KASI-KOPRI Workshop for Antarctic Scientific Research Collaboration
이 워크샵은 천문연구원과 극지연구소가 협력하여 남극에서의 천문우주과학 관련 활동을 크게 증진시키고자 함입니다. 이와 관련한 여러 과학적 활동에 대한 제안을 논의하고, 천문연과 극지연과의 상호협력을 발전시키고자 합니다. 국제적으로 남극의 중요성은 잘 알려져 있습니다. 우리나라는 극지연구소가 중심이 되어 이미 남극에 세종기지, 장보고 기지, 아라온호 등 많은 관련 활동을 해오고 있습니다. 극지연구소는 현재 대형 프로젝트인 K-Route 개척 사업을 진행중에 있습니다. 앞으로 이와 함께 진행될 남극대륙 내륙기지 건설을 위하여 관련 기관 및 연구자들 간에 보다 큰 협력을 진행하고자 남극과 관련된 여러 발표와 논의를 가질 예정입니다. 남극에서의 활동에는 천문우주과학의 거의 모든 분야가 참여가능한 만큼 관련 연구자들과 학회의 많은 관심과 참여를 기대합니다.

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.

User's Meeting
2018 Radio Telescope User's Meeting
We are pleased to announce the “2018 Radio telescope User’s Meeting”, which will be held on August 16 - 17, 2018 at the Korea Astronomy and Space Science Institute (KASI) in Daejeon, Korea. The meeting will be hosted and organized by the Radio Astronomy Divisions of the Korean Astronomical Society and KASI.

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 KASI.

Working Group Meeting
2017 KaVA/EAVN Joint Science Working Group Meeting
The KVN and VERA Array (KaVA) started its regular operation from 2013 and is conducting more than 1000-hour observations per year. KaVA consists of 7 radio telescopes with the baseline lengths of 300 - 2,300 km, enabling us to obtain very high-quality images at both 22 and 43 GHz.

KaVA Science Working Group (SWG) is organized in four astronomy areas (AGN, Evolved Stars, Galactic Astrometry, and Star-Forming Regions) including members from not only Korea and Japan but also many other countries. In 2016, KaVA SWG's activities were expanded to cover further science topics to be obtained with the East-Asian VLBI Network (EAVN).

The workshop entitled "KaVA/EAVN Joint Science Working Group Meeting" aims at conducting face-to-face discussion in each SWG, exchanging information between SWGs, and introducing the latest results obtained with KaVA and other VLBI arrays. How to promote scientific research with EAVN will also be discussed.

On the other hand, KaVA has also started the Large Programs (LPs) for three science topics from 2015 in order to fully utilize KaVA's array capabilities and to maximize scientific output. The first-term observations have been completed and preliminary results are already obtained. Interim review of KaVA Large Program is also held as part of the workshop to review progress and accomplishments of first-term LP, and to examine how to proceed with the second-term LP.
