Expanding our view of the Universe with the Murchison Widefield Array

用Murchison Widefield阵列扩展我们对宇宙的看法： 该项目旨在构建第2阶段Murchison宽场阵列（MWA），以将第1阶段MWA的能力提高一个数量级。当第一批恒星和星系照亮宇宙时，再电离时代（EoR）是宇宙演化的最后一个未被研究的阶段。MWA处于EoR研究和全天巡天天体物理学的前沿，是平方公里阵列（SKA）的唯一低频前兆，也是唯一提供科学质量数据的SKA前兆。该项目将建造第二阶段MWA，将使阵列中的天线数量增加一倍，使最大基线长度增加一倍，并提高我们的全天空调查和EoR能力。

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.
