Proposal Type: General Category: Sub-Category: Observation Category: Total Time Requested: Minimum Useful Time: Prop osal Title: ABSTRACT:
We propose to conduct targeted L-band wide observations of HI candidates without optical counterparts detected by the ALFALFA survey including: (1) high quality ALFALFA detections without optical counterparts and not associated with known tidal debris fields: the "dark galaxy" candidates; and (2) low velocity (cz <1000 km/s), low signal-to-noise, narrow HI line width ALFALFA sources without optical counterparts: the high hydrogen mass to luminosity ratio low mass dwarf galaxy candidates. The ob jectives of the LBW observations are to confirm the reality of the (almost) "dark" galaxies and possible local extreme dwarf systems so that the most intriguing cases can be targeted for coordinated multiwavelength observations to probe more deeply their dark matter and complete baryon contents. This third installment of our LBW followup campaign focuses on spring targets in newly catalogued areas. The observations will be conducted by members of the Undergraduate ALFALFA team on site.
