Description The Spectrum of IRAS 08339+6517 and its Physical

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 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
