Abstract (from CDS):
We present a weak-lensing analysis of the Coma Cluster using the Sloan Digital Sky Survey Data Release 5. Complete imaging of an ∼200 deg2 region is used to measure the tangential shear of this cluster. The shear is fit to a Navarro, Frenk, & White model, and we find a virial radius of r200=1.99+0.21–0.22 h–1 Mpc, which corresponds to a virial mass of M200=1.88+0.65–0.56x1015 h–1 M☉. We additionally compare our weak-lensing measurement to the virial mass derived using dynamical techniques and find that they are in agreement. This is the lowest redshift, largest angle weak-lensing measurement of an individual cluster to date.
