We apply two set of selection criteria to identify F275W and F336W-dropout to get a sample of 114 and 194 LBG candidates at z ~ 2.1 and z ~ 2.7 respectively. We use multi-wavelength imaging combined with available spectroscopic and photometric redshifts to carefully access the validity of our UV-dropout candidates. We divide the samples of bin size z = 0.1, and estimate LBG candidate ages, masses, and star formation rates from fitting CIGALE synthesis evolution models. We track the growth of mass and size of galaxies from z~3 to z~2. Overall, we can show that LBGs are low massed compact structures with half-light radii of only a few kpc. A true Lyman break criterion at z ∼ 2 is therefore, more directly comparable to the populations found at z ∼ 3, which contains a red fraction. |
