| Description | The Spectrum of IRAS 08339+6517 and its Physical ImplicationsIRAS 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 and6.5 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 galaxys 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 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
