The Academia Sinica Institute of Astronomy and Astrophysics also known as the Institute of Astronomy and Astrophysics was established in 2010. This was located in Taipei, Taiwan. This is one of the largest university in Taiwan. ASIAAis located in the Astronomy-Mathematics Building (ASMAB) on the campus of National Taiwan University (NTU), with a field office operating in Hawaii. Currently we have a staff over 170 including research fellows, research engineers and scientists, postdoctoral fellows, visiting scholars, assistants and supporting personnel. Astronomy was one of the first few programs initiated when Academia Sinica was founded in China in 1928. Upon the recommendation of the Academician Chia-Chiao Lin, ASIAA Preparatory Office was re-established in 1993 after approval by the Academia Sinica Council. ASIAA is in close collaboration with leading institutes and observatories in Australia, Canada, Japan, US and other countries and also with university groups in Taiwan for advancing astronomical research. Array for Microwave Background Anisotropy (AMiBA) is one of the main projects through our partnership with NTU as part of the Cosmology and Particle Astrophysics (CosPA) effort. Collaboration with National Central University has been underway for a number of years through our partnership on the Taiwan American Occultation Survey (TAOS) project. Our instrumentation group is also in collaboration with National Tsing Hua University (NTHU) for the fabrication of SIS junctions, and Theoretical Institute for Advanced Research in Astrophysics (TIARA) was established in 2004 on the campus of NTHU. Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) is one of the 31 institutes and centers in Academia Sinica aspiring to be at the forefront of astronomical research. Devoting our efforts in specific directions, we have built up core groups in theoretical and experimental astrophysics and instrumentation. Research topics carried out at ASIAA range from solar system, star formation, to extra-galactic science and cosmology. ASIAA also frequently hosts international workshops and conferences. The goal of ASIAA is to become an international research institute engaged in frontier projects, competing and collaborating with the leading research groups worldwide.
