2MASS at UMASS the theory group

    The theory group at UMASS is involved in a number of projects using the Two Micron All Sky Survey (2MASS) to study Cosmology, Galaxy Evolution, the Local Group and the Milky Way. 2MASS is an all sky survey in the near infrafred (J, H and K_sbands). There are more than 500 million sources in the point source catalog and 1.6 million sources in the extended source catalog. The 2MASS catalogs have been made available to the public.  Below are some of the images we have produced with the 2MASS catalog as well as links to the revlevant papers. For a list of all papers that use 2MASS data look here.  Talks that members of the group have given on various topics can be found below.
