Shapley Supercluster Survey: Ram-pressure stripping versus tidal interactions in the Shapley supercluster

Merluzzi, Paola; Busarello, Gianni; Dopita, Michael; Haines, C.P.; Steinhauser, D; Bourdin, H; Mazzotta, P


We present two new examples of galaxies undergoing transformation in the Shapley supercluster core. These low-mass (M⋆∼0.4--1×1010M⋆∼0.4--1×1010 M⊙) galaxies are members of the two clusters SC 1329−313 (z ∼ 0.045) and SC 1327−312 (z ∼ 0.049). Integral-field spectroscopy complemented by imaging in the ugriK bands and in Hα narrow band is used to disentangle the effects of tidal interaction (TI) and ram-pressure stripping (RPS). In both galaxies, SOS 61086 and SOS 90630, we observe one-sided...[Show more]
