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…
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…
