Demonstration of hybrid foreground removal on CHIME data
Haochen Wang, Kiyoshi Masui, Kevin Bandura +15
The main challenge of 21 cm cosmology experiments is astrophysical foregrounds which are difficult to separate from the signal due to telescope systematics. An earlier study has sh…
Holographic Beam Measurements of the Canadian Hydrogen Intensity Mapping Experiment (CHIME)
Mandana Amiri, Arnab Chakraborty, Simon Foreman +17
We present the first results of the holographic beam mapping program for the Canadian Hydrogen Intensity Mapping Experiment (CHIME). We describe the implementation of the holograph…
Beam Maps of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Measured with a Drone
Will Tyndall, Alex Reda, J. Richard Shaw +14
We present beam measurements of the CHIME telescope using a radio calibration source deployed on a drone payload. During test flights, the pulsing calibration source and the telesc…
Faraday tomography with CHIME: the `tadpole' feature G137+7
Nasser Mohammed, Anna Ordog, Rebecca A. Booth +27
A direct consequence of Faraday rotation is that the polarized radio sky does not resemble the total intensity sky at long wavelengths. We analyze G137+7, which is undetectable in…
CHIME/FRB Outriggers: KKO Station System and Commissioning Results
Adam E. Lanman, Shion Andrew, Mattias Lazda +43
Localizing fast radio bursts (FRBs) to their host galaxies is an essential step to better understanding their origins and using them as cosmic probes. The CHIME/FRB Outrigger progr…
