Measuring the Coronal Properties of IC4329A with NuSTAR
L. W. Brenneman, G. Madejski, F. Fuerst +16
We present an analysis of a ~160 ks NuSTAR observation of the nearby bright Seyfert galaxy IC4329A. The high-quality broadband spectrum enables us to separate the effects of distan…
Constraints on the Neutron Star and Inner Accretion Flow in Serpens X-1 Using NuSTAR
J. M. Miller, M. L. Parker, F. Fuerst +17
We report on an observation of the neutron star low-mass X-ray binary Serpens X-1, made with NuSTAR. The extraordinary sensitivity afforded by NuSTAR facilitated the detection of a…
An Extremely Luminous and Variable Ultraluminous X-ray Source in the Outskirts of Circinus Observed with NuSTAR
D. J. Walton, F. Fuerst, F. A. Harrison +16
Following a serendipitous detection with the NuSTAR observatory, we present a multi-epoch spectral and temporal analysis of an extreme ultraluminous X-ray source (ULX) located in t…
The smooth cyclotron line in Her X-1 as seen with NuSTAR
Felix Fuerst, Brian W. Grefenstette, Ruediger Staubert +17
Her X-1, one of the brightest and best studied X-ray binaries, shows a cyclotron resonant scattering feature (CRSF) near 37 keV. This makes it an ideal target for detailed study wi…
NuSTAR Spectroscopy of GRS 1915+105: Disk Reflection, Spin, and Connections to Jets
J. M. Miller, M. L. Parker, F. Fuerst +15
We report on the results of spectral fits made to a NuSTAR observation of the black hole GRS 1915+105 in a "plateau" state. This state is of special interest because it is similar…
Weak Hard X-ray Emission from Two Broad Absorption Line Quasars Observed with NuSTAR: Compton-thick Absorption or Intrinsic X-ray Weakness?
B. Luo, W. N. Brandt, D. M. Alexander +22
We present NuSTAR hard X-ray observations of two X-ray weak broad absorption line (BAL) quasars, PG 1004+130 (radio loud) and PG 1700+518 (radio quiet). Many BAL quasars appear X-r…
The Nuclear Spectroscopic Telescope Array (NuSTAR) Mission
Fiona A. Harrison, William W. Craig, Finn E. Christensen +77
The Nuclear Spectroscopic Telescope Array (NuSTAR) mission, launched on 13 June 2012, is the first focusing high-energy X-ray telescope in orbit. NuSTAR operates in the band from 3…
