A Long Look at NGC 3783 with Chandra/HETG and NuSTAR
Abstract
We have obtained a simultaneous observation of the Seyfert 1 AGN NGC 3783 with Chandra/HETG (160 ks) and NuSTAR (80 ks). The primary purpose of this deep observing campaign is to address the highly disparate measurements of supermassive black hole spin in this source reported in the literature. The high signal-to-noise, broadband X-ray spectra enabled by a simultaneous Chandra and NuSTAR pointing allow us to definitively deconvolve the primary continuum, absorption and reprocessed emission components in NGC 3783 for the first time. We then isolate the signatures of relativistic reflection from the inner disk and measure the spin of the black hole with previously unachievable accuracy. Here we report on our spectral modeling results and also discuss the implications of this work for our understanding of the physics at work in the corona, the nature of the soft X-ray excess, and the structure of the absorbing gas at present in this bright, nearby AGN.
