Abstract

We present here the East Asia to Italy Nearly Global VLBI (EATING VLBI) project. How this project started and the evolution of the international collaboration between Korean, Japanese, and Italian researchers to study compact sources with VLBI observations is reported. Problems related to the synchronization of the very different arrays and technical details of the telescopes involved are presented and discussed. The relatively high observation frequency (22 and 43 GHz) and the long baselines between Italy and East Asia produced high-resolution images. We present example images to demonstrate the typical performance of the EATING VLBI array. The results attracted international researchers and the collaboration is growing, now including Chinese and Russian stations. New in progress projects are discussed and future possibilities with a larger number of telescopes and a better frequency coverage are briefly discussed herein.

从东亚到意大利的过去和未来：近乎全球的VLBI

我们在这里介绍东亚到意大利的近全球VLBI（EATING VLBI）项目。报道了该项目是如何开始的，以及韩国、日本和意大利研究人员之间利用VLBI观测研究紧凑源的国际合作的演变。介绍并讨论了与不同阵列的同步相关的问题以及相关望远镜的技术细节。意大利和东亚之间相对较高的观测频率（22和43千兆赫）和较长的基线产生了高分辨率图像。我们展示了示例图像来展示EATING VLBI阵列的典型性能。研究结果吸引了国际研究人员，合作也在不断扩大，现在包括中国和俄罗斯的研究站。本文讨论了正在进行的新项目，并简要讨论了使用更多望远镜和更好频率覆盖范围的未来可能性。
