Structure in the Magnetic Field of the Milky Way Disk and Halo traced by Faraday Rotation

John M. Dickey, Jennifer West, Alec J. M. Thomson +14

Magnetic fields in the ionized medium of the disk and halo of the Milky Way impose Faraday rotation on linearly polarized radio emission. We compare two surveys mapping the Galacti…

The Global Magneto-Ionic Medium Survey: A Faraday Depth Survey of the Northern Sky Covering 1280-1750 MHz

M. Wolleben, T. L. Landecker, K. A. Douglas +17

The Galactic interstellar medium hosts a significant magnetic field, which can be probed through the synchrotron emission produced from its interaction with relativistic electrons.…

The Galactic Magneto-Ionic Medium Survey: Moments of the Faraday Spectra

John M. Dickey, T. L. Landecker, A. J. M. Thomson +11

Faraday rotation occurs along every line of sight in the Galaxy; Rotation Measure (RM) synthesis allows a three-dimensional representation of the interstellar magnetic field. This…

A High-Velocity Cloud Impact Forming a Supershell in the Milky Way

Geumsook Park, Bon-Chul Koo, Ji-hyun Kang +5

Neutral atomic hydrogen (HI) gas in interstellar space is largely organized into filaments, loops, and shells, the most prominent of which are "supershells". These gigantic structu…

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…

Faraday Tomography of the North Polar Spur: Constraints on the distance to the Spur and on the Magnetic Field of the Galaxy

X. H. Sun, T. L. Landecker, B. M. Gaensler +9

We present radio continuum and polarization images of the North Polar Spur (NPS) from the Global Magneto-Ionic Medium Survey (GMIMS) conducted with the Dominion Radio Astrophysical…
