The Arecibo L-band Feed Array has been used to map a 5 square degree region out to a velocity of 18,000 km/s, covering a volume (for H0=70 km/s/Mpc) of 8900 cubic Mpc. In the region behind the NGC 7332 group, we find 40 HI sources, of which 15 are previously catalogued and 5 have previous redshift measurements. 25 sources (62.5%) are new detections, we are currently trying to identify optical counterparts for these sources. The HI sources have a median redshift of 12,000 km/s ( 170 Mpc) and range in neutral hydrogen content from 8x108 to 3x1010 solar masses.
The Arecibo Observatory is part of the National Astronomy and Ionosphere Center, which is operated by Cornell University under a cooperative agreement with the National Science Foundation.
