| Description | An increasing amount of evidence, both from radio and NIR data, seems to indicate that RCW 49, one of the most luminous and massive HII regions in the Galaxy (Paladini et al. 2003), harbors Anomalous Microwave Emission (AME). Here, we request PACS and SPIRE mapping observations of RCW49. The proposed observations will allow us to pin down the correlation of the observed microwave excess with dust emission, hence ruling out the possibility that this can be attributed to embedded UCHII regions. In addition, they will also make it possible to perform the first accurate modeling and characterization of the properties of dust in the source, thus to identify the carrier of the AME. Finally, the Herschel observations will have a legacy value, since, by providing the first FIR images of RCW 49, they will allow the unprecedented accurate estimate of its luminosity, mass, Star Formation Rate, as well as the possible identification of triggering sites. |

| 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. |
