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…
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…
Discovery of a ~2 hr high frequency X-ray QPO and iron K alpha reverberation in the active galaxy MS 2254.9-3712
W. N. Alston, M. L. Parker, J. Markeviciute +5
We report the discovery of a Hz ( hr) X-ray quasi-periodic oscillation (QPO) in the active galaxy MS 2254.9-3712, using a ks XMM-Newton…
Iron K and Compton hump reverberation in SWIFT J2127.4+5654 and NGC 1365 revealed by NuSTAR and XMM-Newton
E. Kara, A. Zoghbi, A. Marinucci +13
In the past five years, a flurry of X-ray reverberation lag measurements of accreting supermassive black holes have been made using the XMM-Newton telescope in the 0.3-10 keV energ…
No Time for Dead Time: Timing analysis of bright black hole binaries with NuSTAR
Matteo Bachetti, Fiona A. Harrison, Rick Cook +20
Timing of high-count rate sources with the NuSTAR Small Explorer Mission requires specialized analysis techniques. NuSTAR was primarily designed for spectroscopic observations of s…
The changing X-ray time lag in MCG-6-30-15
E. Kara, A. C. Fabian, A. Marinucci +6
MCG-6-30-15 is one of the most observed Narrow Line Seyfert 1 galaxies in the X-ray band. In this paper we examine the X-ray time lags in this source using a total of 600 ks in obs…
