GALEX selected Lyman Break Galaxies at z~2: Comparison with other
  Populations
  We present results of a search for bright Lyman break galaxies at 1.5<=z<=2.5
in the GOODS-S field using a NUV-dropout technique in combination with
color-selection. We derived a sample of 73 LBG candidates. We compare our
selection efficiencies to BM/BX- and BzK methods (techniques solely based on
ground-based data sets), and find the NUV data to provide greater efficiency
for selecting star-forming galaxies. We estimate LBG candidate ages, masses,
star formation rates, and extinction from fitting PEGASE synthesis evolution
models. We find about 20% of our LBG candidates are comparable to infrared
luminous LBGs or sub-millimeter galaxies which are thought to be precursors of
massive elliptical galaxies today. Overall, we can show that although BM/BX and
BzK methods do identify star-forming galaxies at z~2, the sample they provide
biases against those star-forming galaxies which are more massive and contain
sizeable red stellar populations. A true Lyman break criterion at z~2 is
therefore more directly comparable to the populations found at z~3, which does
contain a red fraction.
