Description The reionisation of the universe between redshifts 6 and 30 is the one fundamental astrophysical event since the Big Bang. The role of galaxies in this process is still not properly understood. Several star forming galaxies at z ~ 6 have been identified in recent deep, narrow field surveys, but the expensive observations along with cosmic variance and contamination make it difficult to assess their contribution to reionisation, or to significantly increase the sample. By virtue of being extremely luminous end states in the evolution of massive stars, gamma ray bursts (GRBs) are a critically important tracer of star formation out to the highest redshifts. It has now been demonstrated that GRBs exist at z>6, and there are already published HST and Spitzer observations of the host galaxy of GRB050904 at z=6.3. Spectroscopic confirmation, including detailed information on the host ISM, is available for this burst. Here we propose to observe the host galaxy of GRB 050904 with Herschel PACS and SPIRE to very deep limits. We aim to extend our knowledge of this galaxy to the far-infrared and submillimetre wavelengths. This will allow us to build realistic models, since those windows are unexplored to date, and to describe the physical properties of a high z GRB host galaxy, thus directly probing reionisation and the role high z galaxies in the process. Further we will test whether the M Z and L Z relations evolve beyond the current redshift limits.

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.
