The evolution of type 1 AGN at 15um from the ELAIS
Abstract
We present the first preliminary estimate of the evolution of type 1 AGNs at 15 um. A new sample of sources selected from the ELAIS-S1 survey has been used together with the RMS sample. The ELAIS-S1 survey covers an effective area of 2.2 deg2 (total: 4 deg2) down to 1.2 mJy at 15 um. Spectroscopic identifications have been carried out in the range 17.2<R<20.0 at the 3.6m/ESO, NTT/ESO and 2dF/AAT. The luminosity function is steeper at bright luminosities in comparison to the previous estimates of Rush, Malkan & Spinoglio (1993). The evolution is compatible with a Pure Luminosity Evolution model with L(z)=L(0)(1+z)3.4.
