4. Deep learning approach for identification of HII regions and 21-cm signal recovery from SKA reionisation observations

(SKA-Low) will map the distribution of neutral hydrogen during reionisation and produce a tremendous amount of 3D tomographic data. These image cubes will be subject to instrumental limitations, such as systematic noise, foreground contamination, radio frequency interference (RFI) and limited resolution. The challenge of this astronomy image is the undesired astronomical and instrumental noise...

17. Low frequency global sky model

George Carter (Cambridge)

8/31/22, 1:35 PM

Accurate modelling of the Galactic radio foreground is essential for detecting the cosmological 21cm signal. Such a model can aid foreground mitigation in both ongoing searches for the global EoR signal and upcoming efforts by instruments such as HERA to detect the 21cm brightness temperature power spectrum. In this talk, we outline a new low frequency global sky model, the Bayesian Global Sky...
