GalWCat19 is a spectroscopic catalogs of 1,800 galaxy clusters and a corresponding catalog of 34,471 identified member galaxies using the GalWeight technique.  The catalog is derived from the SDSS-DR13 spectroscopic data set and each cluster was studied individually to determine its dynamical properties. 

  • The redshift space of galaxy clusters

  • Cluster dynamics codes

​

  1. identify clusters' locations from a survey (OverDenRedshift.m)

  2. identify clusters' centers (ClusterCenters.m)

  3. calculate clusters' dynamics using virial theorem and NFW model (DynamicsNFWMLE.m)
