Description
Measurements of galaxy cluster kinematics have the potential to provide constraints in dark modeling and a unique constraint on baryon density in an intercluster medium. This work uses a 1-point statistical detection of the kSZ signal in ACTPol DR4 maps. To obtain the kSZ signal, we perform aperture photometry on BOSS NORTH and Deep 56 regions of ACTPol DR4 using galaxy cluster positions from DESI Legacy Survey Imager Data Release 8. With the kSZ signal, we estimate the velocity dispersion of the galaxy cluster.
