Dust in the Central Parsecs of AGNs

Almudena Prie

I will discuss the new challenges that parsec-scale observations in the IR, when combined with comparable physical scales in radio, millimetre, optical, UV, and X-ray of the nearest AGN, are posing to us regarding the nature of the nuclear emission, the ubiquitous presence of nuclear dust filaments, and the role of these filaments as accretion drivers. The way these observations challenge the requirement of a torus and question one of its fundamental attributes, which is the collimation of the nuclear radiation, will be discussed.

An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.
