Title: Dissecting ram-pressure stripping through integral-field spectroscopy of cluster spirals Abstract: We present IFU spectroscopy and H-alpha imaging of three spirals from the Shapley supercluster at z=0.048, each manifesting various effects of ongoing ram-pressure stripping as they pass through the dense intra-cluster medium. In each case we find one-sided extra-planar ionized gas being stripped from the spiral galaxy, which may be partially aided by tidal interactions with other supercluster galaxies. We resolve the impact of ram pressure on the intersteller medium and star formation, revealing a starburst on the leading edge due to compression of the interstellar gas, while star formation on the trailing side has been recently quenched. We discuss the promise of IFU spectrographs such as MUSE for understanding the physical processes behind the SF-density relation.
