What shapes the Absorption Measure Distribution in AGN outflows
T. P. Adhikari, A. Różańska, K. Hryniewicz +2
The Absorption Measure Distribution (AMD) in the X-ray outflows of Seyfert active galactic nuclei (AGN) describes the distribution of absorbing column density as a function of ioni…

X-ray Structure between the Innermost Disk and Optical Broad Line Region in NGC 4151
J. M. Miller, E. Cackett, A. Zoghbi +9
We present an analysis of the narrow Fe K-alpha line in Chandra/HETGS observations of the Seyfert AGN, NGC 4151. The sensitivity and resolution afforded by the gratings reveal asym…

Recurring obscuration in NGC 3783
J. S. Kaastra, M. Mehdipour, E. Behar +14
Obscuration of the continuum emission from active galactic nuclei by streams of gas with relatively high velocity (> 1000 km/s) and column density (>3E25 per m2) has been seen in a…
