Flip-flop QPO changes during state transitions: a case study of GX339-4 and theoretical discussion
D. J. K. Buisson, G. Marcel, V. López-Barquero +3
We analyse the 2021 outburst from the black hole X-ray binary GX339-4 observed by NICER around the hard to soft transition, when the system exhibits flip-flops between two distinct…
The thermonuclear X-ray bursts of 4U 1730-22
Peter Bult, Giulio C. Mancuso, Tod E. Strohmayer +11
We present observations of the historic transient 4U 1730-22 as observed with the Neutron Star Interior Composition Explorer (NICER). After remaining in quiescence since its 1972 d…
A NuSTAR and Swift View of the Hard State of MAXI J1813-095
Jiachen Jiang, Douglas J. K. Buisson, Thomas Dauser +9
We present an analysis of the NuSTAR and Swift spectra of the black hole candidate MAXI J1813-095 in a failed-transition outburst in 2018. The NuSTAR observations show evidence of…
A persistent ultraviolet outflow from an accreting neutron star binary transient
N. Castro Segura, C. Knigge, K. S. Long +31
All disc-accreting astrophysical objects produce powerful outflows. In binaries containing neutron stars (NS) or black holes, accretion often takes place during violent outbursts.…
Extending the baseline for SMC X-1's spin and orbital behavior with NuSTAR stray light
McKinley C. Brumback, B. W. Grefenstette, D. J. K. Buisson +10
StrayCats, the catalog of NuSTAR stray light observations, contains data from bright X-ray sources that fall within crowded source regions. These observations offer unique addition…
Radius Constraints from Reflection Modeling of Cygnus X-2 with NuSTAR and NICER
R. M. Ludlam, E. M. Cackett, J. A. García +8
We present a spectral analysis of NuSTAR and NICER observations of the luminous, persistently accreting neutron star (NS) low-mass X-ray binary Cygnus X-2. The data were divided in…
