===================================================================== ==> in this proposal, more time is being requested for fmirabel.camactiv ===================================================================== the ongoing analysis of isocam data from fmirabel.camactiv on active and starburst galaxies reveals that the spectral distribution of the energy in the mid-ir can come from different origins (pahs, gaseous emission, continuum from dust), the contribution of each origin being variable from an object to an other. to identify the origin of the emission, avoiding confusion, we need a more precise spectral information than the one provided by the broad-band filters lw2(5-8.5 microns) and lw3(12-18 microns). moreover, an other result of the analysis is that the spatial information remains crucial because these emissions can come either from double nuclei or from extended emission from starburst or both. we intend to complete and slightly expand with few objects more the study undertaken with the fmirabel.camactiv proposal of the isocam consortium.s guaranteed time. for the brightest objects of our sample, we propose to perform observations with the spectral observing mode of isocam. for fainter objects we propose to complete our previous observations in broad band filters with a carefully selected narrow band filter in order to clarify the physical origin of the detected emission. experience obtained with the camactiv observations will be used with benefice to improve the quality of the new observations by correction of integration times and observing strategy.

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.
