NuSTAR Hard X-ray Survey of the Galactic Center Region I: Hard X-ray Morphology and Spectroscopy of the Diffuse Emission
Kaya Mori, Charles J. Hailey, Roman Krivonos +35
We present the first sub-arcminute images of the Galactic Center above 10 keV, obtained with NuSTAR. NuSTAR resolves the hard X-ray source IGR J17456-2901 into non-thermal X-ray fi…
Hard X-ray Morphological and Spectral Studies of The Galactic Center Molecular Cloud Sgr B2: Constraining Past Sgr A* Flaring Activity
Shuo Zhang, Charles J. Hailey, Kaya Mori +15
Galactic Center (GC) molecular cloud Sgr B2 is the best manifestation of an X-ray reflection nebula (XRN) reprocessing a past giant outburst from the supermassive black hole Sgr A*…
Broadband X-ray Imaging and Spectroscopy of the Crab Nebula and Pulsar with NuSTAR
Kristin K. Madsen, Stephen Reynolds, Fiona Harrison +12
We present broadband (3 -- 78 keV) NuSTAR X-ray imaging and spectroscopy of the Crab nebula and pulsar. We show that while the phase-averaged and spatially integrated nebula + puls…
Locating the most energetic electrons in Cassiopeia A
Brian W. Grefenstette, Stephen P. Reynolds, Fiona A. Harrison +17
We present deep (2.4 Ms) observations of the Cassiopeia A supernova remnant with {\it NuSTAR}, which operates in the 3--79 keV bandpass and is the first instrument capable of sp…
