东亚VLBI网络（EAVN）是东亚的国际VLBI设施，与中国、日本和韩国合作开展。EAVN由在每个东亚国家操作的VLBI阵列组成，包含21个射电望远镜和3个相关器。EAVN将主要工作在6.7 GHz （c波段）、8 GHz （x波段）、22 GHz （k波段）和43 GHz （q波段），尽管它有能力在1.6 - 129 GHz进行观测。到目前为止，我们已经在8 GHz和22 GHz频段进行了8次条纹测试观测，在这两个频率上都成功地探测到了条纹。我们还在大质量恒星形成区域对6.7 GHz甲醇脉泽进行了科学调试观测。EAVN将于2017年下半年投入使用，提供与FAST互补的agn、大质量恒星形成区域和演化恒星的高角分辨率，波长为厘米到毫米。
The East-Asian VLBI Network (EAVN) is the international VLBI facility in East Asia and is conducted in collaboration with China, Japan, and Korea. The EAVN consists of VLBI arrays operated in each East Asian country, containing 21 radio telescopes and three correlators. The EAVN will be mainly operated at 6.7 (C-band), 8 (X-band), 22 (K-band), and 43 GHz (Q-band), although the EAVN has an ability to conduct observations at 1.6 - 129 GHz. We have conducted fringe test observations eight times to date at 8 and 22 GHz and fringes have been successfully detected at both frequencies. We have also conducted science commissioning observations of 6.7 GHz methanol masers in massive star-forming regions. The EAVN will be operational from the second half of 2017, providing complementary results with the FAST on AGNs, massive star-forming regions, and evolved stars with high angular resolution at cm- to mm-wavelengths.
