We request 9.9 hours of observing time to map M33 at 70 micron. This project will enable a spatially-resolved investigation of HII regions in this galaxy, with the goal of determining changes 1) in the respective amount of PAH, stochastic and equilibrium dust emissions, in order to 2) constrain the radiation field and the properties of dust emission as a function of the evolutionary phase of the HII regions and across the disk of the galaxy. We will resolve the internal structure and physical properties of the HII regions down to virgul24 pc (<6), and construct spatially-resolved, pixel-based, UV-to-FIR SEDs. This proposal is a key complement to the HerM33es key project which mainly focuses on the mapping of major FIR cooling lines, with only a small fraction of the time dedicated to imaging from 100 micron to 500 micron (PACS and SPIRE).

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.
