Using the multiwavelength photometric and spectroscopic data covering theCDF-S obtained within the GOODS, we investigate the rest-frame UV properties ofgalaxies to z~2.2, including the evolution of the luminosity function, theluminosity density, star formation rate (SFR) and galaxy morphology. We find asignificant brightening (~ 1 mag) in the rest-frame 2800A characteristicmagnitude (M*) over the redshift range 0.3<z<1.7 and no evolution at higherredshifts. The rest-frame 2800A luminosity density shows an increase by afactor ~4 to z~2.2. We estimate the SFR to z~2.2 from the 1500A and 2800Aluminosities. The SFR derived from the 2800A luminosity density is almostfactor two higher than that derived from the 1500A luminosities. Attributingthis to differential dust extinction, we find that an E(B-V)=0.20 results inthe same extinction corrected SFR from both 1500A and 2800A luminosities. Weinvestigate the morphological composition of our sample by fitting Sersicprofiles to the galaxy images at a fixed rest-frame wavelength of 2800A at0.5<z<2.2. We find that the fraction of apparently bulge-dominated galaxies(Sersic index n>2.5) increases from ~10% at z~0.5 to ~30% at z~2.2. At the sametime, we note that galaxies get bluer at increasing redshift. This suggests ascenario where an increased fraction of the star formation takes place inbulge-dominated systems at high redshift. This could be the evidence that thepresent day ellipticals are a result of assembly (i.e., mergers) of galaxies atz>1. Finally, we find that galaxy sizes for a luminosity selected sampleevolves as (1+z)^{-1.1} between redshifts z=2.2 and z=1.1. This is consistentwith previous measurements and suggests a similar evolution over the redshiftrange 0 < z < 6.Comment: 38 pages with 14 figures. Accepted for publication in Ap
