2010/11/16
Narrow-line Seyfert 1 galaxies (NLS1s) with very small broad-line widths (say,FWHM(H ) . 1200 kms-1) represent the extreme type of Seyfert 1 galaxies that have small black hole masses (MBH) and/or hig...

Context. Extragalactic nuclear activity is best explored with observations at high energies, where the most extreme flux and spectral variations are expected to occur, witnessing changes in the accret...
The X-ray Power Spectral Density Function of the Seyfert Active Galactic Nucleus NGC 7469
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/5
We present the broadband X-ray power spectral density function (PSD) of the X-ray-luminous Seyfert 1.2 NGC 7469, measured from Rossi X-ray Timing Explorer monitoring data and two XMM-Newton observatio...
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 ...
