Abstract
We observed the 12CO() emission of the emission-line regions Hubble I, Hubble V, Hubble X, Holmberg 18, and the stellar emission-line object S28 in NGC 6822 with the ESO Atacama Pathfinder Experiment (APEX) 12 m telescope as part of its science verification. The very low system temperature of K enabled us to achieve detections in 4 single pointings and in a high spatial resolution map of Hubble V. We compare the spectra with Hi observations, obtained with the Australia Telescope Compact Array, of the same regions. In combination with previous multi-line CO observations, we perform a preliminary investigation of the physical conditions in Hubble V using a simple LTE model. We estimate the mass of the Hubble V region and the H conversion factor. Also, we show that Hubble V is located very near the line-width versus size relation traced by the Milky Way and LMC molecular clouds.
