| Description | We have discovered a z=6.1 Submillimetre Galaxy from a detailedsurvey of 0.5 sq deg in GOODS-N, FLS, and LockmanEast. HDF259 was originally detected by SCUBA and the VLA, but recentlyconstrained 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_dustin the SPIRE through 1.2mm wavelengths.Even if the optical data incorrect redshift, an extreme rangeof T_dust secures the redshift as lying from z=4-8.This SMG represents the first opportunity yet to study the rest-frame7.7um region PAH features in a z>6 star forming galaxy,using the PACS spectrometer (where the 7.7um strong PAH featurecomes 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_PAHrelation (Pope et al. 2008) ensures that a typical PAH in this SMGwill 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 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
