Stellar masses of Lyman break galaxies at z~3 (Magdis+, 2010)

The data for this study have been obtained with the (IRAC) on board the Spitzer Space Telescope. The majority of our data are part of the IRAC GTO program (PI G. Fazio) and include the fields: Q1422+2309 (Q1422), DSF2237a,b (DSF), Q2233+1341 (Q2233), SSA22a,b (SSA22) and B20902+34 (B0902) while data for the HDF-N come from the Great Observatories Origin Deep Survey program (GOODS, PI M. Dickinson). The data analysis and the mid-IR identification of the LBGs in these fields have been presented in detail by Magdis et al. (2008MNRAS.386...11M). Based on a catalogue of 1261 LBGs by Steidel et al. (2003, Cat. J/ApJ/592/728) in these fields, we constructed a mid-IR sample of 751 LBGs, that were observed in at least one IRAC band.
