ALFALFA Discovery of an HI Cloud Complex in the Virgo Cluster: Aperture Synthesis Observations

We present aperture synthesis observations of the HI cloud complex in Virgo detected by the Arecibo Legacy Fast ALFA Survey (ALFALFA, Giovanelli et al. 2005; poster 179.22). We make two detections: the first is associated with the largest cloud in the complex, while the second coincides with an ALFALFA source near the LSB galaxy VCC 1357. In both cases, the ALFALFA clouds resolve into a network of HI clumps exhibiting no ordered velocity structure. An interpretation of the observations in terms of a galaxy harassment scenario is favored.
