  • What is PULSE@Parkes? - BackgroundASKAP Budget Announcement, 8 May 2007:As part of the project, CSIRO will extend its annual in-service training for around 200 high school teachers through the provision of Year 11/12 maths and physics education material involving data and information from the ASKAP. This will expose the next generation to world-class science and technology in a unique way.

    Where to start?

  • ChallengeNeed to develop and implement stimulating, engaging, and worthwhile radio astronomy activities appropriate for high school studentsDevelop educational pedagogy and technical systems for school use of ASKAP data

  • The Project TeamCoordinator & education leader: Robert HollowScience leader: George Hobbs

    Other ATNF staff: David Champion, Jessica Chapman, Mary Mulcahy, Shaun AmySummer Vacation Program student: Matt CarrCSIRO ICT Centre input: Leila Alem, Laurie Wilson, John Zic, Alex Krum-HellerSwinburne: Sarah Burke, Willem van StratenLink with: Rick Jenet (UTB)

    Possible future link with David McKinnon & Lena Danaia (Charles Sturt University, Bathurst)

  • What are we trying to do?High school students observe pulsars using the Parkes radio telescope Obtain observations with educational value for the students and scientific value for the astronomical communityDemonstrate and develop remote observing capabilities at ParkesPromote the ATNF telescopes and extend outreach with the ATNF facilitiesDevelop a sequence of educational programs for the ASKAP era

    Project inspired by Rick Jenets ARCC project at UTB

  • Program DevelopmentPhase 1: Oct 07 Feb 08Develop conceptApply for telescope timeIdentify and work with two test schoolsWrite project materialsTrial & refine proceduresPhase 2: Feb 08 - ?Apply for more telescope timeOpen up project to more schoolsBuild up data archiveFoster collaboration across schoolsDevelop more activities and modify existing material as requiredPhase 3: 2008 Develop new observing projects

  • School SelectionTwo schools for initial trialNSW Government High Schools:Kingswood High SchoolMuswellbrook High SchoolSelection through:teacher interest from ATNF Teacher Workshopsdiscussion with STANSW early mentoring programTarget group Year 11 (10-12)Need to decide future criteria for observing slotsSchools may be non-observers and just use data and activities

  • First StageSuccessful gaining telescope time: P595; 8 hoursTrialled remote observation setup from Marsfield in OctoberSelected 34 pulsars for projectTwo schools selectedSVP selected to work on project materials over summerFirst school visit and trial completed observations on 4 December!Second school trial on 13 February 2008Project materials under development

  • Why Pulsars?Existing model of student engagement (ARCC)Local expertise & interestSingle dish astronomy conceptually easier for studentsPossible to get time on ParkesShort observations produce useful data for concise activitiesData is useful for other projectsCan link in with existing observational programs (PPTA, GLAST) & ARCC

  • Selection of pulsarsPulsars have been chosen so that:1. Each observation only lasts between 2 and 15 minutes2. Have enough pulsars to be observed at any sidereal time3. Are useful for long-term timing programs4. Provide interesting, small experiments for the students to carry out

    Selected from:The GLAST timing project (i.e. young, pulsars that show timing irregularities)Millisecond pulsar timing (our sample includes J1713+0747, J2145-0750, J2317+1439)Pulsars with oscillatory timing noise on long time scales (e.g. B1828-11)

  • Before an observing sessionStudents work through online materials and background readingVisit the school to talk on the projectExplain about pulsars, radio telescopes and observingHelp the students determine which pulsars they will be able to observeLet the students do some basic processing using existing data sets

    Insert presentation title, do not remove CSIRO from start of footer

  • A typical observing sessionThe students will arrive at the ATNF lecture theatre (Marsfield)Introductory talk and a short movie describing the projectIntroduce the students to the Parkes astronomer Parkes by video conferencingStudents then work through checklist to check if observations can proceed, eg check the weather via the winds monitorShow movie of unstowing the dishOnce observing the students will - view webcams of the telescope and control room - be able to control the telescope using VNC - monitor the data in real time (using a website) - chat with the controller at Parkes - monitor the weather displays - hear the pulsar sounds recorded by the telescopeStart initial processing of the data
