12 September 2012 Observing faint targets with MIDI at the VLTI: the MIDI AGN large programme experience
Author Affiliations +
The VLTI/MIDI AGN Large Programme comprises 14 AGNs for which torus properties are being determined. Observations and data reduction are finished and show resolved dust emission in almost all of the sources. Questions addressed with this programme range from unification to the physics of accreting galactic nuclei. In particular, the observations allow us to dissect the parsec-scale infrared emission and to determine the sizes and fluxes of the various components. These AGNs are among the faintest objects ever studied with MIDI and require the data reduction software to be adjusted.
