2 CSIRO - ATNF: Science Priorities Science directions for ATNF facilities 1.International Context 2.Likely high impact science 3.Specific requirements 4.Priorities 5.A year in the life Process ASA presentation: week of 7 July Science road-show: week of 21 July Documents v1 released: 8 August Web forum: through mid-September Documents v2 prepared: 10 October ATSC review: 15/16 October Documents v3 release: late October Future ATNF Operations paper to CSIRO Executive: November ATNF Operations v3 (including detailed planning): December Science Planning for 2010 – 2015

3 CSIRO - ATNF: Science Priorities Science Planning for 2010 – 2015 Bear 2010 – 2015 time-frame in mind Recall priority of: Delivering ASKAP Operating all ATNF facilities with sustainable budget Focus on- and exploit complementarities Only modest up-grades likely practical, but don’t stop innovative thinking! Extensive community (national and international) input incorporated

4 CSIRO - ATNF: Science Priorities ASKAP Priority Science 2010 – Understanding galaxy formation and gas evolution in the nearby Universe through extragalactic HI surveys; 2.The characterization of the radio transient sky through detection and monitoring (including VLBI) of transient and variable sources; 3.Determining the evolution, formation and population of galaxies across cosmic time via high resolution, confusion limited, continuum surveys; 4.Exploring the evolution of magnetic fields in galaxies over cosmic time through polarization surveys.

5 ATCA & Mopra Priority Science Star Formation; 2.Understanding the Magnetic Universe; 3.Understanding the Variable Sky; 4.Interstellar Gas In and Around the Milky Way and Nearby Galaxies; 5.The Evolution of Galaxies at High Redshift. CSIRO - ATNF: Science Priorities

6 Parkes Priority Science Pulsar science (timing and searching); 2.Surveys for Diffuse emission; 3.Star formation studies.

7 CSIRO - ATNF: Science Priorities LBA Priority Science 2010 – The structure of our Galaxy; 2.Local Group proper motions; 3.Understanding the variable sky; 4.Megamaser cosmology; 5.Jet motions; 6.Pulsar proper motions and parallaxes.

8 CSIRO - ATNF: Science Priorities Complimentary Capabilities Galaxy formation and gas evolution in the nearby universe ASKAP will survey large numbers of HI galaxies in the nearby universe to understand galaxy formation and evolution to z<1. Parkes will provide the extremely large-scale context of diffuse intergalactic material between galaxies, and crucial large-scale information for combination with ATCA interferometric data. ATCA will provide context of galaxy formation and gas evolution from diffuse interstellar mapping of the Milky Way and nearby galaxies, extended disks, intergalactic gas.

9 CSIRO - ATNF: Science Priorities Complimentary Capabilities Pulsar science Parkes will conduct large area surveys and undertake regular high precision timing of millisecond pulsars and general timing on regular pulsars. LBA will provide information on proper motions and distances. ASKAP will ultimately provide precision timing and a wide-field survey capability once the technical and computing challenges are overcome. ATCA and Mopra are not expected to have major roles in pulsar science.

10 CSIRO - ATNF: Science Priorities Complimentary Capabilities Star formation ATCA will provide detailed studies of star forming regions and the dense interstellar gas in the centimetre, 12-mm and 7-mm bands. Mopra will specialise in large surveys at 3, 7, & 12 mm to be used for defining ATCA and ALMA samples. Mopra will also provide the large-scale interstellar medium context through millimetre surveys that make use of its large bandwidth. Parkes will probe star formation processes through studies of masers. LBA studies of maser internal motions will probe the evolution of star formation. ASKAP is not expected to have a significant role in Galactic star formation studies.

11 CSIRO - ATNF: Science Priorities Complimentary Capabilities Galaxy evolution and population studies across cosmic time ASKAP will measure population statistics of AGN and star-forming galaxies through deep, confusion limited all-sky surveys at 1.4 GHz. ATCA will be crucial in measuring the spectral energy distribution of AGN and star-forming galaxies between 1 and 50 GHz. Parkes and Mopra are not expected to have significant roles in this science area.

12 CSIRO - ATNF: Science Priorities Complimentary Capabilities Magnetic fields through cosmic time ASKAP will create a grid of rotation measures across the sky to understand the origin of cosmic magnetic fields. ATCA will study the diffuse, line-of-sight resolved magneto-ionic medium in the Milky Way and nearby galaxies through broadband spectro-polarimetric observations. Parkes will provide essential zero spacing diffuse polarization surveys in the 1-10 GHz range for combination with ATCA and ASKAP data. Mopra and the LBA are not expected to have a significant role in this science area.

13 CSIRO - ATNF: Science Priorities Complimentary Capabilities Understanding the variable sky ASKAP will monitor the entire sky everyday – a unique capability for detecting transients and monitoring variable sources. ATCA will provide multi-frequency follow-up of ASKAP/MWA transients. LBA will provide high angular resolution follow-up to ASKAP/MWA transients. Parkes has the capability to find very fast transients as part of its major pulsar surveys. Mopra is not expected to have a significant role in this area.

14 CSIRO - ATNF: Science Priorities Complimentary Capabilities Breakdown of facilities by science area. The circle size indicates the priority/impact of a given facility in an area.

15 Potential New Developments 2010 – 2015 Some possible upgrades that could be costed and then put to ATUC for prioritsation Extend ATCA N-S baselines to ~400m Shift 6 km ATCA antenna to 3 km track FPA or MB receivers on Mopra for 3, 7, 12mm 12mm FPAs for ATCA 12mm FPA or MB for Parkes ( Enhance ASKAP configs. and/or N ANT )* ( Extend ASKAP freq. coverage )* New community ideas! * Would require major (international) resourcing CSIRO - ATNF: Science Priorities
