Foreground modelling via Gaussian process regression: an application to HERA data
Abhik Ghosh, Florent Mertens, Gianni Bernardi +70
The key challenge in the observation of the redshifted 21-cm signal from cosmic reionization is its separation from the much brighter foreground emission. Such separation relies on…
Radio Interferometric Calibration Using a Complex Student's t-distribution and Wirtinger Derivatives
Ulrich Armel Mbou Sob, Hertzog Landman Bester, Oleg Smirnov +2
Radio interferometric gain calibration can be biased by incomplete sky models and radio frequency interference, resulting in calibration artefacts that can restrict the dynamic ran…
Visualization of Fractional Integrals
Trienko Lups Grobler
We presented a novel geometric interpretation of the Riemann-Liouville fractional integral. We found that a Riemann-Liouville integral can be thought of as the area obtained by sum…
Constraining Polarized Foregrounds for EOR Experiments II: Polarization Leakage Simulations in the Avoidance Scheme
C. D. Nunhokee, G. Bernardi, S. A. Kohn +7
A critical challenge in the observation of the redshifted 21-cm line is its separation from bright Galactic and extragalactic foregrounds. In particular, the instrumental leakage o…
