Abstract:
We report on the properties of a sample of ultraviolet-luminous
galaxies (UVLGs) selected by matching the Galaxy Evolution Explorer
(GALEX) All-Sky Imaging and Medium Imaging Surveys with the Sloan
Digital Sky Survey third data release. The overlap between these two
surveys is roughly 450deg2. Of 25362 galaxies (with SDSS
spectroscopy) in the range 0.0<z<0.3 detected by GALEX, there are
215 galaxies with L>2x1010L☉ at 1530Å (observed
wavelength).
Description:
In this paper we make use of the GALEX All-Sky Imaging Survey (AIS)
and Medium-deep Imaging Survey (MIS). The data were taken from the
first public release of GALEX data (GR1) available at the Multimission
Archive at Space Telescope (MAST). Details on the GALEX mission and
surveys are given in Martin et al. (2005ApJ...619L...1M 2005ApJ...619L...1M). GALEX
catalogs were then matched to the SDSS third data release (DR3;
Abazajian et al. (2005, Cat. II/259) spectroscopic sample.
