Expanding our view of the Universe with the Murchison Widefield Array: 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.

通过Murchison Widefield阵列扩大我们对宇宙的看法： 该项目旨在建立一个2阶段Murchison广场阵列（MWA），以通过数量级提高1阶段MWA的功能。当第一颗恒星和星系点亮宇宙时，电回离时（EOR）是宇宙进化的最后一个未研究的阶段。 MWA位于EOR研究的前沿和全天空调查的天体物理学，是平方公里阵列（SKA）的唯一低频前体，也是唯一提供科学质量数据的SKA前体。构建2期MWA的项目将使阵列中的天线数量增加一倍，将最大基线长度增加一倍，并提高我们的全天空调查和EOR功能。
