Quillen et al. and O'Dea et al. carried out a Spitzer study of a sample of 62brightest cluster galaxies (BCGs) from the ROSAT Brightest Cluster Samplechosen based on their elevated H-alpha flux. We present Hubble Space TelescopeAdvanced Camera for Surveys (ACS) far ultraviolet (FUV) images of the Ly-alphaand continuum emission of the luminous emission-line nebulae in 7 BCGs found tohave an infrared excess. We confirm that the BCGs are actively forming starssuggesting that the IR excess seen in these BCGs is indeed associated with starformation. The FUV continuum emission extends over a region of ~7-28 kpc(largest linear size) and even larger in Ly-alpha. The young stellar populationrequired by the FUV observations would produce a significant fraction of theionizing photons required to power the emission line nebulae. Star formationrates estimated from the FUV continuum range from ~3 to ~14 times lower thanthose estimated from the IR, however both the Balmer decrement in the centralfew arcseconds and detection of CO in most of these galaxies imply that thereare regions of high extinction that could have absorbed much of the FUVcontinuum. Analysis of archival VLA observations reveals compact radio sourcesin all 7 BCGs and kpc scale jets in Abell 1835 and RXJ 2129+00. The fourgalaxies with archival deep Chandra observations exhibit asymmetric X-rayemission, the peaks of which are offset from the center of the BCGs by ~10 kpcon average. A low feedback state for the AGN could allow increased condensationof the hot gas into the center of the galaxy and the feeding of star formation.
