| Abstract: |
Very deep infrared surveys have been performed with ISOCAM, ISO mid infrared imager on selected fields down to a limiting sensitivity of 100 micro janskies at 7 and 15 microns. At these wavelengths, we probe the emission of aromatic bands in starbursting galaxies and the hot dust continuum of AGNs. I will show that these two wavelengths provide interesting diagnostics on the nature of the galaxies at intermediate redshifts (z=0.5 to 1.5). I will illustrate these with our results on the HDF, were various other surveys have been performed (spectroscopic, radio and X-ray). I will show that ISOCAM observations, when combine to these other sets of data, allow us to quantify the relative importance of AGNs and starbursts as sources of the extragalactic infrared background between 100 and 200 microns. |
