Absorption Measure Distribution of the Outflow in IRAS 13349+2438: Direct Observation of Thermal Instability?
Tomer Holczer, Ehud Behar, Shai Kaspi
We analyze the Chandra X-ray spectrum obtained with the HETGS grating spectrometer of IRAS 13349+2438, which has one of the richest absorption spectra of a quasar outflow. Absorpti…
The mass-energy budget of the ionised outflow in NGC 7469
A. J. Blustin, G. A. Kriss, T. Holczer +6
Although AGN feedback through ionised winds is of great importance in models of AGN/galaxy coevolution, the mass and energy output via these winds, even in the nearby universe, is…
Inner-shell Absorption Lines of Fe~VI-- Fe~XVI: A Many-body Perturbation Theory Approach
Ming F. Gu, Tomer Holczer, Ehud Behar +1
We provide improved atomic calculation of wavelengths, oscillator strengths, and autoionization rates relevant to the inner-shell transitions of Fe~VI--XVI, the so-called…
Is The Fe M-shell Absorber Part of The Outflow in Active Galactic Nuclei?
Tomer Holczer, Ehud Behar, Shai Kaspi
The X-ray emission of many active galactic nuclei (AGNs) is absorbed between 15 and 17 Angstrom by means of unresolved (inner-shell) transition arrays (UTAs) of Fe M-shell ions. Th…
