dc.description.abstractWe present the results of Giant Metrewave Radio Telescope (GMRT) observations of the interacting system Arp86 in both neutral atomic hydrogen, H i, and in radio continuum at 240 606 and 1394 MHz. In addition to H i emission from the two dominant galaxies, NGC 7752 and NGC 7753, these observations show a complex distribution of H i tails and bridges due to tidal interactions. The regions of highest column density appear related to the recent sites of intense star formation. H i column densities ∼1–1.5 × 1021 cm−2 have been detected in the tidal bridge which is bright in Spitzer image as well. We also detect H i emission from the galaxy 2MASX J23470758+2926531, which is shown to be a part of this system. We discuss the possibility that this could be a tidal dwarf galaxy. The radio continuum observations show evidence of a non-thermal bridge between NGC 7752 and NGC 7753, and a radio source in the nuclear region of NGC 7753 consistent with it having a low-ionization nuclear emission region nucleus.en
