Scientific paper

The Undergraduate ALFALFA (Arecibo Legacy Fast ALFA) Team Groups Project is a collaborative undertaking of faculty and students at 11 institutions, aimed at investigating properties of galaxy groups surveyed by the ALFALFA blind HI survey. As part of this project, we are determining group memberships and developing IDL codes to estimate the corresponding dynamical masses of groups. For galaxy group AWM3, we find a group membership of 165 galaxies, which is used to compare the results from several different dynamical mass calculations. This work has been supported by NSF grants AST-0724918, AST-0725267 and AST-0725380.
