Stories from Siding Spring Observatory Please return to reception Stories from Siding Spring Observatory PHOTOGRAPHS BY STAFF OF THE AUSTRALIAN ASTRONOMICAL OBSERVATORY Siding Spring Observatory sits on a mountaintop in the Warrumbungle Range, 400 km northwest of Sydney and 25 km west of the town of Coonabarabran. Run by the Australian National University, it is Australia’s most important site for optical astronomy. On 13 January 2013 a bushfire swept through the observatory. Despite damage to some buildings, the telescopes were unharmed and are now back at work. The photos in this exhibition tell stories of life and work on the mountain. They were taken by staff of the Australian Astronomical Observatory (AAO), which operates two telescopes there: the 4-m Anglo- Australian Telescope (AAT) and the UK Schmidt telescope.

Please return to reception THE AUSTRALIAN ASTRONOMICAL OBSERVATORY The Australian Astronomical Observatory, a division of the Department of Industry, Innovation, Climate Change, Science, Research and Tertiary Education, operates the Anglo-Australian and UK Schmidt telescopes on behalf of the Australian astronomical community. The AAO exists to provide world-class optical and infrared observing facilities that enable Australian astronomers to do excellent science. It is a world leader in astronomical research and in the development of innovative telescope instrumentation, and also plays an active role in the formulation of long-term plans for Australian astronomy. The telescopes of the AAO are located in the Warrumbungle mountains near Coonabarabran in northern New South Wales. Harley Wood, NSW Government Astronomer at Sydney Observatory from 1943 to 1974, suggested this location, among others, during site-selection visits he made throughout the state. The site is now recognised as one of the darkest astronomical observing sites in the world. This exhibition was developed by the Australian Astronomical Observatory, with support from Sydney Observatory and the Powerhouse Museum.

  • WG 3.2 National-Scale Facilities
    National Facilities A report to the National Committee for Astronomy for the Australian Astronomy Decadal Plan 2006-2015 By Working Group 3.2 September 2005 Executive Summary Australia’s national facilities for observational astronomy are the Anglo-Australian Observatory (AAO) and the Australia Telescope National Facility (ATNF). In the period covered by this Decadal Plan the United Kingdom will substantially reduce its contribution to the operations budget of the AAO. In consequence, a major issue for this WG to consider is the future funding of the AAO. In addition to the AAO and ATNF, several Australian universities operate observing facilities that have a significant role at a national level: either by offering observing time to outside users or by providing infrastructure as in the case of the ANU’s Siding Spring Observatory (SSO). Rather than duplicate the detailed discussions of these facilities, the three Facilities WG chairs agreed to assign facilities like SSO into one or the other WGs: this was for practical reasons and does not imply any judgement about the status of the respective university facilities. Our discussions at this stage of the Decadal Plan process were independent of the scientific priorities from the science WGs, so are based mainly on strategic issues informed by the submissions we received and our own experience as users (and senior staff) of national facilities. The lack of a detailed science case at this stage of the process makes it hard to assign relative ranks to all the facilities discussed. However we have identified the top and bottom items: • In all our discussions there was unqualified support for the AAO and ATNF as our two national facilities.

  • The 6Df Galaxy Survey Is a Very Effective Means of Determining the True Mass Distribution in the Local Universe
    **TITLE** ASP Conference Series, Vol. **VOLUME***, **YEAR OF PUBLICATION** **NAMES OF EDITORS** The 6dF Galaxy Survey Ken-ichi Wakamatsu Faculty of Engineering, Gifu University, Gifu 501-1192, Japan Matthew Colless Mount Stromlo & Siding Spring Observatories, ACT 2611, Australia Tom Jarrett IPAC, Caltech, MS 100-22, Pasadena, CA 91125, USA Quentin Parker Macquarie University, Sydney 2109, Australia William Saunders Anglo-Australian Observatory, Epping NSW 2121, Australia Fred Watson Anglo-Australian Observatory, Coonabarabran NSW 2357, Australia Abstract. The 6dF Galaxy Survey (6dFGS) 1 is a spectroscopic sur- vey of the entire southern sky with |b| > 10◦, based on the 2MASS near infrared galaxy catalog. It is conducted with the 6dF multi-fiber spec- trograph attached to the 1.2-m UK Schmidt Telescope. The survey will produce redshifts for some 170,000 galaxies, and peculiar velocities for about 15,000 and is expected to be complete by June 2005. arXiv:astro-ph/0306104v1 5 Jun 2003 1. Introduction In order to reveal large-scale structures at intermediate and large distances, ex- tensive galaxy redshift surveys have been carried out, e.g. the 2dFGRS and SDSS, and the Hubble- and Subaru-deep field surveys. There is now an ur- gent need to study the large-scale structure of the Local Universe that can be compared with the above deeper surveys.

Description: Washington, DC: National Aeronautics and Space Administration, Office of Communications, NASA History Division, [2020] | Series: NASA history series ; sp-2020-4237 | Includes bibliographical references and index. | Summary: “Dr. Christopher Gainor’s Not Yet Imagined documents the history of NASA’s Hubble Space Telescope (HST) from launch in 1990 through 2020. This is considered a follow-on book to Robert W. Smith’s The Space Telescope: A Study of NASA, Science, Technology, and Politics, which recorded the development history of HST. Dr. Gainor’s book will be suitable for a general audience, while also being scholarly. Highly visible interactions among the general public, astronomers, engineers, govern- ment officials, and members of Congress about HST’s servicing missions by Space Shuttle crews is a central theme of this history book. Beyond the glare of public attention, the evolution of HST becoming a model of supranational cooperation amongst scientists is a second central theme. Third, the decision-making behind the changes in Hubble’s instrument packages on servicing missions is chronicled, along with HST’s contributions to our knowledge about our solar system, our galaxy, and our universe.

  • TAIPAN Instrument Fibre Positioner and Starbug Robots: Engineering Overview Nicholas F
    TAIPAN Instrument Fibre Positioner and Starbug Robots: Engineering Overview Nicholas F. Staszak*, Jon Lawrence, David M. Brown, Rebecca Brown, Ross Zhelem, Michael Goodwin, Kyler Kuehn, Nuria P. F. Lorente, Vijay Nichani, Lew Waller, Scott Case, Robert Content, Andrew M. Hopkins, Urs Klauser, Naveen Pai, Rolf Mueller, Slavko Mali, Minh V. Vuong Australian Astronomical Observatory, 105 Delhi Rd., North Ryde, NSW 2113, Australia. ABSTRACT TAIPAN will conduct a stellar and galaxy survey of the Southern sky. The TAIPAN positioner is being developed as a prototype for the MANIFEST instrument on the GMT. The design for TAIPAN incorporates 150 optical fibres (with an upgrade path to 300) situated within independently controlled robotic positioners known as Starbugs. Starbugs allow precise parallel positioning of individual fibres, thus significantly reducing instrument configuration time and increasing the amount of observing time. Presented is an engineering overview of the UKST upgrade of the completely new Instrument Spider Assembly utilized to support the Starbug Fibre Positioning Robot and current status of the Starbug itself. Keywords: fibre positioning systems, Starbugs, MANIFEST, TAIPAN, UKST, GMT 1. INTRODUCTION TAIPAN, currently nearing completion, is a multi-object parallel-positioning fibre-optic spectrograph designed for the UK Schmidt Telescope at Siding Spring Observatory in northern New South Wales, Australia. The instrument will be used to perform galaxy and stellar surveys across the whole Southern hemisphere sky, over a 5 year period. The fibre positioning portion of TAIPAN consists of a complete refurbishment of the UKST interior spider which replaces the 6DF serial positioning instrument used for the RAVE and 6dfG surveys. The TAIPAN Instrument Structure provides a stiff, low deflection, spider to interface the necessary support infrastructure to allow the Starbug Positioning Robots to operate, while maintaining a minimum obscuration of the incoming beam.

Received YYY; in original form ZZZ ABSTRACT The Transiting Exoplanet Survey Satellite (TESS) has already begun to discover what will ultimately be thousands of exoplanets around nearby cool bright stars. These potential host stars must be well-understood to accurately characterize exoplanets at the individual and population levels. We present a catalogue of the chemo-kinematic properties of 2,218,434 stars in the TESS Candidate Target List using survey data from Gaia DR2, APOGEE, GALAH, RAVE, LAMOST, and photometrically-derived stellar properties from SkyMapper. We compute kinematic thin disc, thick disc, and halo membership probabilities for these stars and find that though the majority of TESS targets are in the thin disc, 4% of them reside in the thick disc and <1% of them are in the halo. The TESS Objects of Interest in our sample also display similar contributions from the thin disc, thick disc, and halo with a majority of them being in the thin disc. We also explore metallicity and [α/Fe] distributions for each Galactic component and show that each cross-matched survey exhibits metallicity and [α/Fe] distribution functions that peak from higher to lower metallicity and lower to higher [α/Fe] from the thin disc to the halo.
