Outlying H II regions in H I-selected galaxies. (2010)

Keywords : galaxies halos - galaxies: star clusters - H II regions - intergalactic medium - stars: formation

Abstract:We present results from the first systematic search for outlying HII regions, as part of a sample of 96 emission-line point sources (referred to as ELdots-emission-line dots) derived from the NOAO Survey for Ionization in Neutral Gas Galaxies (SINGG). Our automated ELdot finder searches SINGG narrowband and continuum images for high equivalent width point sources outside the optical radius of the target galaxy (>2xr_25_ in the R band). Follow-up long-slit spectroscopy and deep Galaxy Evolution Explorer (GALEX) images (exposure time >1000s) distinguish outlying HII regions from background galaxies whose strong emission lines ([OIII], H{beta], or [OII]) have been redshifted into the SINGG bandpass. ...(more)
