A low-flux state in IRAS 00521−7054 seen with NuSTAR and XMM–Newton: relativistic reflection and an ultrafast outflow

Walton, Dominic; Nardini, Emanuele; Gallo, Luigi C.; Reynolds, M. T.; Ricci, C.; Dauser, Thomas; Fabian, Andrew C.; Garcia, J. A.; Harrison, F. A.; Risaliti, G.; Stern, D. (Oxford University PressRoyal Astronomical Society, 2019-01-16)

We present results from a deep, coordinated XMM–Newton + NuSTAR observation of the Seyfert 2 galaxy IRAS 00521−7054. The NuSTAR data provide the first detection of this source in ...
The nuclear environment of the NLS1 Mrk 335: Obscuration of the X-ray line emission by a variable outflow

Parker, M. L.; Longinotti, A. L.; Schartel, N.; Grupe, D.; Komossa, S.; Kriss, G.; Fabian, Andrew C.; Gallo, Luigi C.; Harrison, F. A.; Jiang, J.; Kara, E.; Krongold, Y.; Matzeu, G. A.; Pinto, C.; Santos-Lleo, M. (Royal Astronomical SocietyOxford University Press, 2019-09-12)

We present XMM–Newton, NuSTAR, Swift, and Hubble Space Telescope observations of the Narrow-line Seyfert 1 galaxy Mrk 335 in a protracted low state in 2018 and 2019. The X-ray flux ...
The NuSTAR spectrum of Mrk 335: extreme relativistic effects within two gravitational radii of the event horizon

Parker, M. L.; Wilkins, D. R.; Fabian, A. C.; Grupe, D.; Dauser, T.; Matt, G.; Harrison, F. A.; Brenneman, L.; Boggs, S. E.; Christensen, F. E.; Gallo, Luigi C. (Oxford University Press, 2014-09-11)

We present 3–50 keV NuSTAR observations of the active galactic nuclei Mrk 335 in a very low flux state. The spectrum is dominated by very strong features at the energies of the iron line at 5–7 keV and Compton ...
