A Small Satellite Version of a Broad-band Soft X-ray Polarimeter

Herman L. Marshall, Sarah N. T. Heine, Alan Garner +16

We describe a new implementation of a broad-band soft X-ray polarimeter, substantially based on a previous design. This implementation, the Pioneer Soft X-ray Polarimeter (PiSoX) i…

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…

The X-ray reflection spectrum of the radio-loud quasar 4C 74.26

Anne Lohfink, Andrew Fabian, David Ballantyne +11

The relativistic jets created by some active galactic nuclei are important agents of AGN feedback. In spite of this, our understanding of what produces these jets is still incomple…

The NuSTAR Hard X-ray Survey of the Norma Arm Region

Francesca M. Fornasini, John A. Tomsick, JaeSub Hong +32

We present a catalog of hard X-ray sources in a square-degree region surveyed by NuSTAR in the direction of the Norma spiral arm. This survey has a total exposure time of 1.7 Ms, a…

The distribution of radioactive Ti in Cassiopeia A

Brian W. Grefenstette, Chris L. Fryer, Fiona A. Harrison +28

The distribution of elements produced in the inner-most layers of a supernova explosion is a key diagnostic for studying the collapse of massive stars. Here we present the results…
