The Effect of Foreground Mitigation Strategy on EoR Window Recovery

Emma Chapman, Saleem Zaroubi, Filipe Abdalla +3

The removal of the Galactic and extragalactic foregrounds remains a major challenge for those wishing to make a detection of the Epoch of Reionization 21-cm signal. Multiple method…

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…

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…

Analysing the impact of far-out side-lobes on the imaging performance of the SKA-LOW telescope

Benjamin Mort, Fred Dulwich, Nima Razavi-Ghods +2

The Square Kilometre Array's Low Frequency instrument (SKA-LOW) will be the most sensitive aperture array ever used for radio astronomy, and will operate in the under-sampled regim…

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…
