We present Hubble Space Telescope Advanced Camera for Surveys (ACS) far ultraviolet (FUV) images of the Ly-alpha and continuum emission of the luminous emission-line nebulae in 7 BCGs found to have an infrared excess. We confirm that the BCGs are actively forming stars suggesting that the IR excess seen in these BCGs is indeed associated with star formation. The FUV continuum emission extends over a ","authors_text":"Alastair C. Edge, Alice C. Quillen, Bradford T. Snios, Christopher P. O'Dea, G. Mark Voit, Grant R. Tremblay, Jacob Noel-Storr, Kevin P.
