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…
Planck intermediate results. XLIV. The structure of the Galactic magnetic field from dust polarization maps of the southern Galactic cap
Planck Collaboration, N. Aghanim, M. I. R. Alves +165
We study the statistical properties of interstellar dust polarization at high Galactic latitude, using the Stokes parameter Planck maps at 353 GHz. Our aim is to advance the unders…
The Euclidean distribution of Fast Radio Bursts
Niels Oppermann, Liam Connor, Ue-Li Pen
We investigate whether current data on the distribution of observed flux densities of Fast Radio Bursts (FRBs) are consistent with a constant source density in Euclidean space. We…
Constraints on the FRB rate at 700-900 MHz
Liam Connor, Hsiu-Hsien Lin, Kiyoshi Masui +5
Estimating the all-sky rate of fast radio bursts (FRBs) has been difficult due to small-number statistics and the fact that they are seen by disparate surveys in different regions…
