Rapid Response Triggering for Radio Transients with the SKA Observatory
G. E. Anderson, S. I. Chastain, A. P. Curtin +10
Rapid-response triggering is when a telescope is able to automatically respond to an external or internal astronomical transient alert, causing it to rapidly repoint at that positi…
GRB 240205B: A Reverse Shock Detected in Rapid Response Radio Observations
S. I. Chastain, G. E. Anderson, A. J. van der Horst +6
Here we present broadband radio modeling of GRB 240205B, using observations with the Australia Telescope Compact Array (ATCA) and the South African MeerKAT radio telescope. Our obs…
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}…
Design and Commissioning of an LWA Swarm Station: The Long Wavelength Array -- North Arm
C. A. Taylor, J. Dowell, G. B. Taylor +9
Modern radio interferometers are designed with increasingly sprawling geographical footprints, offering enhanced sensitivity and resolution. However, managing such extensive facili…
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…
Commensal Transient Searches with MeerKAT in Gamma-Ray Burst and Supernova Fields
S. I. Chastain, A. J. van der Horst, A. Horesh +6
The sensitivity and field of view of the MeerKAT radio telescope provides excellent opportunities for commensal transient searches. We carry out a commensal transient search in sup…
