The First VLT FORS1 spectra of Lyman-break candidates in the HDF-S and AXAF Deep Field
S. Cristiani, I. Appenzeller, S. Arnouts +9
We report on low-resolution multi-object spectroscopy of 30 faint targets (R \~ 24-25) in the HDF-S and AXAF deep field obtained with the VLT Focal Reducer/low dispersion Spectrogr…
