Limits on Fast Radio Bursts at 145 MHz with ARTEMIS, a real-time software backend

A. Karastergiou, J. Chennamangalam, W. Armour +22

Fast Radio Bursts (FRBs), are millisecond radio signals that exhibit dispersion larger than what the Galactic electron density can account for. We have conducted a 1446 hour survey…

Cosmic Dawn and Epoch of Reionization Foreground Removal with the SKA

Emma Chapman, Anna Bonaldi, Geraint Harker +8

The exceptional sensitivity of the SKA will allow observations of the Cosmic Dawn and Epoch of Reionization (CD/EoR) in unprecedented detail, both spectrally and spatially. This we…

Effect of gain and phase errors on SKA1-low imaging quality from 50-600 MHz

David Sinclair, Fred Dulwich, Benjamin Mort +3

Simulations of SKA1-low were performed to estimate the noise level in images produced by the telescope over a frequency range 50-600 MHz, which extends the 50-350 MHz range of the…

Real-time, fast radio transient searches with GPU de-dispersion

Alessio Magro, Aris Karastergiou, Stefano Salvini +3

The identification, and subsequent discovery, of fast radio transients through blind-search surveys requires a large amount of processing power, in worst cases scaling as $\mathcal…
