  1. Science Operations Phil Edwards 14 November 2016 Astronomy and space science

  2. Outline • ATCA • A Rorschach test • Parkes • Mopra • Tidbinbilla • ASKAP • LBA • 2017APR • Feedback Now with added science highlights! Science Operations| Phil Edwards

  3. ATCA • ATCA forum convened last week to discuss rapid response observations • The portal includes information on which observations can be over-ridden by which NAPA • Rapid response science re-opens the debate about whether rapid response projects should be allowed to over-ride any project – so long as that observation can be rescheduled. • Implications for ATCA scheduling Science Operations| Phil Edwards

  5. ATCA Legacy Projects • Legacy Projects are large, coherent science investigations, not reproducible by any combination of smaller projects, that generate data of general and lasting importance to the broad astronomy community. • Legacy Projects typically require more than 2000 hours over the lifetime of the project, with the expectation of over 300 hours to be allocated per semester. • It was initially stated that up to 25% of the observing time may be allocated to Legacy Projects. • An international Time Assignment Committee was tasked with reviewing all Legacy Projects, and with making recommendations for a balanced program of ATCA Legacy Projects. Science Operations | Phil Edwards

  6. ATCA Legacy Projects • The TAC recommended two projects be given the highest priority: • C3132, GAMA Legacy ATCA Southern Survey (GLASS): A Legacy 4cm Survey of the GAMA G23 Field, • C3157, Deep Imaging of the Circum-galactic Medium with ATCA • The TAC also recommended that two further projects be supported at a lower priority: • C3145, Dense Gas Across the Milky Way - The ‘Full-Strength’ MALT45 • C3152, A Comprehensive ATCA Census of High-Mass Cores.​ • C3132 (555 hr) and C3157 (453 hr) were allocated time in 2016OCT, with the intention to start scheduling C3145 and C3152 in 2017APR based on a favourable funding profile. Science Operations | Phil Edwards

  7. ATUC recommendations on Legacy Projects • ATNF should make every effort to ensure that Legacy Projects, once approved, are able to be completed … • ATUC is in principle open to the possibility of increasing the fraction of time devoted to Legacy projects … • …care should be taken to ensure that the diversity of science areas from approved proposals … remains well balanced across the full suite of Legacy and non-Legacy projects. Science Operations| Phil Edwards

  8. Duty Astronomers • DAs play an important role in training observers and as first point of contact, especially after hours • All Astro staff, postdocs, and co-supervised students* are expected to be DA • Being DA is a great way to learn! • … but there are fewer and fewer staff and postdocs who are experienced ATCA observers • The dynamic of being DA has changed with the SOC • As a result, ATCA support staff are having to spend more time training DAs, and responding to after-hours issues Science Operations| Phil Edwards

  9. Duty Astronomers • We are anticipating that ATCA Legacy Projects will be more self-supporting • We will trial Perth based DAs for “Legacy Project weeks” • We are open to suggestions: • Have first time DAs shadow an experienced DA? • Broaden the pool of candidate DAs? • Do away with DAs and require all teams to have a project expert? • Continue the current scheme, but with more training videos and checklists? • Is ATUC aware of any dis-satisfaction with the DA scheme?

  14. Parkes • Presentation from Jimi to follow • Breakthrough Listen is to be allocated 1533 hr per year. • Allocated 535 hr in 2016OCT, so will be allocated 998 hr in 2017APR • Parkes in 2016OCT dominated by P892 (830 hr) and P456 (630 hr) • Four of 28 proposals were not allocated any time, several others received significantly reduced allocations Science Operations | Phil Edwards

  17. Mopra • CSIRO entered an agreement with a UNSW to provide the Mopra telescope for observing for one year from mid-March 2016, on a full cost-recovery basis • This is likely to be extended for at least 6 months • Some Mopra time is being made available for participation in LBA observations • Can Mopra be used as a satellite down-link station? • Could constitute an Australian contribution to WFIRST • Would require some significant changes • “Molecular Line Emission Towards High-Mass Clumps: The MALT90 Catalogue,” Rathborne et al. 2016, PASA, 33, 30 Science Operations | Phil Edwards
