Description The Spectrum of IRAS 08339+6517 and its Physical Implications IRAS 08339+6517 is a highly compact starburst galaxy, whose remarkable nature was first recognized at optical wavelengths by Margon et al., in 1988 [1]. They noted its strong, narrow emission lines in H alpha , H x08eta , [OIII], [OII], [OI], [NII], [SII] and [CIV], and found it position to coincide with that of a previously-unidentified IRAS source, whose flux at 60 and 100 mu m, respectively was 5.9 and 6.5 Jy. The X-ray luminosity of the source is sim 1.0\times 10^{41} erg s ^{-1} , suggesting that it may be a hybrid AGN -starburst. Currently no far-infrared spectrum of this highly interesting nearby source exists, presumably because prior to Herschel no telescope was sufficiently powerful to provide a spectrum. The aim of this proposal is two-fold: (i) to obtain an analysis of the physical conditions --- temperature and density --- in the atomic and ionic and molecular constituents of this galaxy.s gaseous phases; the abundance of their primary elements O, C, and N; while also probing the far-infrared dust continuum and dust contents of the galaxy at longer wavelengths than IRAS provided; and (ii) to forge, as further explained, an intermediate chemical and thermodynamic link between galaxies in the nearby and distant universe.

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.
