Abstract

Usining mid-IR high angular resolution (0.3 arcsec) data from CanariCam on the 10.4m Gran Telescopio CANARIAS we study the mid-IR nuclear emission of a nearby (z<0.1) sample of QSOs. The QSOs are selected with N-band flux (fN>0.02 Jy) and hard X-ray flux (fX(2-10 keV)>1043 erg s-1). From the analysis of this data we find that the mid-IR emission is unresolved at scales of a few hundred of pc. We use unresolved emission at H-band (e.g., Veilleux et al. 2009b) and the IRS-Spitzer spectrum (e.g., Schweitzer et al. 2006) to build near- to mid-IR unresolved spectral energy distribution (SEDs).
