NuSTAR and XMM-Newton Observations of the Hard X-Ray Spectrum of Centaurus A
F. Fuerst, C. Mueller, K. K. Madsen +28
We present simultaneous XMM-Newton and NuSTAR observations spanning 3-78 keV of the nearest radio galaxy, Centaurus A (Cen A). The accretion geometry around the central engine in C…
The Transient Accereting X-Ray Pulsar XTE J1946+274: Stability of the X-Ray Properties at Low Flux and Updated Orbital Solution
Diana M. Marcu-Cheatham, Katja Pottschmidt, Matthias Kühnel +19
We present a timing and spectral analysis of the X-ray pulsar XTE J1946+274 observed with Suzaku during an outburst decline in 2010 October and compare with previous results. XTE J…
A Soft X-Ray Spectral Episode for the Clocked Burster, GS 1826-24 as Measured by Swift and NuSTAR
J. Chenevez, D. K. Galloway, J. J. M. in 't Zand +12
We report on NuSTAR and Swift observations of a soft state of the neutron star low-mass X-ray binary GS 1826-24, commonly known as the "clocked" burster. The transition to the soft…
Optical and Near-Infrared Spectroscopy of the Black Hole Swift J1753.5-0127
Farid Rahoui, John A. Tomsick, Mickael Coriat +7
We report on a multiwavelength observational campaign of the black hole X-ray binary Swift J1753.5-0127 that consists of an ESO/X-shooter spectrum supported by contemporaneous Swif…
Phase resolved spectroscopy and Kepler photometry of the ultracompact AM CVn binary SDSS J190817.07+394036.4
T. Kupfer, P. J. Groot, S. Bloemen +8
{\it Kepler} satellite photometry and phase-resolved spectroscopy of the ultracompact AM CVn type binary SDSS J190817.07+394036.4 are presented. The average spectra reveal a variet…
The Accreting Black Hole Swift J1753.5-0127 from Radio to Hard X-Ray
John A. Tomsick, Farid Rahoui, Mari Kolehmainen +19
(abridged) We report on multi-wavelength measurements of Swift J1753.5-0127 in the hard state at L=2.7e36 erg/s (assuming d=3 kpc) in 2014. The radio emission is optically thick sy…
3C 273 with NuSTAR: Unveiling the AGN
Kristin K. Madsen, Felix Fürst, Dominic J. Walton +17
We present results from a 244\,ks \textit{NuSTAR} observation of 3C\,273 obtained during a cross-calibration campaign with the \textit{Chandra}, \textit{INTEGRAL}, \textit{Suzaku},…
NuSTAR and Swift observations of the black hole candidate XTE J1908+094 during its 2013 outburst
Lian Tao, John A. Tomsick, Dominic J. Walton +15
The black hole candidate XTE J1908+094 went into outburst for the first time since 2003 in October 2013. We report on an observation with the Nuclear Spectroscopic Telescope Array…
The Multi-Layer Variable Absorbers in NGC 1365 Revealed by XMM-Newton and NuSTAR
E. Rivers, G. Risaliti, D. J. Walton +15
Between July 2012 and February 2013, NuSTAR and XMM-Newton performed four long-look joint obser- vations of the type 1.8 Seyfert, NGC 1365. We have analyzed the variable absorption…
Simultaneous NuSTAR/Chandra observations of the Bursting Pulsar GRO J1744-28 during its third reactivation
G. Younes, C. Kouveliotou, B. W. Grefenstette +21
We report on a 10 ks simultaneous Chandra/HETG-NuSTAR observation of the Bursting Pulsar, GRO J1744-28, during its third detected outburst since discovery and after nearly 18 years…
