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…
Classifying white dwarfs from multi-object spectroscopy surveys with machine learning
James Munday, Pier-Emmanuel Tremblay, Ingrid Pelisoli +5
With tens to hundreds of spectra of white dwarfs being taken each night from multi-object spectroscopic surveys, automated spectral classification is essential as part of efficient…
Nested, asymmetric H-He circumstellar shells in the Type Icn/Ibn SN 2024abvb
The INTEL Collaboration, J. P. Anderson, C. Aster +17
Interacting transients probe mass loss in the final stages of stellar evolution; however, the geometry and timing of multi-episode mass loss remain poorly constrained. SN 2024abvb…
Giant outbursts of clumpy material preceding Type II supernova 2024qiw
T. Nagao, H. Kuncarayakti, K. Maeda +6
Observations of core-collapse supernovae suggest that some massive stars undergo intense mass loss shortly before explosion, but the underlying mechanisms remain unknown. Here we r…
