An Updated Ultraviolet Catalog of GALEX Nearby Galaxies
Abstract
The ultraviolet catalog of nearby galaxies made by Gil07 presents the integrated photometry and surface brightness profiles for 1034 nearby galaxies observed by Galaxy Evolution Explorer (GALEX). We provide an updated catalog of 4138 nearby galaxies based on the latest Genral Release (GR6/GR7) of GALEX. These galaxies are selected from HyperLeda with apparent diameter larger than 1. From the surface brightness profiles accurately measured with the deep NUV and FUV images, we have calculated asymptotic magnitudes, aperture (D25) magnitudes, colors, structural parameters (effective radii and concentration indices), luminosities, and effective surface brightness. Archival optical and infrared photometry from HyperLeda, 2MASS, and IRAS are also integrated into the catalog. Our parameter measurements and some analyses are consistent with those of Gil07. The (FUV - K) color provides a good criterion to distinguish early and late-type galaxies, which can be improved further with the concentration indices. The IRX-β relation is reformulated with our UV-selected nearby galaxies.
