DESCRIPTION:Square Kilometre Array is an international project to build the
  largest and the most sensitive radio telescope that has ever existed. Its
  low frequency component\, SKA-Low\, will operate in the frequency range 5
 0-350 MHz and will be located in Western Australia at Murchison Radio Astr
 onomy Observatory. The construction of the SKA-Low that will stretch to 65
  km to accommodate 130\,000 antennas has begun in 2021. In preparation to 
 the construction of such an engineering beast\, a few versions of Aperture
  Array Verification Systems (AAVS) have been deployed and tested. AAVS ver
 sion 2 (AAVS2) is a prototype of only one of the required 512 stations of 
 the spiral-shaped SKA-Low array. AAVS2 consists of 256 dual-polarized log-
 periodic antennas distributed semi-randomly on a wire-mesh ground. Accurat
 e simulated performance of the antennas with low-noise amplifiers is cruci
 al for calibration and sensitivity calculations. This presentation starts 
 from some background information about aperture arrays in radio astronomy 
 and continues with the latest advances in engineering development of SKA-L
 ow.\n\nCo-sponsored by: Morteza Shahpari\n\nSpeaker(s): Dr Maria Kovaleva\
