Foregrounds and their mitigation
Emma Chapman, Vibor Jelić
The low-frequency radio sky is dominated by the diffuse synchrotron emission of our Galaxy and extragalactic radio sources related to Active Galactic Nuclei and star-forming galaxi…
Predictions for the 21cm-galaxy cross-power spectrum observable with LOFAR and Subaru
Dijana Vrbanec, Benedetta Ciardi, Vibor Jelić +8
The 21cm-galaxy cross-power spectrum is expected to be one of the promising probes of the Epoch of Reionization (EoR), as it could offer information about the progress of reionizat…
Effects of the sources of reionization on 21-cm redshift-space distortions
Suman Majumdar, Hannes Jensen, Garrelt Mellema +11
The observed 21-cm signal from the epoch of reionization will be distorted along the line-of-sight by the peculiar velocities of matter particles. These redshift-space distortions…
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…
Foreground Removal using FastICA: A Showcase of LOFAR-EoR
Emma Chapman, Filipe B. Abdalla, Geraint Harker +6
We introduce a new implementation of the FastICA algorithm on simulated LOFAR EoR data with the aim of accurately removing the foregrounds and extracting the 21-cm reionization sig…
