Introduction of the Workshop

Chile is one of the best site for the ground-based astronomy on the Earth, and now many large facilities in broad wavelength range from the optical to the radio are operated. Japanese institutes and universities are also running various telescopes in Chile, such as ALMA, TAO, NANTEN, and ASTE. However, interactions between astronomical communities of Chile and Japan is still limited. The aim of this workshop is to nurture interaction between researchers in both Chile and Japan, to promote exchange of students and post-docs, and to expand ongoing collaborations.
