The Soft-Excess in Mrk 509: Warm Corona or Relativistic Reflection?
Javier A. Garcia, Erin Kara, Dominic Walton +15
We present the analysis of the first NuSTAR observations ( ks), simultaneous with the last SUZAKU observations ( ks), of the active galactic nucleus of the brigh…
A Relativistic Disc Reflection Model for 1H0419-577: Multi-Epoch Spectral Analysis with XMM-Newton and NuSTAR
Jiachen Jiang, Dominic J. Walton, Andrew C. Fabian +1
We present a detailed analysis of the spectral properties of the Seyfert 1 galaxy 1H0419-577, based on the archival XMM-Newton, NuSTAR and simultaneous Swift observations taken bet…
HST/COS observations of the newly discovered obscuring outflow in NGC 3783
G. A. Kriss, M. Mehdipour, J. S. Kaastra +24
To understand the nature of transient obscuring outflows in active galactic nuclei, we observed the Seyfert 1 galaxy NGC 3783 on two occasions in December 2016 triggered by Swift m…
On the Nature of the X-ray Emission from the Ultraluminous X-ray Source, M33 X-8: New Constraints from NuSTAR and XMM-Newton
Lacey A. West, Bret D. Lehmer, Daniel Wik +12
We present nearly simultaneous NuSTAR and XMM-Newton observations of the nearby (832 kpc) ultraluminous X-ray source (ULX) M33 X-8. M33 X-8 has a 0.3-10 keV luminosity of LX ~ 1.4…
Multiple cyclotron line-forming regions in GX 301-2
F. Fuerst, S. Falkner, D. Marcu-Cheatham +6
We present two observations of the high-mass X-ray binary GX 301-2 with NuSTAR, taken at different orbital phases and different luminosities. We find that the continuum is well des…
The Ultra-Fast Outflow of WKK 4438: Suzaku and NuSTAR X-ray Spectral Analysis
Jiachen Jiang, Dominic J. Walton, Michael L. Parker +1
Previous X-ray spectral analysis has revealed an increasing number of AGNs with high accretion rates where an outflow with a mildly relativistic velocity originates from the inner…
