Description In our deep, "blind" wide-band millimeter spectroscopic follow-up campaign on HerMES Herschel-SPIRE sources, we have recently made a spectacular discovery. Based on the secure identification of a suite of atomic fine structure and molecular lines, we have discovered Herschel.s "first-born" starburst, a submillimeter galaxy at an unprecedented redshift of z=6.34, when the Universe was only 885 million years old. This source, dubbed FLS3, has a 250um to 20cm spectral energy distribution (SED) comparable to lower redshift starbursts (in the rest frame). However, due to its extreme redshift, the blue wing of the SED below 250um (rest-frame 34um) is only poorly constrained. This prevents investigations of the potential presence of warm, >100K dust associated with a dust-enshrouded, optically faint active galactic nucleus (AGN), for which there may be tentative evidence in the extensive, panchromatic dataset we were able to assemble on this source over the past three months. PACS photometry is perfectly suited to remedy this unfortunate gap in our wavelength coverage, as it covers the rest-frame 8-29um range - ideal to investigate the presence of warm dust associated with an obscured AGN. The proposed, inexpensive study (only 3.9hr of PACS photometry) will offer us a first glimpse into the science that SPICA will enable in the very early Universe at the end of this decade.

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.
