Intergalactic star formation Duc, P.-A. Boquien, Mérédic Braine, J. Brinks, E. Lisenfeld , Ute Charmandaris, V. Galaxies Star formation NGC 5291 Star formation in interacting systems may take place in various locations, from the dust--enshrouded core of Ultraluminous Infrared Galaxies to more unusual places such as the debris of colliding galaxies expelled into the intergalactic medium. Determining whether star-formation proceeds in the latter environment, far from the parent galaxies, in a similar way as in spiral disks has motivated the multi--wavelength study presented here. We collected VLA/HI, UV/GALEX, optical Halpha and MIR/Spitzer images of a few nearby interacting systems chosen for their prominent "intergalactic" star formation activity. Preliminary results on the spectacular collisional HI ring around NGC 5291 are presented. 2013-10-10T10:44:02Z 2013-10-10T10:44:02Z 2006 info:eu-repo/semantics/conferenceObject Duc, P.-A.; et al.
