Rubin Observatory

The NSF Vera C. Rubin Observatory aims to compile the deepest, widest image of the Universe at optical wavelengths ever produced. From 2023 it will conduct a ten year survey of the sky from Cerro Pachon in Chile, using a specially designed 8.4 m diameter telescope with an extremely wide field of view (3.5 degrees).

The primary science drivers of the project, previously known as the Large Synoptic Survey Telescope (LSST), are exploring the nature of dark matter and dark energy, mapping the structure of our Milky Way and nearby galaxies, cataloguing the solar system, and searching for transient objects. First light is expected in 2021, with full survey operations to commence in 2023.

In January 2020, the LSST Project became the NSF Vera C. Rubin Observatory, in honour of renowned US astronomer Dr Vera Rubin. The telescope itself will be known as the Simonyi Survey Telescope in recognition of a significant private donation made early in the construction phase, while the imaging survey program will now be known as the “Legacy Survey of Space and Time” (LSST). The Rubin Observatory boasts a 3.2 gigapixel CCD camera, and by scanning the entire southern sky repeatedly over a ten-year period, it is hoped that the survey will help answer questions about the structure and evolution of the universe.

In 2015, CAASTRO and the LSST Corporation signed a memorandum of agreement to allow a named list of Australian investigators to access data from the LSST. AAL has now novated the agreement and represents Australian astronomers wishing to participate in the LSST project. The 2020 Mid-Term Review of the 2016-2025 Decadal Plan for Australian Astronomy recommended that Australia “Pursue data access to the Legacy Survey of Space and Time via the exchange of time on Australian national facilities.” AAL is now working towards securing LSST survey data access rights for as many Australian astronomers as possible, by providing suitable in-kind contributions that complement the LSST operations and science program.

LSST-related meetings

In May 2019 the first ever [email protected] meeting was held at the University of New South Wales, bringing together over 100 scientists from Australasia, Europe, Africa, and North America to discuss preparatory and planned science activities with LSST.

Anyone interested in doing science with LSST is encouraged to attend the annual LSST Project and Community Workshop, the most recent of which was held virtually on 10-14 August 2020. The next annual meeting will be held in Tucson from 9-13 Aug 2021.

The Australian LSST Workshop 2020 was held via Zoom on 14 Dec 2020, to update the Australian LSST community on the in-kind proposal process, as well as share LSST-related activity within Australia.
