Time Domain Astronomical Surveys from Antarctica

Lifan Wang, Texas A&M University

13 Dec 2012 - 15:00

The Antarctica plateau is likely the best site for ground based astronomy. There are several major advantages of doing astronomy at Dome A: (1) The atmospheric turbulance boundary layer is only around 14 meters at Dome A, meaning free atmospheric seeing of about 0.3 arcsec can be achieved regularly; (2) The temperature reaches -70 - 80 C during winter time, which makes the site ideal for astronomy in the infrared and terraherts wavelengths; (3) The continuous dark time during Austral winter enables intensive time domain astronomy; (4) The mild weather allows for open air telescope with no dome and optical cameras with no nitrogen cooling. I will show recent progresses in astronomical buildup at Dome A, Antarctica, and discuss the prospects of time domain searches for supernovae, exoplanets, and other transient phenomena in astronomy. The Antarctica Survey Telescopes (AST3) project is pioneering optical astronomy from Antarctica, and recent operations show tremendous potential. I will also give a brief overview of the 2.5 meter Kunlun Dark Universe Survey Telescope (KDUST) which aims at high resolution cosmological surveys of about 0.3 arcsec from Dome A.
