Previous radio observations of the galaxy cluster A3560 in the ShapleyConcentration showed complex radio emission associated with the brightestcluster member.To understand its origin we observed it with the GMRT, the VLAand ATCA at 240 and 610 MHz, 1.28,1.4, 2.3,4.8 and 8.4 GHz, and performed adetailed morphological and spectral study of the radio emission associated withthe BCG. We also observed the cluster with XMM-Newton and Chandra to derive theproperties of the ICM. The radio emission of the N-E nucleus of the dumb-bellBCG shows an active radio galaxy, plus aged diffuse emission, which is notrefurbished at present. Our Chandra data show that the radio active nucleus ofthe BCG has extended X-ray emission, which we classify as a low-luminositycorona. A residual image of the XMM-Newton brightness shows the presence of aspiral-like feature, which we interpret as the signature of gas sloshing. Thepresence of a subgroup is clear in the surface brightness residual map, and inthe XMM-Newton temperature analysis. The optical 2D analysis shows substructurein A3560. A galaxy clump was found at the location of the X-ray subgroup, andanother group is present south of the cluster core, close to the spiral-likefeature. The aged part of the radio emission closely follows the spiral patternof the X-ray residual brightness distribution, while the two active radio lobesare bent in a completely different direction. We conclude that the complexradio emission associated with the cluster BCG is the result of a minor mergerevent in A3560. The aged diffuse emission is strongly affected by the sloshingmotion in the ICM. On the other hand, the bent jets and lobes of the currentradio AGN activity may reflect a complex gas velocity field in the innermostcluster regions and/or sloshing-induced oscillations in the motion of the cDgalaxy.
