Description ======================================================================== ==> this proposal requests an upgrade from priority 3 for jpuget.puget_1 ======================================================================== we propose to do a spectral exploration of the cold interstellar matter in the wavelength range accessible to iso. the excellent sensitivity of iso makes it unique to detect spectral features in low brightness extended sources. spectra of the integrated galactic emission will be obtained on lines of sight with high column density of interstellar gas avoiding regions of massive star formation. the large column density, combined with long integration times, will provide a high signal to noise on the continuum and allow the detection of weak dust features, vibration modes of individual pahs molecules, molecular emission from hot spots in hi clouds possibly heated by intermittent dissipation of turbulence, vibrational transitions of molecules seen in absorption against the diffuse emission of pahs and very small grains, and the associated emission. this proposal is a follow up of the proposal puget_1 which was partially supported in the first call. the time allocated in priority 2 allowed only the sws spectrum to be done on one line of sight. the lws grating observations are covered in the galactic line of sight central program. the first results from these observations confirm the existence of high excitation lines in this cold medium. we request an upgrade of the priority 3 time for the second line of sight and sws and lws fabry-perot observations.

Mission Description The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
