Simultaneous NICER and NuSTAR Observations of the Ultra-compact X-ray Binary 4U 0614+091

David Moutard, Renee Ludlam, Javier A. García +13

We present the first joint NuSTAR and NICER observations of the ultra-compact X-ray binary (UCXB) 4U 0614+091. This source shows quasi-periodic flux variations on the timescale of…

Sub-second infrared variability from the archetypal accreting neutron star 4U~1728-34

F. M. Vincentelli, P. Casella, A. Borghese +23

We report on the first simultaneous high-time resolution X-ray and infrared (IR) observations of a neutron star low mass X-ray binary in its hard state. We performed h…

The accretion/ejection link in the neutron star X-ray binary 4U 1820-30 I: A boundary layer-jet coupling?

A. Marino, T. D. Russell, M. Del Santo +16

The accretion flow / jet correlation in neutron star (NS) low-mass X-ray binaries (LMXBs) is far less understood when compared to black hole (BH) LMXBs. In this paper we will prese…

The RS Oph outburst of 2021 monitored in X-rays with NICER

Marina Orio, Keith Gendreau, Morgan Giese +19

The 2021 outburst of the symbiotic recurrent nova RS Oph was monitored with the Neutron Star Interior Composition Explorer Mission (NICER) in the 0.2-12 keV range from day one afte…

Thermonuclear Type-I X-ray Bursts and Burst Oscillations from the Eclipsing AMXP Swift J1749.4-2807

A. C. Albayati, P. Bult, D. Altamirano +10

Swift J1749.4-2807 is the only known eclipsing accreting millisecond X-ray pulsar. In this paper, we report on 7 thermonuclear (Type-I) X-ray bursts observed by NICER during its 20…

Millihertz X-ray variability during the 2019 outburst of black hole candidate Swift~J1357.20933

Aru Beri, Vishal Gaur, Phil Charles +8

Swift J1357.20933 is a black-hole candidate X-ray transient, which underwent its third outburst in 2019, during which several multi-wavelength observations were carried out.~Her…
