On May 29, approximately 120 students from Taichung Municipal Taichung First Senior High School in Taiwan visited Kashiwa Campus of the University of Tokyo and listened to the lectures by KAGRA members.

Students of Taichung First Senior High School listening Bin-Hua Hsieh’s lecture

The students arrived at Kashiwa campus early morning on 29th. KAGRA Observatory’s PhD student Bin-Hua Hsieh, who graduated Taichung First Senior High School, took them to the Media Hall in UToko’s Kashiwa Library after touring around buildings of the Institute for Cosmic Ray Research and Kavli Institute for the Physics and Mathematics of the Universe. In the Media Hall, Bin-Hua told the students about the life in the University of Tokyo as a introduction and Assistant Professor Takafumi Ushiba explained about KAGRA’s observation of gravitational waves. Then, Professor Hideyuki Tagoshi lectured on Astrophysics especially about black holes and gravitational waves. In the Q&A session, students asked so keen questions that surprises the lecturers.

The students will visit a high-school in Tokyo to communicate with Japanese students and visit lake Kawaguchi to see beautiful scene of Mt. Fuji after this visit of Kashiwa Campus.
