X-ray Spectral and Variability Properties of Low-Mass AGN
R. M. Ludlam, E. M. Cackett, K. Gultekin +3
We study the X-ray properties of a sample of 14 optically-selected low-mass AGN whose masses lie within the range 1E5 -2E6 M(solar) with XMM-Newton. Only six of these low-mass AGN…
The ASTRO-H X-ray Astronomy Satellite
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +250
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions developed by the Institute of Space and Astronautical Science (ISAS), with a planne…
X-ray Properties of Hard X-ray Selected AGN
Andrew C. Liebmann, Andrew C. Fabian, Sachiko Tsuruta
Using the latest 70 month Swift-BAT catalog we examined hard X-ray selected Seyfert I galaxies which are relatively little known and little studied, and yet potentially promising t…
Revealing the X-ray Variability of AGN with Principal Component Analysis
M. L. Parker, A. C. Fabian, G. Matt +7
We analyse a sample of 26 active galactic nuclei with deep XMM-Newton observations, using principal component analysis (PCA) to find model independent spectra of the different vari…
Discovery of O VII line emitting gas in elliptical galaxies
Ciro Pinto, Andrew C. Fabian, Norbert Werner +7
In the cores of ellipticals, clusters, and groups of galaxies, the gas has a cooling time shorter than 1 Gyr. It is possible to probe cooling flows through the detection of Fe XVII…
New Constraints on the Black Hole Low/Hard State Inner Accretion Flow with NuSTAR
J. M. Miller, J. A. Tomsick, M. Bachetti +12
We report on an observation of the Galactic black hole candidate GRS 1739-278 during its 2014 outburst, obtained with NuSTAR. The source was captured at the peak of a rising "low/h…
