On the distance to the black hole X-ray binary Swift J1727.81613
Benjamin J. Burridge, James C. A. Miller-Jones, Arash Bahramian +11
We review the existing distance estimates to the black hole X-ray binary Swift J1727.81613, present new radio and near-UV spectra to update the distance constraints, and discuss…
Characterising the short-orbital period X-ray transient Swift J1910.2-0546
J. M. Corral-Santana, P. Rodriguez-Gil, M. A. P. Torres +13
SwiftJ1910.2-0546 is a Galactic X-ray transient discovered during a bright outburst in 2012. We use time-series optical photometry and spectroscopy to estimate the orbital period,…
The kangaroo's first hop: the early fast cooling phase of EP250108a/SN 2025kg
Rob A. J. Eyles-Ferris, Peter G. Jonker, Andrew J. Levan +52
Fast X-ray transients (FXTs) are a rare and poorly understood population of events. Previously difficult to detect in real time, the launch of the Einstein Probe with its wide fiel…
EP 250108a/SN 2025kg: Observations of the most nearby Broad-Line Type Ic Supernova following an Einstein Probe Fast X-ray Transient
J. C. Rastinejad, A. J. Levan, P. G. Jonker +66
With a small sample of fast X-ray transients (FXTs) with multi-wavelength counterparts discovered to date, the progenitors of FXTs and their connections to gamma-ray bursts (GRBs)…
EP240801a/XRF 240801B: An X-ray Flash Detected by the Einstein Probe and Implications of its Multiband Afterglow
Shuai-Qing Jiang, Dong Xu, Agnes P. C. van Hoof +89
We present multiband observations and analysis of EP240801a, a low-energy, extremely soft gamma-ray burst (GRB) discovered on August 1, 2024 by the Einstein Probe (EP) satellite, w…
State-dependent signatures of jets and winds in the optical and infrared spectrum of the black hole transient GX 3394
A. Ambrifi, D. Mata Sánchez, T. Muñoz-Darias +14
GX 3394 is one of the prototypical black hole X-ray transients, exhibiting recurrent outbursts that allow detailed studies of black hole accretion and ejection phenomena. In thi…
