Coronal Properties of the Seyfert 1.9 Galaxy MCG -05-23-016 Determined from Hard X-ray Spectroscopy with NuSTAR
M. Baloković, G. Matt, F. A. Harrison +15
Measurements of the high-energy cut-off in the coronal continuum of active galactic nuclei have long been elusive for all but a small number of the brightest examples. We present a…
NuSTAR Spectroscopy of Multi-Component X-ray Reflection from NGC 1068
Franz E. Bauer, Patricia Arevalo, Dominic J. Walton +26
We report on observations of NGC1068 with NuSTAR, which provide the best constraints to date on its ~keV spectral shape. We find no strong variability over the past two decade…
A NuSTAR observation of the center of the Coma Cluster
F. Gastaldello, D. R. Wik, S. Molendi +13
We present the results of a 55ks NuSTAR observation of the core of the Coma Cluster. The global spectrum can be explained by thermal gas emission, with a conservative 90% upper lim…
No Time for Dead Time: Timing analysis of bright black hole binaries with NuSTAR
Matteo Bachetti, Fiona A. Harrison, Rick Cook +20
Timing of high-count rate sources with the NuSTAR Small Explorer Mission requires specialized analysis techniques. NuSTAR was primarily designed for spectroscopic observations of s…
The NuSTAR View of Nearby Compton-thick AGN: The Cases of NGC 424, NGC 1320 and IC 2560
M. Baloković, A. Comastri, F. A. Harrison +25
We present X-ray spectral analyses for three Seyfert 2 active galactic nuclei, NGC 424, NGC 1320, and IC 2560, observed by NuSTAR in the 3-79 keV band. The high quality hard X-ray…
Weak Hard X-ray Emission from Broad Absorption Line Quasars: Evidence for Intrinsic X-ray Weakness
B. Luo, W. N. Brandt, D. M. Alexander +19
We report NuSTAR observations of a sample of six X-ray weak broad absorption line (BAL) quasars. These targets, at z=0.148-1.223, are among the optically brightest and most luminou…
NuSTAR unveils a Compton-thick Type 2 quasar in Mrk 34
P. Gandhi, G. B. Lansbury, D. M. Alexander +27
We present Nustar 3-40 keV observations of the optically selected Type 2 quasar (QSO2) SDSS J1034+6001 or Mrk 34. The high-quality hard X-ray spectrum and archival XMM-Newton data…
Observations of MCG-5-23-16 with Suzaku, XMM-Newton and NuSTAR: Disk tomography and Compton hump reverberation
A. Zoghbi, E. M. Cackett, C. Reynolds +12
MCG-5-23-16 is one of the first AGN where relativistic reverberation in the iron K line originating in the vicinity of the supermassive black hole was found, based on a short XMM-N…
NuSTAR and XMM-Newton Observations of NGC 1365: Extreme Absorption Variability and a Constant Inner Accretion Disk
D. J. Walton, G. Risaliti, F. A. Harrison +24
We present a spectral analysis of four coordinated NuSTAR+XMM-Newton observations of the Seyfert galaxy NGC 1365. These exhibit an extreme level of spectral variability, which is p…
Simultaneous NuSTAR and XMM-Newton 0.5-80 keV spectroscopy of the Narrow Line Seyfert 1 galaxy SWIFT J2127.4+5654
A. Marinucci, G. Matt, E. Kara +20
We present a broad band spectral analysis of the joint XMM-Newton and NuSTAR observational campaign of the Narrow Line Seyfert 1 SWIFT J2127.4+5654, consisting of 300 ks performed…
{\it NuSTAR} Reveals an Intrinsically X-ray Weak Broad Absorption Line Quasar in the Ultraluminous Infrared Galaxy Markarian 231
Stacy H. Teng, W. N. Brandt, F. A. Harrison +24
We present high-energy (3--30 keV) {\it NuSTAR} observations of the nearest quasar, the ultraluminous infrared galaxy (ULIRG) Markarian 231 (Mrk 231), supplemented with new and sim…
