Scientific paper

Using data on galaxy clusters from the Abell catalog taken from the Sloan Digital Sky Survey, a mass profile using the galaxies’ positions and radial velocities is determined. This is accomplished using the timing argument discussed in Sandage (1961). The mass profile includes structures between the virial radius and the infall turnaround radius. There are around 40 clusters included in the study, ranging from redshifts of 0.05-0.2.
