Description
We present the spectroscopic follow-up of the OmegaWINGS photometric survey, aimed at covering the outskirts of a subset of the original WINGS cluster sample. We observed 33 of the 46 clusters of galaxies observed with VST over 1 square degree. The aim of this spectroscopic survey is to enlarge the number of cluster members and study the galaxy characteristics and the cluster dynamical properties out to large radii, reaching the virial radius and beyond. We used the AAOmega spectrograph at AAT to obtain fiber-integrated spectra covering the wavelength region between 3800 and 9000{AA} with a spectral resolution of 3.5-6{AA} full width at half maximum (FWHM). We present here the redshift measurements for 17985 galaxies, 7497 of which turned out to be cluster members.
