Title Constraining the TP-AGB Contribution to Integrated Stellar Populations With FIR Dust Temperatures

Author atlee, d.
Description We propose PACS 70um and 160um photometry of 5 post-starbust galaxies selected from the SDSS and detected in the Spitzer MIPS 24um channel. We will measure the temperature of the FIR dust continuum and determine the contribution of enshrouded star formation to the observed 24um luminosity. This measurement, in combination with optical and NIR spectroscopy will allow us to constrain the bolometric contribution of TP-AGB stars to these galaxies. By doing so, we will constrain the TP-AGB as a systematic bias for MIR measurements of star formation and AGN and determine the extent to which TP-AGB stars must be taken into account when inferring stellar masses from observed luminosities and colors of galaxies. The observations will consume 9 hours of spacecraft time for these 5 objects, and we will leverage this time by employing photometry from the Herschel archive for one additional source and considering the impact of 7 other post-starburst galaxies with MIPS upper limits. This gives us a total sample of 13 galaxies to determine the importance of the TP-AGB as a function of burst age and strength and to extrapolate from our sample to a more extensive range in star formation histories.

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 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
