12th East Asian VLBI Workshop 2019
Since the release of the first EAVN call for proposal in April 2018, the EAVN array is now in its real operation with 10 stations (KaVA, Tianma, Nanshan and Nobeyama). The EAVW-2019 will be the first meeting after this milestone, while an increasing number of exciting results are coming out with KaVA, the core array of EAVN. We will discuss and highlight various science topics studied by EAVN/KaVA as well as by individual VLBI facilities VERA/KVN/CVN/JVN. This will include active galactic nuclei, star formation, evolved stars, astrometry, micro quasars, pulsars, transients, multi-messenger science etc. We will also highlight various ongoing developments of the array capability and instruments as well as the near-future expansion of the network into Ibaraki, Yamaguchi, Kunming, Thailand, Italy, Australia etc. Moreover, the VLBI community in East Asia is increasingly involved with EHT and SKA. Therefore we will also discuss how EAVN can play a unique role in the era of such huge facilities. This will include "EAVN-high" that includes JCMT/GLT and "EAVN-low" that includes FAST, as well as joining a global VLBI network.

User's Meeting
2019 Radio Telescope User's Meeting
Dear all,

We are pleased to announce the “2019 Radio telescope User’s Meeting”, which will be held on August 27 - 30, 2019 at Seoul national university in pyeongchang

The current status, recent scientific results, and future plans of KVN, TRAO, ALMA and JCMT will be shared at the meeting. Anyone who utilizes or wants to know about these radio telescopes is strongly encouraged to attend and will be more than welcome. We plan to have individual sessions dedicated to each of the telescopes (ALMA/JCMT, TRAO and KVN). At the end of the sessions, there will be plenty of opportunities to make questions or suggestions on their operation and capability enhancement. In addition, we will have a session for discussing about possible radio facilities in the near future: e.g., extended KVN, SKA, and a South Pole facility.

We look forward to seeing you at Seoul national university in pyeongchang.

If you have any question or comment, please feel free to contact the LOC

Since the 1st East Asian VLBI Workshop (EAVW2008) held at Shanghai Astronomical Observatory (SHAO), China, the EAVW2018 is the 11th workshop. In particular, this time will be a special meaningful workshop for actual scientific discussions and collaborations. It is because the First Call for Proposal for the East Asian VLBI Network (EAVN) was announced in April and its official operation starts from September 2018.

The EAVW2018 will include recent progress and status of EAVN and focus on various VLBI science topics in the fields of AGN, evolved stars, star-forming regions, and Galactic astrometry etc. In addition, Extended KVN project has been promoted by KASI based on the successful operational results of the 1st step KVN project. The Shanghai 65m Tianma telescope has started full operation and the 110m telescope (QiTai radio telescope: QTT) by Xinjiang Astronomical Observatory will begin construction. Furthermore, the Thailand 40m telescope by NARIT begins to be built and the Greenland telescope by ASIAA starts to enhance the capability of Submillimeter VLBI.

These rapid developments of East Asian radio astronomy will lead to close VLBI collaborations in both science and instrumentation at the EAVW2018.
