Outlying H II regions in H I-selected galaxies.

ADC_Keywords: Galaxies, radio ; H II regions 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 (>2xr25 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. Description: We searched for ELdots (emission-line point sources) in the SINGG (Survey for Ionization in Neutral Gas Galaxies) Release 1 (SR1) imaging data presented by Meurer et al. (2006, Cat. J/ApJS/165/307). File Summary:

Note (1): HST04 is imaging with the high-resolution channel, and in the case of J2352-52, revealed an obvious background galaxy. Exposure times and HST run information are given in Werk et al. (2008). Note (2): Emission lines as follows: Halpha = star formation associated with the SINGG galaxy (outer-HII) [O III] = falling within the Hα bandpass indicates a source redshift of approximately 0.3 [O II] = a redshift of 0.76 Hbeta = a redshift of ∼0.4 Note (3): Morphological classification as follows: Solo = solitary system Comp = having companions Int = interacting

Note (1): due to resolution discrepancies between SINGG images (1.5") and GALEX images (4.5") multiple ELdots are detected as single sources in the GALEX images. We have delineated affected sources by the horizontal lines in the table. The GALEX image for J0403-43 comes from the Nearby Galaxy Atlas (NGA), and has FUV and NUV exposure times of 2370s.
