Faraday depth similarities across scales with LoTSS & DRAGONS
Anna Ordog, Rebecca A. Booth, Ana Erceg +5
Faraday rotation of diffuse Galactic synchrotron emission is a powerful tracer of the complex, magnetised interstellar medium (ISM), whose structures span a wide range of spatial s…
A three-dimensional model for the reversal in the local large-scale interstellar magnetic field
Rebecca A. Booth, Anna Ordog, Jo-Anne Brown +8
We probe the three-dimensional geometry of the large-scale Galactic magnetic field within 1 kpc of the Sun using the Dominion Radio Astrophysical Observatory (DRAO) Global Magneto-…
Detection of the Cosmological 21 cm Signal in Auto-correlation at z ~ 1 with the Canadian Hydrogen Intensity Mapping Experiment
CHIME Collaboration, Mandana Amiri, Kevin Bandura +36
We present the first detection of the cosmological 21 cm intensity mapping signal in auto-correlation at z ~ 1 with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). Usin…
GMIMS-DRAGONS: A Faraday Depth Survey of the Northern Sky Covering 350-1030 MHz
Anna Ordog, Rebecca A. Booth, T. L. Landecker +25
Polarized synchrotron emission at meter to centimeter wavelengths provides an effective tracer of the Galactic magnetic field. Calculating Faraday depth, the most useful parameter…
The Polarisation Sky Survey of the Universe's Magnetism (POSSUM): Science Goals and Survey Description
B. M. Gaensler, G. H. Heald, N. M. McClure-Griffiths +57
The Australian SKA Pathfinder (ASKAP) offers powerful new capabilities for studying the polarised and magnetised Universe at radio wavelengths. In this paper, we introduce the Pola…
A pioneering experiment combining single-antenna and aperture-synthesis data to measure Faraday rotation with GMIMS and the CGPS
Anna Ordog, Jo-Anne C. Brown, T. L. Landecker +11
Structures in the magnetoionic medium exist across a wide range of angular sizes owing to large-scale magnetic fields coherent over the Galactic spiral arms combined with small-sca…
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…
Characterization of the John A. Galt telescope for radio holography with CHIME
Alex Reda, Tristan Pinsonneault-Marotte, Meiling Deng +21
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) will measure the 21 cm emission of astrophysical neutral hydrogen to probe large scale structure at redshifts z=0.8-2.5.…
Cosmic Magnetism
Jennifer West, Jo-Anne Brown, Bryan Gaensler +9
Magnetic fields are involved in every astrophysical process on every scale: from planetary and stellar interiors to neutron stars, stellar wind bubbles and supernova remnants; from…
The Global Magneto-Ionic Medium Survey: Polarimetry of the Southern Sky from 300 to 480 MHz
M. Wolleben, T. L. Landecker, E. Carretti +12
Much data on the Galactic polarized radio emission has been gathered in the last five decades. All-sky surveys have been made, but only in narrow, widely spaced frequency bands, an…
A High Resolution Survey of the Galactic Plane at 408 MHz
Albert Tung, Roland Kothes, Tom Landecker +6
The interstellar medium is a complex 'ecosystem' with gas constituents in the atomic, molecular, and ionized states, dust, magnetic fields, and relativistic particles. The Canadian…
Gain and Polarization Properties of a Large Radio Telescope from Calculation and Measurement: The John A. Galt Telescope
Xuan Du, Thomas L. Landecker, Timothy Robishaw +3
Measurement of the brightness temperature of extended radio emission demands knowledge of the gain (or aperture efficiency) of the telescope and measurement of the polarized compon…
The JCMT 12CO(3-2) Survey of the Cygnus X Region: I. A Pathfinder
M. Gottschalk, R. Kothes, H. E. Matthews +2
Cygnus X is one of the most complex areas in the sky. This complicates interpretation, but also creates the opportunity to investigate accretion into molecular clouds and many subs…
Correcting the Polarization Leakage Phases and Amplitudes Throughout the Primary Beam of an Interferometer
R. I. Reid, A. D. Gray, T. L. Landecker +1
Polarimetric observations are affected by leakage of unpolarized light into the polarization channels, in a way that varies with the angular position of the source relative to the…
