East-Asian sub-mm VLBI workshop

*** From East-Asia to super-massive black holes ***

Date and Venue

        Date : 10/Dec/2012    10:00 -- 17:00
        Venue: Lecture room at NAOJ Mitaka

Aim of the workshop

Event Horizon Telescope (EHT), an international collaboration to build the unique world array of sub-mm VLBI, has been pioneering study of super-massive black holes with ultra-high resolution. In order to summarize the related activities in East Asia and to promote effective collaborations toward their ultimate project goals, we would like to hold a one-day workshop, where researchers working on mm/sub-mm VLBI and/or black hole science in EA region gather, exchange information and thoughts, and discuss the future directions.


Invited Speaker

Kazunori Akiyama (NAOJ, Japan)
Keiichi Asada (ASIAA, Taiwan)
Shep Doeleman (MIT Haystack, USA)
Sohn Bon Wong (KASI, Korea)
Zhi-Qiang Shen (SHAO, China)
