Description We propose observations in the two reddest PACS and all three SPIRE bands of the host galaxies of a sample of five GRBs. The sample was carefully selected based on the detection of large extinction in the GROND SED of the GRB afterglow, and all hosts have a large amount of multiwavelength data in hand, including sensitive submm observations. Together with the Herschel data, we will model the SEDs from the UV to the submm with the broadband galaxy SED fitting software, CIGALE, to derive bolometric luminosities and SFRs, and constrain dust mass and dust temperature. We will compare the dust properties of the whole galaxy with that derived from the GRB afterglow to constrain the dust clumpiness (covering fraction, total extinction). We will also compare the dust and stellar components of the galaxies, and investigate the GRB hosts in the context of other high-z galaxies. The Herschel data will provide indispensable observations of the peak of the thermal dust emission component, which accompanied with our APEX and SCUBA submm observations will provide the most accurate measurements to date of the extinction and emission properties of dust within GRB host galaxies.

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.
