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…
The Homogeneous MeerKAT and Swift/XRT X-ray Binary Radio:X-ray Plane
Justine Crook-Mansour, Rob Fender, Andrew Hughes +22
During the hard and quiescent spectral states in X-ray binaries, a non-linear correlation is observed between radio and X-ray luminosities, providing a valuable tool to probe the c…
SXP 31.0 -- the 2025 near-Eddington double X-ray outburst after 26 years of quiescence
Malcolm J. Coe, Thomas M. Gaudin, Itumeleng M. Monageng +5
SXP 31.0 is an X-ray source in the Small Magellanic Cloud (SMC) that was first identified as a Be X-ray Binary (BeXRB) system when it went into X-ray outbusrst in 1998. It is now k…
Detection of an Extremely Luminous Radio Counterpart to the Be/X-ray Binary A0538-66
Justine Crook-Mansour, Rob Fender, Alex Andersson +14
We present the discovery of radio emission from the Be/X-ray binary A0538-66 with the Australian Square Kilometre Array Pathfinder (ASKAP), and results from a subsequent weekly mon…
An extremely fast fading population II dwarf nova candidate: caught spectroscopically on the rise
Natasha Van Bemmel, Jielai Zhang, Jeff Cooke +14
We present AT2022kak, a rapidly evolving optical transient discovered by the KiloNova and Transients Program (KNTraP). This interesting burst exhibited extremely fast evolution, wi…
A relativistic jet from a neutron star breaking out of its natal supernova remnant
K. V. S. Gasealahwe, K. Savard, I. M. Monageng +10
The young neutron star X-ray binary, Cir X-1, resides within its natal supernova remnant and experiences ongoing outbursts every 16.5 days, likely due to periastron passage in an e…
