Abstract:
In this paper we present the first results of a deep spectroscopic
survey of faint quasars in the Sloan Digital Sky Survey (SDSS)
Southern Survey, a deep survey carried out by repeatedly imaging a
270°2 area. Quasar candidates were selected from the deep data
with good completeness over 0<z<5 and 2-3mag fainter than the SDSS
main survey. Spectroscopic follow-up was carried out on the 6.5m MMT
with Hectospec. The preliminary sample of this SDSS faint quasar
survey (SFQS) covers ∼3.9°2, contains 414 quasars, and reaches
g=22.5.
Description:
The spectroscopic observations were carried out on the 6.5m MMT with
Hectospec in 2004 June (run I) and 2004 November (run II).
