Connection between PAHs and small hydrocarbons in the Horsehead Nebula Photo-Dissociation Region
David Teyssier, David Fosse, Maryvonne Gerin +3
We present recent observations of small hydrocarbons (C3H2, C2H, C4H) with high abundances in the Photo-Dissociation Region of the Horsehead nebula. Our results show for the first…
The extragalactic background and its fluctuations in the far-infrared wavelengths
G. Lagache, J-L. Puget, A. Abergel +22
A Cosmic Far-InfraRed Background (CFIRB) has long been predicted that would traces the intial phases of galaxy formation. It has been first detected by Puget et al.(1996) using COB…
First detection of the WIM dust emission. Implication for the Cosmic Far-Infrared Background
G. Lagache, A. Abergel, F. Boulanger +2
We present a new analysis of the far-IR emission at high Galactic latitude based on COBE and HI data. A decomposition of the Far-IR emission over the HI, H^+ and H_2 Galactic gas c…
A classical approach to faint extragalactic source extraction from ISOCAM deep surveys. Application to the Hubble Deep Field
F. -X. Desert, J. -L. Puget, D. L. Clements +4
We have developed a general data reduction technique for ISOCAM data coming from various deep surveys of faint galaxies. In order to reach the fundamental limits of the camera (due…
