Expanding Our View Of The Universe With The Murchison Widefield Array

Abstract

This project aims to build a Phase 2 Murchison Widefield Array (MWA) to boost the capabilities of the Phase 1 MWA by an order of magnitude. The Epoch of Reionisation (EoR), when the first stars and galaxies lit up the universe, is the last unstudied phase of cosmic evolution. The MWA is at the frontier of EoR research and all-sky survey astrophysics, is the only low frequency precursor for the Square Kilometre Array (SKA), and is the only SKA precursor delivering science quality data. This project to construct a Phase 2 MWA would double the number of antennas in the array, double the maximum baseline length, and boost our all-sky survey and EoR capabilities.
