Abstract (from CDS):

We present results of our 7µm deep survey program made with ISOCAM, the infrared camera of ISO (Infrared Space Observatory). We have found 15 sources above a 5σrms significance in a small selected area (3'x3') in the Lockman HI hole. Among the 15 sources, 14 objects have also been observed in the near infrared (NIR: ∼2µm). The majority of the 7µm sources (11 objects) have NIR counterparts most of which are considered to be galaxies with intermediate redshifts. It is, however, intriguing that two 7µm sources have no NIR counterpart. These objects may be heavily reddened populations which have not been detected by existing optical and NIR deep surveys.
