Description We propose to image M31 (3x1deg) with PACS and SPIRE in slow parallel mode
to understand the dust heating processes and efficiencies in normal spiral
galaxies. Our observations will provide a unique deep and panchromatic
70,100,160, 250, 350 and 500 micron view of the inner stellar disk of M31
at the highest possible spatial resolution with Herschel. Combined with
Spitzer 8 and 24 micron data, this imaging will provide a detailed map of
the thermal-IR SED at a resolution unparalleled for any other large galaxy.
The 6-18 arcsec spatial resolution of Herschel at 70-250 micron corresponds
to 20-60 pc at the distance of M31 and matches the scales of molecular
clouds complexes (GMCs; virgul 40 pc) as well as of HII regions and clusters thereof
(about 10-50 pc). Existing GALEX and optical data, as well as upcoming 900
orbit HST imaging will provide us with an unprecedented, resolved picture of
all stellar populations younger than virgul200 Myrs, which should encompass much
of the r^ant dust heating sources at scales of a few to a few 10 parsecs.

With such information on both the thermal state of the dust and on the
heating sources in hand, our SED modelling can then be used to understand
over what length scales and with what efficiency stars heat the dust. The
results will also serve as a local high resolution calibration of Herschel
data on more distant galaxies such as from the KINGFISH OT key project.
This proposal is part of a coordinated effort to image M31 and its
surroundings: Here we aim on sensitive 70-250 micron coverage at the
highest spatial resolution for the bright inner stellar disk while the
diffuse outer cold dust envelope including the companion NGC205 are the
target of a second proposal by Fritz et al. For the analysis of extended
very cold dust emission, the SPIRE data will be provided collaboratively
to the other team.

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.
