NuSTAR and Swift observations of the black hole binary GS 1354-64
Abstract
We report on NuSTAR and Swift observations of the black hole binary GRS 1354-64 during its 2015 hard state outburst. Thermal continuum emission is not detected from the accretion disk. However, disk reflection is prominent in the sensitive NuSTAR spectra, and it is utilized to constrain the inner extent of the cool accretion disk, and to set a limit on the spin of this black hole. The Swift data are used to examine how much UV flux is direct, and how much is reprocessed, by examining UV versus X-ray flux trends over the outburst. Overall, modern observatories provide a much improved view of this well-known black hole X-ray binary.
