The ultraluminous X-ray sources NGC 1313 X-1 and X-2: a broadband study with NuSTAR and XMM-Newton
Matteo Bachetti, Vikram Rana, Dominic J. Walton +16
We present the results of NuSTAR and XMM-Newton observations of the two ultraluminous X-ray sources (ULX) NGC 1313 X-1 and X-2. The combined spectral bandpass of the two satellites…
NuSTAR discovery of a luminosity dependent cyclotron line energy in Vela X-1
Felix Fuerst, Katja Pottschmidt, Joern Wilms +13
We present NuSTAR observations of Vela X-1, a persistent, yet highly variable, neutron star high-mass X-ray binary (HMXB). Two observations were taken at similar orbital phases but…
NuSTAR observations of magnetar 1E 1841-045
Hongjun An, Romain Hascoet, Victoria M. Kaspi +18
We report new spectral and temporal observations of the magnetar 1E 1841-045 in the Kes 73 supernova remnant obtained with the Nuclear Spectroscopic Telescope Array (NuSTAR). Combi…
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…
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…
The Reflection Component from Cygnus X-1 in the Soft State Measured by NuSTAR and Suzaku
John A. Tomsick, Michael A. Nowak, Michael Parker +21
The black hole binary Cygnus X-1 was observed in late-2012 with the Nuclear Spectroscopic Telescope Array (NuSTAR) and Suzaku, providing spectral coverage over the ~1-300 keV range…
