Full description

Taking advantage of the high survey efficiency of the Australian Square Kilometre Array Pathfinder (ASKAP), the pilot survey of Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY; Koribalski+ 2020Ap&SS.365..118K) has been targeting nearby clusters and groups. In this study, we use its second internal data release of the Hydra cluster. WALLABY mapped a 60deg^2^ area around the Hydra cluster center, reaching out to 4r_200_ and fully covering the region within 2r_200_. The WALLABY observation reached a targeted sensitivity of {sigma}_cube_=2.0+/-0.5mJy/beam, with a circular beam FWHM of b_maj_~30" (~7kpc at the distance of Hydra) and a velocity spectral resolution of 4km/s. We use the optical g- and r-band images from the second data release of Pan-STARRS (Waters+ 2020ApJS..251....4W) to derive optical properties. The Hydra cluster has a distance of 47.5+/-3Mpc and based on X-ray data, has a radius r_200_~1.35Mpc, and a mass within this radius, M_200_~3.02x10^14^M_{sun}_ (Reiprich & Bohringer 2002ApJ...567..716R). Its velocity dispersion {sigma}_C_=620km/s is derived from M_200_ using the equation of Evrard+ (2008ApJ...672..122E).
