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…
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…
First Results from NuSTAR Observations of Mkn 421
M. Baloković, M. Ajello, R. D. Blandford +34
Mkn 421 is a nearby active galactic nucleus dominated at all wavelengths by a very broad non-thermal continuum thought to arise from a relativistic jet seen at a small angle to the…
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…
SN 2010jl: Optical to hard X-ray observations reveal an explosion embedded in a ten solar mass cocoon
E. O. Ofek, A. Zoglauer, S. E. Boggs +24
(Abridged) Some supernovae (SNe) may be powered by the interaction of the SN ejecta with a large amount of circumstellar matter (CSM). Here we outline a method to measure the mass…
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…
