The PanRadio Collaboration’s First Results – The 400-Day Afterglow of GRB 230815A

This episode dives into the extraordinary 400-day observing campaign of Gamma-ray Burst (GRB) 230815A, the first major result from the Panoptic Radio View of Gamma-ray Bursts (“PanRadio GRB”) program.

**The PanRadio Program**

The PanRadio GRB program is a systematic, multi-year radio survey carried out on the Australia Telescope Compact Array (ATCA). Its goal is to provide comprehensive, multi-frequency (1–50 GHz), and high-cadence radio monitoring of all southern *Swift* GRB events, following their afterglow evolution from within an hour to years post-burst. Crucially, this program provides a **more unbiased view** of GRBs, targeting events like G...
