Wide-field Optical Astronomy from Antarctica: a Chinese-Australian Workshop


13th August 2012, 10am - 5pm

SiFA, Redfern, Sydney


 

In January 2012 China installed the first of three 0.5 metre wide-field (1.5x2.9 degree) optical imaging telescopes, AST3-1, at the highest point of the Antarctic plateau.

Australia is currently involved in Dome A activities through UNSW's PLATO-A, which will be the primary support platform for AST3, and through equipment to characterise the infrared background and cloud cover at Dome A.

AAL, UNSW and CAASTRO held a 1-day workshop for Australian astronomers to engage with Chinese astronomers involved in the project at Dome A. The objective was to define a plan for Australian contribution to the commencement of significant scientific output from this project.

AST3 Specifications and Data

Update:

Around fifty Australian astronomers attended and engaged with invited Chinese astronomers Ji Yang (Purple Mountain Observatory), Lifan Wang (Purple Mountain Observatory/Texas A&M University) and Jilin Zhou (Nanjing University).

The workshop participants successfully identified key science areas for collaboration between Chinese and Australian astronomers using AST3 data and potential complementary instruments and resources in Australia. These areas were:

  • Supernova physics, including the detection of prompt emission and the spectroscopic and/or photometric follow-up using Australian telescopes;
  • The discovery and characterisation of solar system objects, and exoplanets and their parent stars including detection through transit and lensing observations, and spectroscopic and/or photometric follow-up using Australian telescopes;
  • Stellar structure and evolution, including high precision photometry of variable stars and further spectroscopic and/or photometric follow-up using Australian telescopes;
  • The physics of the dynamic extragalactic Universe, including coordinated synoptic surveys between AST3/CSTAR and appropriate complementary Australian facilities.
