NuSTAR: Probing the Geometry of Obscuration in the High Energy X-ray Band
Abstract
NuSTAR is the first focusing telescope to operate in the high energy X-ray (3-79 keV). Using high quality measurements across a broad energy band NuSTAR probes the band where Compton reflection from dense material imprints distinctive features on the spectrum. Combined with timing information, this is providing measurements of the geometry and size scales of dense structures in the central regions of AGN. I will highlight results from the mission which have led to improved understanding of the structure of the torus, and the relation to unified models of AGN.
