New catalogue of Wolf-Rayet galaxies and high-excitation extra-galactic   HII regions
  We present a new compilation of Wolf-Rayet (WR) galaxies and extra-galactic HII regions showing BROAD HeII emission drawn from the literature. Relevant information on the presence of other broad emission lines (NIII 4640, CIV 5808 and others) from WR stars of WN and WC subtypes, and other existing broad nebular lines is provided. In total we include 139 known WR galaxies. Among these, 57 objects show both broad HeII and CIV features. In addition to the broad (stellar) HeII emission, a NEBULAR HeII component is well established (suspected) in 44 (54) objects. We find 19 extra-galatic HII regions without WR detections showing nebular HeII emission. The present sample can be used for a variety of studies on massive stars, interactions of massive stars with the ISM, stellar populations, starburst galaxies etc. The data is accessible electronically and will be updated periodicaly.
