Overview
This workshop invited the Australian community to present science and technology ideas for the post-2030 era that deliver transformational advances with existing or upgraded facilities and new demonstrators in the SKA era.
Inyarrimanha Ilgari Bundara, our Murchison Radio-astronomy Observatory is one of the best sites for radio astronomy observations in the world, and the ATNF should take advantage of its unique environment. With SKA-Mid and SKA-Low telescopes coming online towards the end of the decade for science verification and full operations, and DSA-2000 operating from the late 2020s, it is timely for the community to start planning for post-2030 science and technology pathways.
The ASKAP telescope was built to:
- Help establish an observatory site for the SKA Observatory’s SKA-Low telescope, and
- Demonstrate SKA survey science technologies.
Following the construction of ASKAP, CSIRO ran an open proposal process, and initiated the 5-year Science Survey Projects, which are still in progress.
The first two aims have been achieved, and the surveys are planned to be completed by the end of the decade.
A document was provided outlining a set of broad facility and technology concepts, and the boundary conditions for the discussion. An ASKAP upgrade path is one of the concepts provided for discussion:
Aims of the Workshop
- To canvas ideas on the unique and world-leading science that ATNF can do in the 2030s
- To bring the Australian community into the conversation about the future of mid-high frequency radio astronomy
- To generate new ideas and collaborations within Australia and internationally.
