Proposal Title: Completing the HI observations of late-type galaxies in the Virgo cluster
ABSTRACT:
We aim to obtain Hi detections or signicant upper limits (rms0.2-0.4 mJy at 5 km/s resolution) for a complete
sample of 30 late-type galaxies in the Virgo cluster. These comprise all of the 118 late-type galaxies selected from
an optically complete sample by the ISO consortium that were not observed, or detected, in Hi. The existing 21-cm
line data for these 30 objects have an rms noise level of about 1 mJy, which we aim to improve signicantly,
resulting in an estimated 3 detection limit of about 6 10 6 M at D=17 Mpc, i.e. MHI /LB0.1 M /L;B for the
average Im-type galaxy in the sample. For the sample of 118 ISO objects complementary integrated photometry
exists from the UV to the centimetric radio continuum in our online GOLDMine database.
