Lyman break galaxies at z~3 and z~4 in the Chandra Deep Field South

摘要

We present first results of a Lyman break galaxy survey in the complete 30 by 30 Chandra Deep Field South (CDFS) based on deep, multi-color CCD mosaic images. We find more than 1100 U-band and 600 B-band drop-outs, consistent with the expectations from earlier searches in smaller fields. The results of the 2-point correlation functions agree well with earlier results on smaller fields, too. Due to the full coverage of the survey field with HST-ACS images, we can study the structure of the Lyman break galaxies, which turn out to span a large range in morphologies.
