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…
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…
The broad band spectral variability of MCG-6-30-15 observed by NuSTAR and XMM-Newton
A. Marinucci, G. Matt, G. Miniutti +19
MCG-6-30-15, at a distance of 37 Mpc (z=0.008), is the archetypical Seyfert 1 galaxy showing very broad Fe K emission. We present results from a joint NuSTAR and XMM-Newton obse…
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…
The soft X-ray emission of Ark 120. XMM-Newton, NuSTAR, and the importance of taking the broad view
G. Matt, A. Marinucci, M. Guainazzi +17
We present simultaneous XMM-Newton and NuSTAR observations of the `bare' Seyfert 1 galaxy, Ark 120, a system in which ionized absorption is absent. The NuSTAR hard X-ray spectral c…
