Simultaneous NICER and NuSTAR Observations of the Ultra-compact X-ray Binary 4U 1543-624
R. M. Ludlam, A. D. Jaodand, J. A. García +8
We present the first joint NuSTAR and NICER observations of the ultra-compact X-ray binary (UCXB) 4U 1543624 obtained in 2020 April. The source was at a luminosity of $L_{0.5-50…
The Awakening Beast in the Seyfert 1 Galaxy KUG 1141+371 I
Jiachen Jiang, Huaqing Cheng, Luigi C. Gallo +10
KUG 1141+371 is a Seyfert 1 galaxy that shows a simultaneous flux increase in the optical and UV bands in the past decade. For instance, the latest Swift observation in 2019 shows…
MAXI J1820+070 with NuSTAR II. Flaring during the hard to soft state transition with a long soft lag
D. J. K. Buisson, A. C. Fabian, P. Gandhi +6
We continue the analysis of NuSTAR data from the recent discovery outburst of MAXI J1820+070 (optical counterpart ASASSN-18ey), focussing on an observation including unusual flarin…
Discovery of thermonuclear (Type I) X-ray bursts in the X-ray binary Swift J1858.6-0814 observed with NICER and NuSTAR
D. J. K. Buisson, D. Altamirano, P. Bult +22
Swift J1858.6-0814 is a recently discovered X-ray binary notable for extremely strong variability (by factors in soft X-rays) in its discovery state. We present the detectio…
Measuring the masses of magnetic white dwarfs: A NuSTAR Legacy Survey
A. W. Shaw, C. O. Heinke, K. Mukai +11
The hard X-ray spectrum of magnetic cataclysmic variables can be modelled to provide a measurement of white dwarf mass. This method is complementary to radial velocity measurements…
Soft X-ray emission lines in the X-ray binary Swift J1858.6-0814 observed with XMM-Newton-RGS: disc atmosphere or wind?
D. J. K. Buisson, D. Altamirano, M. Díaz Trigo +11
We find soft X-ray emission lines from the X-ray binary Swift J1858.6-0814 in data from XMM-Newton-RGS: N VII, O VII and O VIII, as well as notable residuals short of a detection a…
