MeerKAT Radio Telescope:
An international team of astronomers has employed the MeerKAT radio telescope to investigate giant radio galaxies in the field of the Cosmological Evolution Survey (COSMOS).
- MeerKAT is a connected array of radio telescopes located in the Northern Cape province of South Africa.
- It was originally known as the Karoo Array Telescope (KAT), which would consist of 20 receptors. When the South African government increased the budget to allow the building of 64 receptors, the team renamed it “MeerKAT”, – i.e., “more of KAT”.
- It is part of South Africa’s contribution to the global Square Kilometre Array (SKA) project, which aims to build the largest and most sensitive radio telescope in the world.
- It is a precursor instrument to the mid-frequency component of the Square Kilometre Array (SKA).
- It uses radio signals from space to study the evolution of the universe and everything it contains.
- It comprises 64 dishes, each 13.5 metres in diameter, with maximum separations of 8 km.
- The received signals travel to a subterranean processor building that combines them and allows the telescopes to work together as a single instrument.
- It is currently the most powerful radio interferometer at centimeter wavelengths.
