    ISOCAM cosmological Surveys (1999)

    Notes: Abstract Several deep surveys have been performed at 7 and 15 μm by using the mid-infrared camera ISOCAM on board the ISO satellite. We review their first results, emphasizing on the excess detected in the 15 μm counts with respect to the predictions of models with a mild evolution that is sufficient to explain the IRAS counts. We point out that a large fraction of the past star formation history is missed when studied using UV/visible data only.

    Bremsstrahlung gamma radiation and interstellar electron spectrum in the local interstellar medium (1978)
    Springer
    Astrophysics and space science 59 (1978), S. 73-83

    Notes: Abstract We present a detailed study of the bremsstrahlung gamma-ray emissivity of the galactic disk. We show that there are large uncertainties in the production spectrum of photons in the medium energy range (10–100 MeV) due to our lack of knowledge of the interstellar electron spectrum below a few hundred MeV. In fact, gamma-ray observations can be of great help in determining this spectrum. At present, the spectral shape of the local gamma-ray emissivity above 30 MeV is available, thanks to the SAS-II and the COS-B satellites. Comparing it to our calculations, we determine the local interstellar electron flux in the 50–500 MeV range; the corresponding integrated gamma-ray emissivity above 100 MeV is equal to 2.4×10−25 photons s−1 (H-atom)−1, 60% higher than previously accepted values.
