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.
