Multiwavelength Analysis of the Einstein Probe X-ray Transient EP240305a
Ruican Ma, Ye Li, Lian Tao +32
We report multiwavelength observations of EP240305a, an uncatalogued X-ray transient detected by the Einstein Probe on March 5, 2024. The source exhibits distinct characteristics a…
Calibrating the clock of JWST
A. W. Shaw, D. L. Kaplan, P. Gandhi +19
JWST, despite not being designed to observe astrophysical phenomena that vary on rapid time scales, can be an unparalleled tool for such studies. If timing systematics can be contr…
Monitoring Observations of SMC X-1's Excursions (MOOSE) III: X-ray Spectroscopy of a Warped, Precessing Accretion Disc
Rawan Karam, Kristen C. Dage, Bailey E. Tetarenko +11
The MOOSE (Monitoring Observations of SMC X-1 Excursions) program uses the Neutron Star Interior Composition Explorer Mission (NICER) to monitor the high mass X-ray binary SMC X-1…
Rapid Mid-Infrared Spectral-Timing with JWST. I. The prototypical black hole X-ray Binary GRS 1915+105 during a MIR-bright and X-ray-obscured state
P. Gandhi, E. S. Borowski, J. Byrom +44
We present mid-infrared (MIR) spectral-timing measurements of the prototypical Galactic microquasar GRS 1915+105. The source was observed with the Mid-Infrared Instrument (MIRI) on…
The orbital period, black hole mass and distance to the X-ray transient GRS 1716-249 (=N Oph 93)
J. Casares, I. V. Yanes-Rizo, M. A. P. Torres +7
We present evidence for a 0.278(8) d (=6.7 h) orbital period in the X-ray transient GRS 1716-249 (=N Oph 93), based on a superhump modulation detected during the 1995 mini-outburst…
An empirical connection between line-emitting regions and X-rays heating the accretion disc in BH-LMXB MAXI J1820070
B. E. Tetarenko, A. W. Shaw, P. A. Charles
The recurring transient outbursts in low-mass X-ray binaries (LMXBs) provide ideal laboratories to study the accretion process. Unlike their supermassive relatives, LMXBs are far t…
Shedding far-ultraviolet light on the donor star and evolutionary state of the neutron-star LMXB Swift J1858.6-0814
N. Castro Segura, C. Knigge, J. H. Matthews +13
The evolution of accreting X-ray binary systems is closely coupled to the properties of their donor stars. As a result, we can constrain the evolutionary track a system is by estab…
Swift observations of V404 Cyg during the 2015 outburst: X-ray outflows from super-Eddington accretion
S. E. Motta, J. J. E. Kajava, C. Sánchez-Fernández +11
The black-hole binary V404 Cyg entered the outburst phase in June 2015 after 26 years of X-ray quiescence, and with its behaviour broke the outburst evolution pattern typical of mo…
The optical counterpart of the bright X-ray transient Swift J1745-26
T. Muñoz-Darias, A. de Ugarte Postigo, D. M. Russell +13
We present a 30-day monitoring campaign of the optical counterpart of the bright X-ray transient Swift J1745-26, starting only 19 minutes after the discovery of the source. We obse…
Characterizing X-ray binary long-term variability
M. M. Kotze, P. A. Charles
Long-term ("superorbital") periods or modulations have been detected in a wide variety of both low and high-mass X-ray binaries at X-ray and optical wavelengths. A variety of mecha…
Very long-term X-ray variations in LMXBs: solar cycle-like variations in the donor?
M. M. Kotze, P. A. Charles
Long-term monitoring of Low Mass X-ray Binaries (LMXBs) by the All Sky Monitor on board the Rossi X-ray Timing Explorer now covers ~13 yrs and shows that certain LMXB types display…
First science with SALT: peering at the accreting polar caps of the eclipsing polar SDSS J015543.40+002807.2
D. O'Donoghue, D. A. H. Buckley, L. A. Balona +48
We describe briefly the properties of the recently completed Southern African Large Telescope (SALT), along with its first light imager SALTICAM. Using this instrument, we present…
VLT spectroscopy of XTE J2123-058 during quiescence
J. Casares, G. Dubus, T. Shahbaz +2
We present VLT low resolution spectroscopy of the neutron star X-ray transient XTE J2123-058 during its quiescent state. Our data reveal the presence of a K7V companion which contr…
