Harvesting ALFALFA: L-band Wide Followup of Enigmatic ALFALFA sources

We propose to conduct targeted L-band wide observations of selected sources detected by the ALFALFA survey in four categories: (1) high quality ALFALFA detections without optical counterparts and not associated with known tidal debris fields: the "dark galaxy" candidates; (2) ALFALFA sources without optical counterparts which are candidate OH megamasers because of their coincidence with optical sources at the appropriate redshift; (3) low signal-to-noise, low velocity (nearby), narrow line width ALFALFA sources without optical counterparts: the extreme gas-dominated dwarf galaxy candidates; and (4) statistical samples of the low signal-to-noise ratio detections possibly associated with optical galaxies. The ob jectives of the LBW observations are to confirm the reality of the (almost) "dark" galaxy and OH megamaser candidate signals and to enable the extension of the ALFALFA catalog at the low HI line flux density regime for science applications that can benefit from higher source density.
