Searching for outbursts from Symbiotic Binaries in GOTO and ATLAS data
G. Ramsay, K. Ackley, S. Belkin +46
Symbiotic Binaries contain a white dwarf accreting material from a red giant star through a wind. We present the results of a search for outbursts from Symbiotic Binaries using pho…
Time-Domain Photometry and Activity Evolution of Interstellar Comet 3I/ATLAS with BHTOM
A. Fraser Gillan, Åukasz Wyrzykowski, PrzemysÅaw J. MikoÅajczyk +69
Time-domain photometric monitoring is essential for characterizing cometary evolution, particularly for rare interstellar objects with limited observing opportunities. We aimed to…
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…
Discovery and Analysis of Afterglows from Poorly Localised GRBs with the Gravitational-wave Optical Transient Observer (GOTO) All-sky Survey
Amit Kumar, B. P. Gompertz, B. Schneider +86
Gamma-ray bursts (GRBs), particularly those detected by wide-field instruments such as the Fermi/GBM, pose a challenge for optical follow-up due to their large initial localisation…
EP241021a: a months-duration X-ray transient with luminous optical and radio emission
Shu Xinwen, Yang Lei, Yang Haonan +82
We present the discovery of a peculiar X-ray transient, EP241021a, by the Einstein Probe (EP) mission, and the results from multiwavelength follow-up observations. The transient wa…
The day-long, repeating GRB 250702BDE / EP250702a: A unique extragalactic transient
Andrew J. Levan, Antonio Martin-Carrillo, Tanmoy Laskar +42
Gamma-ray bursts (GRBs) are singular outbursts of high-energy radiation with durations typically lasting from milliseconds to minutes and, in extreme cases, a few hours. They are a…
