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…
XMM-Newton Campaign On Ultraluminous X-ray Source NGC 1313 X-1: Wind vs. State Variability
C. Pinto, D. J. Walton, E. Kara +12
Most ultraluminous X-ray sources (ULXs) are thought to be powered by neutron stars and black holes accreting beyond the Eddington limit. If the compact object is a black hole or a…
The nuclear environment of the NLS1 Mrk 335: obscuration of the X-ray line emission by a variable outflow
M. L. Parker, A. L. Longinotti, N. Schartel +12
We present XMM-Newton, NuSTAR, Swift and Hubble Space Telescope observations of the Narrow-line Seyfert 1 galaxy Mrk 335 in a protracted low state in 2018 and 2019. The X-ray flux…
MAXI J1820+070 with NuSTAR I. An increase in variability frequency but a stable reflection spectrum: coronal properties and implications for the inner disc in black hole binaries
D. J. K. Buisson, A. C. Fabian, D. Barret +10
MAXI J1820+070 (optical counterpart ASASSN-18ey) is a black hole candidate discovered through its recent very bright outburst. The low extinction column and long duration at high f…
High Density Reflection Spectroscopy: II. the Density of the Inner Black Hole Accretion Disc in AGN
Jiachen Jiang, Andrew C. Fabian, Thomas Dauser +7
We present a high density disc reflection spectral analysis of a sample of 17 Seyfert 1 galaxies to study the inner disc densities at different black hole mass scales and accretion…
CIELO-RGS: a catalogue of soft X-ray ionized emission lines
Junjie Mao, J. S. Kaastra, M. Guainazzi +9
High-resolution X-ray spectroscopy has advanced our understanding of the hot Universe by revealing physical properties like kinematics, temperature, and abundances of the astrophys…
