... These observations are a precursor to a large scale, extragalactic, Zone of Avoidance (ZOA) survey with the Arecibo L-band Feed Array (ALFA). ... Full survey observations, which will begin in 2007, will reveal local large scale structure in a part of the extragalactic sky that is relatively unexplored due to the obscuration of optical light by dust in our Galaxy. ... Figure 3 Spectrum of a previously unknown galaxy from the precursor observations. Figure 4 HI Image of the galaxy from Figure 3. ...

For each galaxy, the maximum accessible volume was calculated and a binned HI mass function was computed using the 1/ V(max) method. Preliminary results suggest a galaxy detection rate which is a factor of 2-3 times higher than expected from the local HI mass function derived from HIPASS (Zwaan et al. ...

... L. Staveley-Smith (U. Western Australia) Introduction The Arecibo L-band Feed Array Zone of Avoidance Survey (ALFA ZOA) will map 1350-1800 deg2 at low Galactic latitude, providing HI spectra for galaxies in regions of the sky where our knowledge of local large scale structure remains incomplete, owing to obscuration from dust and high stellar confusion near the Galactic plane. ... Why survey the ZOA in HI? ... Results 72 galaxies detected in the 140 deg2 of sky covered by precursor observations. ...

... The obscuration due to dust and the high stellar density in our Galaxy blocks our optical view of the extragalactic Universe over 20% of the sky, somewhat less in the infrared, the "Zone of Avoidance" (ZOA). ... Mapping hidden galaxies over a range of redshifts also allows the connectivity in three dimensions of large-scale structures across the Galactic plane to be explored. ... 9 Galaxies were uncovered in this precursor region, 6 previously known from HIZOA, and 3 new HI detections. ...
