Abstract:
The amount of H2 present in spiral galaxies remains uncertain,
particularly in the dim outer regions and in low-metallicity
environments. We present high-resolution CO(1-0) observations with
the Plateau de Bure interferometer of the most distant molecular cloud
in the local group galaxy M33. The cloud is a single entity rather
than a set of smaller clouds within the broad beam of the original
single-dish observations. The interferometer and single-dish fluxes
are very similar and the line widths are indistinguishable, despite
the difference in beamsize.
