First hard X-ray detection of the non-thermal emission around the Arches cluster: morphology and spectral studies with NuSTAR
Roman A. Krivonos, John A. Tomsick, Franz E. Bauer +15
The Arches cluster is a young, densely packed massive star cluster in our Galaxy that shows a high level of star formation activity. The nature of the extended non-thermal X-ray em…
Cutoff in the hard X-ray spectra of the ultraluminous X-ray sources HoIX X-1 and M82 X-1
Sergey Sazonov, Alexander Lutovinov, Roman Krivonos
Using data from the XMM-Newton and INTEGRAL observatories, we have detected a cutoff at energies above 10 keV in the X-ray spectra of the ultraluminous X-ray sources HoIX X-1 and M…
NuSTAR and INTEGRAL observations of a low/hard state of 1E1740.7-2942
Lorenzo Natalucci, John A. Tomsick, Angela Bazzano +19
The microquasar 1E1740.7-2942, also known as the "Great Annihilator", was observed by NuSTAR in the Summer of 2012. We have analyzed in detail two observations taken ~2 weeks apart…
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…
