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…
The High-Velocity Outflow of PG 1211+143: An Unbiased View Based on Several Observations
Shai Kaspi, Ehud Behar
We present and discuss high-resolution grating spectra of the quasar PG1211+143 obtained over three years. Based on an early observation from 2001, we find an outflow component of…
Principal component analysis of the X-ray variability in NGC 7469
A. J. Blustin, S. V. Fuerst, G. Branduardi-Raymont +3
We apply Principal Component Analysis (PCA) to study the variability of the X-ray continuum in the Seyfert 1 galaxy NGC 7469. The PCA technique is used to separate out linear compo…
The High-Velocity Outflow of PG1211+143 May Not be That Fast
Shai Kaspi, Ehud Behar
We analyze the X-ray spectrum of the quasar PG1211+143 observed with the CCD and grating spectrometers on board XMM-Newton. Using an ion by ion fitting model we find an outflow com…
Accretion onto the Companion of Eta Carinae During the Spectroscopic Event: II. X-Ray Emission Cycle
Muhammad Akashi, Noam Soker, Ehud Behar
We calculate the X-ray luminosity and light curve for the stellar binary system Eta Carinae for the entire orbital period of 5.54 years. By using a new approach we find, as suggest…
X-Ray Emission by A Shocked Fast Wind from the Central Stars of Planetary Nebulae
Muhammad Akashi, Noam Soker, Ehud Behar
We calculate the X-ray emission from the shocked fast wind blown by the central stars of planetary nebulae (PNs) and compare with observations. Using spherically symmetric self sim…
