The EAVN Tiger Team face-to-face meeting
The East Asia VLBI Network (EAVN) is a huge observing network consisting of east Asian radio telescopes. Now there are 5 stations in China, 12 stations in Japan and 4 stations in Korea, therefore the EAVN consists of 21 stations. The EAVN distributes from the Hokkaido of Japan (the northeast) to Urumqi of China (westernmost), and from Seoul of Korea (north) to Kunming of China (south), covering a maximum 6000 km baseline. Among the similar VLBI networks in the world, the EAVN has the most antennas, favorable good (u,v) coverage and sensitivity. The main observing wavelength is a centimeter which enables to observe star forming region, evolved star, X-ray binary and active galactic nuclei (AGNs). Because new radio telescopes are constructing now in the east Asia, the performance of EAVN will become better. EAVN astronomers are expecting a bright future of EAVN that will be able to discover new phenomena and science.
A test operation of EAVN started from 2010, however the performance of each telescope (e.g. diameter, receivers, backends) has variation, limiting routine science operations. In order to push ahead the EAVN observational research, a working group named as Tiger Team was established dueing the 6th EAVN workshop in Jeju Island, Korea in 2013 June. The Tiger Team answers for the test operation of EAVN and troubleshooting. Till now four fringe test experiments have been carried out since 2013 September. In order to review the past experience from the test operation, the Tiger Team is going to organize a technique workshop in Shanghai on July 29th, 2014. Directors of EAVN stations are also invited to join to discuss future collaborations.
