GOTO identification and broadband modelling of the counterpart to the SVOM GRB 250818B
S. Belkin, G. P. Lamb, K. Ackley +61
Rapid localisation and follow-up of gamma-ray bursts (GRBs) increasingly rely on low-latency triggers from new missions coupled to wide-field robotic optical facilities. We present…
SN 2024cld: unveiling the complex mass-loss histories of evolved supergiant progenitors to core collapse supernovae
T. L. Killestein, M. Pursiainen, R. Kotak +52
Pre-explosion mass loss in supernova (SN) progenitors is a crucial unknown factor in stellar evolution, yet has been illuminated recently by the diverse zoo of interacting transien…
GRB 241105A: A test case for GRB classification and rapid r-process nucleosynthesis channels
Dimple, B. P. Gompertz, A. J. Levan +85
Gamma-ray bursts (GRBs) offer a powerful window to probe the progenitor systems responsible for the formation of heavy elements through the rapid neutron capture (r-) process, than…
A Sibling of AR Scorpii: SDSS J230641.47244055.8 and the Observational Blueprint of White Dwarf Pulsars
N. Castro Segura, I. Pelisoli, B. T. Gänsicke +21
Radio pulsating white dwarf (WD) systems, known as WD pulsars, are non-accreting binary systems where the rapidly spinning WD interacts with a low-mass companion producing pulsed n…
GOTO065054+593624: a 8.5 mag amplitude dwarf nova identified in real time via Kilonova Seekers
T. L. Killestein, G. Ramsay, M. Kennedy +62
Dwarf novae are astrophysical laboratories for probing the nature of accretion, binary mass transfer, and binary evolution -- yet their diverse observational characteristics contin…
Eruptive mass loss less than a year before the explosion of superluminous supernovae: I. The cases of SN 2020xga and SN 2022xgc
A. Gkini, C. Fransson, R. Lunnan +47
We present photometric and spectroscopic observations of SN 2020xga and SN 2022xgc, two hydrogen-poor superluminous supernovae (SLSNe-I) at and , respectiv…
