Abstract:
Korean Astronomy and Space Science Institute (KASI) started to operate the Taeduk Radio Astronomy Observatory (TRAO) 14-m telescope at (85 – 115) GHz in mid 1980’s and recently installed the SEQUOIA, which is a cryogenic focal plane array with 16 pixels. KASI also started to operate the Korean VLBI Network (KVN) in late 2013. The KVN consists of three 21-m telescopes equipped with the multi-frequency receiving systems, which allow to observe at 22, 43, 86, 129 GHz simultaneously both in single-dish and VLBI modes. The KVN is often combined with the Japanese VLBI network, VERA, to form the KVN and VERA array (KaVA). I will talk about the performance and ongoing key science projects of the KVN/KaVA and TRAO 14-m telescope.
