First Results from the PanRadio Gamma-Ray Burst Collaboration: The 400-day Afterglow of GRB 230815A

James K. Leung, Gemma E. Anderson, Alexander J. van der Horst +26

We introduce the PanRadio Gamma-ray Burst (GRB) program carried out on the Australia Telescope Compact Array: a systematic, multi-year, radio survey of all southern $\textit{Swift}…

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…

The radio flare and multi-wavelength afterglow of the short GRB 231117A: energy injection from a violent shell collision

G. E. Anderson, G. P. Lamb, B. P. Gompertz +64

We present the early radio detection and multi-wavelength modeling of the short gamma-ray burst (GRB) 231117A at redshift . The Australia Telescope Compact Array automatic…

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…

Constraints on LIGO/Virgo Compact Object Mergers from Late-time Radio Observations

Ashna Gulati, Tara Murphy, Dougal Dobie +6

We present results from a search for radio afterglows of compact object mergers conducted with the Australian SKA Pathfinder. We used data from four epochs of the Rapid ASKAP Conti…

Extremely luminous optical afterglow of an energetic gamma-ray burst GRB 230204B

Rahul Gupta, Judith Racusin, Vladimir Lipunov +47

Robotic telescope networks play an important role in capturing early and bright optical afterglows, providing critical insights into the energetics and emission mechanisms of GRBs.…
