Variable blurred reflection in the narrow-line Seyfert 1 galaxy Mrk 493
K. Bonson, L. C. Gallo, D. R. Wilkins +1
We examine a 200 ks XMM-Newton observation of the narrow-line Seyfert 1 galaxy Mrk 493. The active galaxy was half as bright as in a previous 2003 snapshot observation and the curr…
How well can we measure supermassive black hole spin?
K. Bonson, L. C. Gallo
Being one of only two fundamental properties black holes possess, the spin of supermassive black holes (SMBHs) is of great interest for understanding accretion processes and galaxy…
Flaring from the supermassive black hole in Mrk 335 studied with Swift and NuSTAR
D. R. Wilkins, L. C. Gallo, D. Grupe +3
Monitoring of the narrow line Seyfert 1 galaxy Markarian 335 (Mrk 335) with the Swift satellite discovered an X-ray flare beginning 2014 August 29. At the peak, the 0.5-5keV count…
Is HE 0436-4717 Anemic? A deep look at a bare Seyfert 1 galaxy
K. Bonson, L. C. Gallo, R. Vasudevan
A multi-epoch, multi-instrument analysis of the Seyfert 1 galaxy HE 0436-4717 is conducted using optical to X-ray data from XMM-Newton and Swift (including the BAT). Fitting of the…
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 blurred reflection interpretation for the intermediate flux state in Mrk 335
L. C. Gallo, A. C. Fabian, D. Grupe +7
As part of a long term monitoring campaign of Mrk 335, deep XMM-Newton observations catch the narrow-line Seyfert 1 galaxy (NLS1) in a complex, intermediate flux interval as the ac…
