Скачать или смотреть How large is the Murchison Widefield Array (MWA) radio telescope?

The MWA is a radio telescope in Western Australia. Currently it consists of 128 tiles, each containing 16 antennas, spaced out in a 4x4 grid. The tiles are spread out in a configuration that maximises science capacity. Distances between the tiles are called baselines. Short baselines allow better imaging of large-scale structures and events such as the Epoch of Reionisation, and long baselines allow fine resolution to image small-scale structures and events, such as solar activity. The tiles are spread out in a configuration that maximises science capacity, by having many small and large baselines, in different orientations. One quarter of the tiles are within a dense 100 m diameter core, with a smooth tile distribution out to 1.5 km diameter and 16 tiles in an outer region of 3 km diameter.
