An axisymmetric hydrodynamical model for the torus wind in AGN. II: X-ray excited funnel flow
A. Dorodnitsyn, T. Kallman, D. Proga
We have calculated a series of models of outflows from the obscuring torus in active galactic nuclei (AGN). Our modeling assumes that the inner face of a rotationally supported tor…
The Variable Warm Absorber in Circinus X-1
N. S. Schulz, T. E. Kallman, D. K. Galloway +1
We observed Circinus X-1 twice during a newly reached low-flux phase near zero orbital phase using the High-Energy Transmission Grating Spectrometer (HETGS) onboard Chandra. In bot…
Fe II Diagnostic Tools for Quasars
E. Verner, F. Bruhweiler, D. Verner +3
The enrichment of Fe, relative to alpha-elements such as O and Mg, represents a potential means to determine the age of quasars and probe the galaxy formation epoch. To explore how…
Chandra Grating Spectroscopy of the X-ray Binary 4U 1700-37 in a Flaring State
B. Boroson, S. Vrtilek, T. Kallman +1
Chandra X-ray Observatory grating spectra of the supergiant X-ray Binary 4U 1700-37 reveal emission lines from hydrogen and helium-like S, Si, Mg, and Ne in the 4-13 A range. The s…
