A NuSTAR View of GRS 1716249 in the Hard and Intermediate States
Jiachen Jiang, Felix Fürst, Dominic J. Walton +2
We present a detailed analysis of the spectral properties of the black hole transient GRS 1716-249, based on the archival Swift and NuSTAR observations taken during the outburst of…
The Athena space X-ray Observatory and the astrophysics of hot plasma
Didier Barret, Anne Decourchelle, Andy Fabian +4
The properties (temperature, density, chemical composition, velocity) of hot astrophysical plasma and the physical processes affecting them (heating/cooling, turbulence, shocks, ac…
Lessons learned from 19 years of high-resolution X-ray spectroscopy of galaxy clusters with RGS
C. Pinto, A. C. Fabian, J. S. Sanders +1
The intracluster medium (ICM) contains the vast majority of the baryonic matter in galaxy clusters and is heated to X-ray radiating temperatures. X-ray spectroscopy is therefore a…
Discovery of a soft X-ray lag in the Ultraluminous X-ray Source NGC 1313 X-1
E. Kara, C. Pinto, D. J. Walton +14
Ultraluminous X-ray Sources (ULXs) provide a unique opportunities to probe the geometry and energetics of super-Eddington accretion. The radiative processes involved in super-Eddin…
Astrophysical Black Holes
Andrew C. Fabian, Anthony N. Lasenby
Black holes are a common feature of the Universe. They are observed as stellar mass black holes spread throughout galaxies and as supermassive objects in their centres. Observation…
The Unusual Broadband X-ray Spectral Variability of NGC 1313 X-1 seen with XMMNewton, Chandra and NuSTAR
D. J. Walton, C. Pinto, M. Nowak +19
We present results from the major coordinated X-ray observing program on the ULX NGC 1313 X-1 performed in 2017, combining -, and , focusing on the e…
