Abstract
The properties of molecular gas in spiral galaxies is the subject of a
wide field of research and much has been done on the global scale of
galaxies. The advent and maturity of the On-The-Fly (OTF) mapping
technique at the NRAO 12m radio telescope now affords us with a way to
address many issues on the more local scales within a large number of
nearby spiral disks that are many arcminutes in diameter. We start a
project which aims at OTF mapping of the distribution of 12CO(J=1-0)
emission in spiral galaxies in the Ursa Major cluster and compare in
detail the distributions of the molecular gas to that of the neutral
hydrogen as a function of the morphological type, surface brightness,
dust content and temperature and the star formation threshold of a
galaxy's disk. We will present the first results of the OTF CO(J=1-0)
mapping of spiral galaxies in the Ursa Major cluster, obtained with the
NRAO 12m radio telescope during June 20-27, 1999 and March 23-30, 2000.
