Abstract (from CDS):

We present candidate quasars from a multicolor (uBVRI+narrowband) imaging survey of (1)/(2) square degree around the Hubble Deep Field-South (HDF-S). We identify 154 candidate quasars with B<23 using color selection, consistent with previously measured QSO number counts if we assume a 60% selection efficiency. The narrowband filter (NB) was centered at 3958 Å to detect Lyα at the redshift of J2233-6033, the HDF-S QSO. We confirm the presence of Lyα nebulosity extending ∼12" around the HDF-S QSO, reported by Bergeron and coworkers. We detect 10 pointlike objects in emission through the NB filter. Of these, seven satisfy our QSO color selection criteria. One of the emission-line objects is a B∼20 radio-quiet quasar at z=1.56, 6'.7 from the line of sight to the HDF-S QSO and ∼12" from the western edge of the WFPC2 deep field.
