An efficient method for removing point sources from full-sky radio interferometric maps
Philippe Berger, Niels Oppermann, Ue-Li Pen +1
A new generation of wide-field radio interferometers designed for 21-cm surveys is being built as drift scan instruments allowing them to observe large fractions of the sky. With l…
Accurate Polarization Calibration at 800 MHz with the Green Bank Telescope
Yu-Wei Liao, Tzu-Ching Chang, Cheng-Yu Kuo +4
Polarization leakage of foreground synchrotron emission is a critical issue in HI intensity mapping experiments. While the sought-after HI emission is unpolarized, polarized foregr…
Holographic Beam Mapping of the CHIME Pathfinder Array
Philippe Berger, Laura B. Newburgh, Mandana Amiri +32
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) Pathfinder radio telescope is currently surveying the northern hemisphere between 400 and 800 MHz. By mapping the large s…
