Nuclear activity in nearby galaxies

Abstract

Aims. Dust enshrouded activity can be studied ideally by mid-infrared (MIR) observations. To explore the active galactic nuclei (AGN) versus star forming origin of the nuclear MIR emission of galaxies, observations of high spatial resolution are required. We report on 11.3 μm observations with VISIR at the VLT, which reach spatial resolution (FWHM).
