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…
FRB20250613A: a remarkable repeating FRB with apparent millisecond-timescale scattering variations
T. Dial, A. T. Deller, Alexa C. Gordon +8
FRB20250613A is a repeating FRB discovered by the Australian SKA Pathfinder and localised to a low-metallicity dwarf galaxy at a redshift of . FRB 20250613A…
Revisiting GW170817 at milliarcsecond scale: high-precision constraints on jet geometry and
Kelly Gourdji, Adam T. Deller, Chris Flynn +4
The historic detection of gravitational waves from the electromagnetically bright binary neutron star merger GW170817 enabled the first standard siren measurement of Hubble's const…
A PINK update: Improvements to the CELEBI fast radio burst data reduction and analysis pipeline
M. Glowacki, T. Dial, A. Bera +9
Fast radio bursts (FRBs) which are well localised (1") to their host galaxy are tools for studying cosmology and the intergalactic medium. Furthermore, high-time resolution data…
ASKAP J005512.2-255834: A Luminous, Long-Lived Radio Transient at z = 0.1 -- an Orphan Afterglow or an off-nuclear TDE from an IMBH?
Ashna Gulati, Tara Murphy, David L. Kaplan +24
We report the discovery of a slowly evolving, extragalactic radio transient, ASKAP J005512.2--255834 (hereafter ASKAP J0055-2558), identified using the Australian SKA Pathfinder in…
A fast radio burst cyclone in technicolour: evidence of plasma lensing
Pavan A. Uttarkar, Ryan M. Shannon, Kelly Gourdji +9
Fast radio bursts (FRBs) are bright, energetic, radio pulses of extragalactic origin. A dichotomy has emerged in the population: some produce repeat bursts, while the majority do n…
