  • HIFI stability as measured during ILT phase
  • 2008
  • Ingår i: 19th International Symposium on Space Terahertz Technology, ISSTT 2008; Groningen; Netherlands; 28 April 2008 through 30 April 2008. ; , s. 92-102
  • Konferensbidrag (refereegranskat)abstract
    • We present here the stability results of the high frequency heterodyne instrument (HIFI), to be flown on the Herschel space observatory. The measurements were taken as part of the instrument level tests (ILT) in the spring of 2007. Herschel is ESA's fourth cornerstone mission in the Horizon 2000+ program, and aims at observations in the Far-InfraRed and sub-millimeter wavelength region. HIFI itself is one of three instruments onboard Herschel. The other two being PACS, the photodetector array camera and spectrometer, and SPIRE, the spectral and photometric imaging receiver.

  • A photon dominated region code comparison study
  • 2007
  • Ingår i: Astronomy and Astrophysics. - : EDP Sciences. - 0004-6361 .- 1432-0746. ; 467:No. 1 (May III 2007), s. 187-206
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims.We present a comparison between independent computer codes, modeling the physics and chemistry of interstellar photon dominated regions (PDRs). Our goal was to understand the mutual differences in the PDR codes and their effects on the physical and chemical structure of the model clouds, and to converge the output of different codes to a common solution.Methods. A number of benchmark models have been created, covering low and high gas densities n = 103,105.5 cm-3 and far ultraviolet intensities $\chi$ = 10, 105 in units of the Draine field (FUV: 6
