Optical outburst evolution of the transient black hole X-ray binary Swift J1727.8-1613: Disc response to jet ejections and late-outburst emergence of powerful disc winds

N. Castro Segura, K. Solomons, J. M. Corral-Santana +22

Swift J1727.81613 is a newly discovered transient low-mass X-ray binary harbouring a stellar-mass () black hole. We present state-resolved VLT/X-Shooter optical…

Discovering Cataclysmic Variables from the Rubin Observatory LSST

D. A. H. Buckley, Y. Tampo, P. Szkody +8

The Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) will provide a windfall of new transients and variable sources. Here we have performed mock observation simul…

MeerKAT discovery of a hyperactive repeating fast radio burst source

J. Tian, I. Pastor-Marazuela, K. M. Rajwade +17

We present the discovery and localisation of a repeating fast radio burst (FRB) source from the MeerTRAP project, a commensal fast radio transient search programme using the MeerKA…

DW Cnc: a micronova with a negative superhump and a flickering spin

M. Veresvarska, S. Scaringi, C. Littlefield +15

Magnetic accreting white dwarfs in cataclysmic variables have been known to show bursts driven by different physical mechanisms; however, the burst occurrence is much rarer than in…

Contemporaneous optical-radio observations of a fast radio burst in a close galaxy pair

K. Y. Hanmer, I. Pastor-Marazuela, J. Brink +20

We present the MeerKAT discovery and MeerLICHT contemporaneous optical observations of the Fast Radio Burst (FRB) 20230808F, which was found to have a dispersion measure of $\mathr…

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…
