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…

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…

Advances in Understanding High-Mass X-ray Binaries with INTEGRAL and Future Directions

Peter Kretschmar, Felix Fürst, Lara Sidoli +48

High mass X-ray binaries are among the brightest X-ray sources in the Milky Way, as well as in nearby Galaxies. Thanks to their highly variable emissions and complex phenomenology,…

Possible Periodic Windowed Behavior in SGR1935+2154 SGR Bursts

Bruce Grossan

Two repeating FRB sources, FRB180916 (CHIME/FRB Collaboration, 2020a) and FRB121102 (Rajwade, et al., 2020, Cruces, et al., 2021) display periodic windowed behavior (PWB) in the ti…

The obscured X-ray binaries V404 Cyg, Cyg X-3, V4641 Sgr, and GRS 1915+105

Karri I. I. Koljonen, John A. Tomsick

V404 Cyg, Cyg X-3, V4641 Sgr, and GRS 1915+105 are among the brightest X-ray binaries and display complex behavior in their multiwavelength emission. Apart from Cyg X-3, the other…

Evidence for Returning Disk Radiation in the Black Hole X-ray Binary XTE J1550-564

Riley M. T. Connors, Javier A. Garcia, Thomas Dauser +7

We explore the accretion properties of the black hole X-ray binary \j1550\ during its outbursts in 1998/99 and 2000. We model the disk, corona, and reflection components of X-ray s…

Studying the Reflection Spectra of the New Black Hole X-ray Binary Candidate MAXI J1631-479 Observed by NuSTAR: A Variable Broad Iron Line Profile

Yanjun Xu, Fiona A. Harrison, John A. Tomsick +5

We present results from the Nuclear Spectroscopic Telescope Array (NuSTAR) observations of the new black hole X-ray binary candidate MAXI J1631-479 at two epochs during its 2018-20…

Evidence for Disk Truncation at Low Accretion States of the Black Hole Binary MAXI J1820+070 Observed by NuSTAR and XMM-Newton

Yanjun Xu, Fiona A. Harrison, John A. Tomsick +3

We present results from NuSTAR and XMM-Newton observations of the new black hole X-ray binary MAXI J1820+070 at low accretion rates (below 1% of the Eddington luminosity). We detec…

A mildly relativistic outflow from the energetic, fast-rising blue optical transient CSS161010 in a dwarf galaxy

D. L. Coppejans, R. Margutti, G. Terreran +35

We present X-ray and radio observations of the Fast Blue Optical Transient (FBOT) CRTS-CSS161010 J045834-081803 (CSS161010 hereafter) at t=69-531 days. CSS161010 shows luminous X-r…
