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…
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 GRB130427A establish a single component synchrotron afterglow origin for the late optical to multi-GeV emission
C. Kouveliotou, J. Granot, J. L. Racusin +17
GRB 130427A occurred in a relatively nearby galaxy; its prompt emission had the largest GRB fluence ever recorded. The afterglow of GRB 130427A was bright enough for the Nuclear Sp…
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…
High-Energy X-rays from J174545.5-285829, the Cannonball: A Candidate Pulsar Wind Nebula Associated with Sgr A East
Melania Nynka, Charles J. Hailey, Kaya Mori +12
We report the unambiguous detection of non-thermal X-ray emission up to 30 keV from the Cannonball, a few-arcsecond long diffuse X-ray feature near the Galactic Center, using the N…
