| Description | Understanding the processes governing the formation of clouds and stars in merging systems is key for the study of how galaxies evolved in the early Universe. The 30 Doradus region in the low-metallicity Large Magellanic Cloud (LMC) is the nearest example of this process, resulting from the interaction between the LMC and the halo of the Milky Way. This makes 30 Doradus the prime laboratory to study these large-scale dynamical processes under conditions that are similar to those at early cosmological times. We propose to use Herschel to obtain a large-scale uniform sampling of this region in CII 158um, NII 122um and 205um, and OI 63um and 146um lines with PACS, and at selected positions in CII with HIFI. With this data we will derive the large-scale distribution of the density and pressure of the low-metallicity gas revealing the characteristic signatures of shocked gas. This will then be used to determine the relationships among the diffuse, dark H2, and dense molecular gas in the 30 Doradus region. We will also derive the electron density distribution of the gas and from this the contribution from ionized gas to the observed CII emission. The proposed observations will allow us to study the effect of large-scale gas compression in the multiphase, low-metallicity interstellar medium of 30 Doradus. This information will be valuable for the interpretation of future observations of CII in high-redshift galaxies made with ALMA |

| Mission Description | Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
