Query: Lyman Break Galaxies and Luminous IR Galaxies at z ~ 1   We use deep GALEX images of CDFS in UV to define the first large sample of
420 Lyman Break Galaxies at z~1. We use a PSF fitting to estimate UV magnitudes
on these deep crowded images. Deep Spitzer IRAC and MIPS provide the first
detection of a large sample of Lyman Break Galaxies in the mid- to far-infrared
range. We are therefore able to study and compare the UV and TIR emission of
Lyman Break Galaxies. We find that about 15% of the LBG sample are strong
emitters at 24 microns (Red LBGs). Most of them are Luminous IR Galaxies
(LIRGs) while the rest (Blue LBGs) are undetected at the 83 microJy level of
MIPS GTO image. We find that Blue LBGs have a Spectral Energy Distribution
similar to high redshift Lyman Break Galaxies. Finally, the dust-to-FUV ratio
of this sample is compared with similar ratios at z=1 and z~2. This work
suggests an evolution (decrease) of the dust-to-FUV ratio with the redshift.
