We present a new compilation of Wolf-Rayet (WR) galaxies
and extra-galactic Hiiregions showing broad
emission
drawn from the literature.
Relevant information on the presence of other broad emission lines (N iii
λ4640, C iv
λ5808 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
and C iv
λ5808 features. In addition to the broad (stellar)
emission, a nebular He ii component is well established
(suspected) in 44 (54) objects.
We find 19 extra-galatic Hii regions without WR detections showing
nebular
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 periodically.
Key words: galaxies: starburst / galaxies: stellar content / galaxies: ISM / stars: Wolf-Rayet
