The GLEAM 4-Jy (G4Jy) Sample: I. Definition and the catalogue

1 code implementation27 Apr 2020 Sarah V. White, Thomas M. O. Franzen, Chris J. Riseley, O. Ivy Wong, Anna D. Kapińska, Natasha Hurley-Walker, Joseph R. Callingham, Kshitij Thorat, Chen Wu, Paul Hancock, Richard W. Hunstead, Nick Seymour, Jesse Swan, Randall Wayth, John Morgan, Rajan Chhetri, Carole Jackson, Stuart Weston, Martin Bell, Bi-Qing For, B. M. Gaensler, Melanie Johnston-Hollitt, André Offringa, Lister Staveley-Smith

Of these G4Jy sources, 78 are resolved by the MWA (Phase-I) synthesised beam ($\sim$2 arcmin at 200 MHz), and we label 67% of the sample as 'single', 26% as 'double', 4% as 'triple', and 3% as having 'complex' morphology at $\sim$1 GHz (45-arcsec resolution).

The GLEAM 4-Jy (G4Jy) Sample: II. Host-galaxy identification for individual sources

This is the GaLactic and Extragalactic All-sky MWA (GLEAM) Survey, and we have previously used a combination of visual inspection, cross-checks against the literature, and internal matching to identify the 'brightest' radio-sources ($S_{\mathrm{151MHz}} >$ 4 Jy) in the extragalactic catalogue (Galactic latitude, $|b| >$ 10 deg).

Galactic synchrotron emissivity measurements between 250° < l < 355° from the GLEAM survey with the MWA

1 code implementation16 Nov 2016 H. Su, N. Hurley-Walker, C. A. Jackson, N. M. McClure-Griffiths, S. J. Tingay, L. Hindson, P. Hancock, R. B. Wayth, B. M. Gaensler, L. Staveley-Smith, J. Morgan, M.

Using a low-frequency radio telescope, the Murchison Widefield Array (MWA), we measure the free-free absorption of this Galactic synchrotron emission by intervening HII regions along the line of sight.

A model of diffuse Galactic Radio Emission from 10 MHz to 100 GHz

2 code implementations12 Feb 2008 Angelica de Oliveira-Costa, Max Tegmark, B. M. Gaensler, Justin Jonas, T. L. Landecker, Patricia Reich

Understanding diffuse Galactic radio emission is interesting both in its own right and for minimizing foreground contamination of cosmological measurements.
