NuSTAR reveals the hidden nature of SS433
M. J. Middleton, D. J. Walton, W. Alston +25
SS433 is the only Galactic binary system known to persistently accrete at highly super-critical (or hyper-critical) rates, similar to those in tidal disruption events, and likely n…
NuSTAR observations of Mrk 766: distinguishing reflection from absorption
D. J. K. Buisson, M. L. Parker, E. Kara +14
We present two new NuSTAR observations of the narrow line Seyfert 1 (NLS1) galaxy Mrk 766 and give constraints on the two scenarios previously proposed to explain its spectrum and…
NuSTAR Hard X-ray Observation of the Gamma-ray Binary Candidate HESS J1832-093
Kaya Mori, E. V. Gotthelf, Charles J. Hailey +13
We present a hard X-ray observation of the TeV gamma-ray binary candidate HESS J1832-093 coincident with supernova remnant (SNR) G22.7-0.2 using the Nuclear Spectroscopic Telescope…
A deep X-ray view of the bare AGN Ark120. IV. XMM-Newton and NuSTAR spectra dominated by two temperature (warm, hot) Comptonization processes
D. Porquet, J. N. Reeves, G. Matt +16
We perform an X-ray spectral analysis of the brightest and cleanest bare AGN known so far, Ark 120, in order to determine the process(es) at work in the vicinity of the SMBH. We pr…
Looking at A 0535+26 at low luminosities with NuSTAR
Ralf Ballhausen, Katja Pottschmidt, Felix Fürst +12
We report on two NuSTAR observations of the HMXB A 0535+26 taken toward the end of its normal 2015 outburst at very low keV luminosities of erg/s an…
Sagittarius A* High Energy X-ray Flare Properties During NuSTAR Monitoring of the Galactic Center from 2012 to 2015
Shuo Zhang, Frederick K. Baganoff, Gabriele Ponti +17
Understanding the origin of the flaring activity from the Galactic center supermassive black hole, Sagittarius A*, is a major scientific goal of the NuSTAR Galactic plane survey ca…
