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…
Suzaku observations of Mrk 335: Confronting partial covering and relativistic reflection
L. C. Gallo, D. R. Wilkins, K. Bonson +7
We report on the deepest X-ray observation of the narrow-line Seyfert 1 galaxy Mrk 335 in the low-flux state obtained with Suzaku. The data are compared to a 2006 high-flux Suzaku…
A Partial Eclipse of the Heart: The Absorbed X-ray Low State in Mrk 1048
M. L. Parker, N. Schartel, S. Komossa +3
We present two new XMM-Newton observations of an unprecedented low flux state in the Seyfert 1 Mrk 1048 (NGC 985), taken in 2013. The X-ray flux below 1 keV drops by a factor of 4-…
Black hole spin and size of the X-ray emitting region(s) in the Seyfert 1.5 galaxy ESO 362-G18
Beatriz Agís-González, Giovanni Miniutti, Erin Kara +7
We report results from multi-epoch X-ray observations of the Seyfert 1.5 galaxy ESO 362-G18 performed between November 2005 and June 2010. ESO 362-G18 generally exhibits the typica…
PCA of PCA: Principal Component Analysis of Partial Covering Absorption in NGC 1365
M. L. Parker, D. J. Walton, A. C. Fabian +1
We analyse 400 ks of XMM-Newton data on the active galactic nucleus NGC 1365 using principal component analysis (PCA) to identify model independent spectral components. We find two…
X-ray reflection in oxygen-rich accretion discs of ultra-compact X-ray binaries
O. K. Madej, J. Garcia, P. G. Jonker +4
We present spectroscopic X-ray data of two candidate ultra-compact X-ray binaries: 4U~0614+091 and 4U~1543624. We confirm the presence of a broad O VIII Ly reflection line (a…
