| Abstract: |
In the course of building ``unified models'' of Active Galactic Nuclei, the near infrared emission in the central kilo-parsec nuclear region is a key parameter: this wavelength range corresponds to the hot to warm dust emission, which originates in the torus and the Narrow Line Region (from a few parsecs to hundreds of parsecs). The measured flux is interpreted in terms of thermal emission and, via a dust modelisation, torus models are built. Using ISAAC at VLT, we observed a sample of AGNs in order to estimate the relative contribution between the thermal continuum emission from silicate & graphite dust grains and PAH molecules. |
