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…
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…
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…
NICER Discovers Spectral Lines During Photospheric Radius Expansion Bursts from 4U 1820-30: Evidence for Burst-driven Winds
T. E. Strohmayer, D. Altamirano, Z. Arzoumanian +14
We report the discovery with the Neutron Star Interior Composition Explorer (NICER) of narrow emission and absorption lines during photospheric radius expansion (PRE) X-ray bursts…
A NICER Discovery of a Low-Frequency Quasi-Periodic Oscillation in the Soft-Intermediate State of MAXI J1535-571
A. L. Stevens, P. Uttley, D. Altamirano +17
We present the discovery of a low-frequency Hz quasi-periodic oscillation (QPO) feature in observations of the black hole X-ray binary MAXI J1535-571 in its soft-inte…
NuSTAR and NICER reveal IGR J17591-2342 as a new accreting millisecond X-ray pulsar
A. Sanna, C. Ferrigno, P. S. Ray +21
We report on the discovery by the Nuclear Spectroscopic Telescope Array (NuSTAR) and the Neutron Star Interior Composition Explorer (NICER) of the accreting millisecond X-ray pulsa…
