Proposal Title: The Widefield Arecibo Virgo Extragalactic Survey
ABSTRACT:
The Widefield Arecibo Virgo Extragalactic Survey (WAVES) is a neutral hydrogen (HI) survey using the Arecibo
L­band Feed Array (ALFA) that will cover almost the entire Virgo cluster north of 9 degrees to the depth reached
by the Arecibo Galaxy Environment Survey (AGES). AGES has covered a field in the Virgo cluster from 7 ­ 9
degrees north, which serves as a pilot for WAVES. The AGES observations showed that the cluster contains
numerous HI sources, including clouds without apparent optical counterparts, that are below the detection
threshold of the Arecibo Legacy Fast ALFA (ALFALFA) survey. In the Virgo cluster, WAVES will increase our
knowledge of the faint end of the HI mass function, uncover extended structures and dark clouds, and investigate
the relationship between HI richness and morphological transformation. It will also cover a volume out to z 0.15
where (as in AGES) further discoveries can be expected.
