NuSTAR observations of the bullet cluster: constraints on inverse Compton emission
Daniel R. Wik,Daniel R. Wik,Allan Hornstrup,Silvano Molendi,Grzegorz Madejski,Fiona A. Harrison,Andreas Zoglauer,Brian W. Grefenstette,Fabio Gastaldello,Kristin K. Madsen,Niels Jørgen Stenfeldt Westergaard,Desiree Della Monica Ferreira,Takao Kitaguchi,Kristian Pedersen,Steven E. Boggs,Finn E. Christensen,William W. Craig,William W. Craig,Charles J. Hailey,Daniel Stern,William W. Zhang +20 more
TL;DR: In this article, a complete background model constructed of physically inspired components constrained by extragalactic survey field observations is presented, the specific parameters of which are derived locally from data in non-source regions of target observations.
Journal ArticleDOI

TL;DR: In this article, the results of NuSTAR and XMM-Newton observations of the two ultraluminous X-ray sources: NGC 1313 X-1 and X-2 are presented.
Journal ArticleDOI
NuSTAR Spectroscopy of Multi-Component X-ray Reflection from NGC 1068
Franz E. Bauer,Patricia Arevalo,Dominic J. Walton,Michael Koss,Simonetta Puccetti,Poshak Gandhi,Daniel Stern,David M. Alexander,Mislav Baloković,S. E. Boggs,W. N. Brandt,M. Brightman,Finn E.

Rivers,Cristian Saez,Ezequiel Treister,C. Megan Urry,William W. Zhang +28 more
TL;DR: In this paper, the authors report on observations of NGC1068 with NuSTAR, which provide the best constraints to date on its > 10 keV spectral shape, with no strong continuum or line variability over the past two decades, consistent with its classification as a Compton-thick AGN.
Journal ArticleDOI

TL;DR: In this article, the authors report on the results of spectral fits made to a NuSTAR observation of the black hole GRS 1915+105 in a "plateau" state.
