Chandra High Energy Grating Observations of the Fe Ka Line Core in Type 2 Seyfert Galaxies: A Comparison with Type 1 Nuclei
galaxies active – line:profile – X-rays:galaxies
2011/8/24
We present a study of the core of the Fe Ka emission line at ~6.4 keV in a sample of type II Seyfert galaxies observed by the Chandra High Energy Grating (HEG). The sample consists of 29 observations ...

Context. Parallel analysis of the large-scale morphology and local environment of matched active and control galaxy samples plays an important role in studies of the fueling of active galactic nuclei.
A Multi-Wavelength Study of the Nature of Type 1.8/1.9 Seyfert Galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/4
We focus on determining the underlying physical cause of a Seyfert galaxy's appearance as type a 1.8 or 1.9. Are these "intermediate" Seyfert types typical Seyfert 1 nuclei with reddened broad-line re...
Iron line profiles in Suzaku spectra of bare Seyfert galaxies
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/28
We methodically model the broad-band Suzaku spectra of a small sample of six 'bare' Seyfert galaxies: Ark 120, Fairall 9, MCG-02-14-009, Mrk 335, NGC 7469 and SWIFT J2127.4+5654. The analysis of bare ...
