Scientific paper

We report interferometric mapping of RXJ0821+07. Aperture synthesis observations of the CO(1-0) and CO(2-1) line emission have been performed in this cooling flow cluster, using the PdB Millimeter Array. The inferred molecular hydrogen column densities is derived and the molecular gas mass is compared to previous 30m telescopes estimates. The morphology and the dynamics of the cold molecular gas is then discussed and compared to higher energy data. Finally, we review the implications of these results in relation with the cooling flow model expectations.
