A Spatially Resolved Radio Spectral Index Study of the Dwarf Irregular Galaxy NGC\,1569
Jonathan Westcott, Elias Brinks, Luke Hindson +2
We study the resolved radio-continuum spectral energy distribution of the dwarf irregular galaxy, NGC 1569, on a beam-by-beam basis to isolate and study its spatially resolved radi…
Calibration and Stokes Imaging with Full Embedded Element Primary Beam Model for the Murchison Widefield Array
M. Sokolowski, T. Colegate, A. T. Sutinjo +22
The Murchison Widefield Array (MWA), located in Western Australia, is one of the low-frequency precursors of the international Square Kilometre Array (SKA) project. In addition to…
The Spectral Energy Distribution of Powerful Starburst Galaxies I: Modelling the Radio Continuum
T J Galvin, N Seymour, J Marvil +24
We have acquired radio continuum data between 70\,MHz and 48\,GHz for a sample of 19 southern starburst galaxies at moderate redshifts () with the aim of separat…
A high resolution foreground model for the MWA EoR1 field: model and implications for EoR power spectrum analysis
P. Procopio, R. B. Wayth, J. Line +23
The current generation of experiments aiming to detect the neutral hydrogen signal from the Epoch of Reionisation (EoR) is likely to be limited by systematic effects associated wit…
New insights into the interstellar medium of the dwarf galaxy IC 10: connection between magnetic fields, the radio--infrared correlation and star formation
Aritra Basu, Sambit Roychowdhury, Volker Heesen +4
We present the highest sensitivity and angular resolution study at 0.32 GHz of the dwarf irregular galaxy IC\,10, observed using the Giant Metrewave Radio Telescope, probing $\sim4…
H2O Southern Galactic Plane Survey (HOPS): Paper III - Properties of Dense Molecular Gas across the Inner Milky Way
S. N. Longmore, A. J. Walsh, C. R. Purcell +22
The H2O Southern Galactic Plane Survey (HOPS) has mapped 100 square degrees of the Galactic plane for water masers and thermal molecular line emission using the 22-m Mopra telescop…
