An analysis of the radio properties of Lyman Break Galaxies in the COSMOS field is presented. There are 6457 U-Dropouts, 1447 B-Dropouts, and 614 V-Dropouts in this field. The percentage of radio loud AGN in Lyman Break Galaxies is found to be around 0.3% for all dropouts, in good agreement with previously measured values by Shapley et al. (2003). A stacking analysis is performed on the data sets for each of the dropouts, and an average flux density for each dropout is found. Average star formation rates and dust extinctions are derived using these average values. The U-dropouts had a median radio flux density of 0.90 microJy with an RMS of 0.21 microJy, which leads to an average star formation rate of 13.5 Msun/year, and an average dust extinction of 5. The B-dropouts had a median radio flux density of 0.83 microJy with an RMS of 0.42 microJy, which leads to an average SFR of 23.65 Msun/year and a dust extinction of 9. Finally, the V-Dropouts had a median radio flux density of 1.72 microJy with an RMS of 0.68 microJy. This leads to an average SFR of 80.64, and a dust extinction of 25. By reaching sub-microJy sensitivity at 1.4 GHz, we are able to do SKA science without the SKA. This work was done thanks to funding from the NSF and NRAO.
