A signal dedispersion algorithm for imaging-based transient searches
Cristian Di Pietrantonio, Marcin Sokolowski, Christopher Harris +2
Dedispersion is the computational process of correcting for the frequency-dependent time delay affecting a radio signal that propagates through the interstellar and intergalactic m…

BLINK: an End-To-End GPU High Time Resolution Imaging Pipeline for Fast Radio Burst Searches with the Murchison Widefield Array
Cristian Di Pietrantonio, Marcin Sokolowski, Christopher Harris +2
Petabytes of archival high time resolution observations have been captured with the Murchison Widefield Array. The search for Fast Radio Bursts within these using established softw…

High-Time Resolution GPU Imager for FRB searches at low radio frequencies
M. Sokolowski, G. Aniruddha, C. Di Pietrantonio +5
Fast Radio Bursts (FRBs) are millisecond dispersed radio pulses of predominately extra-galactic origin. Although originally discovered at GHz frequencies, most FRBs have been detec…
