Project topic

Mapping the Galaxy in 3-D using observations of HII region absorption with the MWA

Project details

Synchrotron emission pervades the Galactic plane at low radio frequencies, originating from cosmic ray electrons interacting with the Galactic magnetic field. Using a low-frequency radio telescope, the Murchison Widefield Array (MWA), I measure the free-free absorption of this Galactic synchrotron emission by intervening HII regions along the line of sight. These absorption measurements allow me to calculate the Galactic cosmic-ray electron emissivity behind and in front of HII regions. This will enable testing of the spatial distribution of cosmic-ray electrons with a known Galactic magnetic field.

News

Synchrotron emissivity measurements in the whole GLEAM survey has been finished [22 July 2018]

The initial measurements have been reported [10 November 2017]
