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…
A Comprehensive X-ray Report on AT2019wey
Yuhan Yao, S. R. Kulkarni, K. C. Gendreau +25
Here, we present MAXI, SWIFT, NICER, NuSTAR and Chandra observations of the X-ray transient AT2019wey (SRGA J043520.9+552226, SRGE J043523.3+552234). From spectral and timing analy…
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…
X-ray Spectral and Timing evolution of MAXI J1727-203 with NICER
K. Alabarta, D. Altamirano, M. Méndez +16
We present a detailed X-ray spectral and variability study of the full 2018 outburst of MAXI J1727-203 using NICER observations. The outburst lasted approximately four months. Spec…
NICER-NuSTAR Observations of the Neutron Star Low-Mass X-ray Binary 4U 1735-44
R. M. Ludlam, E. M. Cackett, J. A. García +8
We report on the first simultaneous and observations of the neutron star (NS) low-mass X-ray binary 4U 173544, obtained in 2018 August. The source was at a lumi…
The Soft State of the Black Hole Transient Source MAXI J1820+070: Emission from the Edge of the Plunge Region?
A. C. Fabian, D. J Buisson, P. Kosec +18
The Galactic black hole X-ray binary MAXI J1820+070 had a bright outburst in 2018 when it became the second brightest X-ray source in the Sky. It was too bright for X-ray CCD instr…
A strongly changing accretion morphology during the outburst decay of the neutron star X-ray binary 4U 1608-52
J. van den Eijnden, N. Degenaar, R. M. Ludlam +7
It is commonly assumed that the properties and geometry of the accretion flow in transient low-mass X-ray binaries (LMXBs) significantly change when the X-ray luminosity decays bel…
A NICER View of Spectral and Profile Evolution for Three X-ray Emitting Millisecond Pulsars
Dominick M. Rowan, Zaynab Ghazi, Lauren Lugo +17
We present two years of Neutron star Interior Composition Explorer (NICER) X-ray observations of three energetic rotation-powered millisecond pulsars (MSPs): PSRs B1937+21, B1821-2…
