Science with the Murchison Widefield Array - the Low frequency precursor to the SKA

Abstract: The Murchison Widefield Array (MWA) is the first fully operational precursor to the Square Kilometre Array (SKA). Since Phase I of the MWA was completed in late 2012, the instrument has collected over 10 TB of data spanning the frequency range of 72 – 300 MHz. This has resulted in over 80 publications and 1500 citations for a diverse range of science covering radio galaxies, pulsars, galactic magnetism, the ionosphere, exoplanets, EoR, supernova remnants, HII regions, relics and halos in galaxy clusters. Highlights of this work include the completion of a sky survey south of +30 degrees, detection of plasma ducts in the ionosphere, discovery of large numbers of new supernova remnants and a very large number of new diffuse sources (relics and halos) in clusters. I will discuss the MWA as an instrument and present the science highlights of the first 4 years of operations, in particular focusing on the work associated with galaxy clusters. If time permits I will briefly describe the current upgrade process for the telescope.
