Description We have discovered a z=6.1 Submillimetre Galaxy from a detailed survey of 0.5 sq deg in GOODS-N, FLS, and LockmanEast. HDF259 was originally detected by SCUBA and the VLA, but recently constrained through Herschel-SPIRE detections. The redshift is confirmed through a Keck spectroscopic redshift, an optical-near-mid-IR photo-z (as an I-band dropout with a rising stellar bump at 1.6um), and through template fitting with a most likely T_dust in the SPIRE through 1.2mm wavelengths. Even if the optical data incorrect redshift, an extreme range of T_dust secures the redshift as lying from z=4-8. This SMG represents the first opportunity yet to study the rest-frame 7.7um region PAH features in a z>6 star forming galaxy, using the PACS spectrometer (where the 7.7um strong PAH feature comes into the PACS 51-70um and 70-105um bands only at z>5.9). The strength of the PAH, estimated both from extrapolated flux measurements from Spitzer-MIPS, and from the z~2 L_IR-L_PAH relation (Pope et al. 2008) ensures that a typical PAH in this SMG will be well detected in 4.8hrs total programme duration.

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.
