Galaxy Group Finder: Algorithm and Tests

By Jeremy Tinker at
LogoNew York University
We describe an extension of the halo-based galaxy group-finding algorithm. We add freedom to the algorithm in order to more accurately determine which galaxies are central and which are satellites, and to provide unbiased estimates of halo masses. We focus on determination of the galaxy-halo relations for star-forming and quiescent... Show more
