Presentation Transcript

  1. ARC node at IRAMF.Gueth – IRAM Grenoble IRAM Interferometry School

  2. ALMA @ IRAM • IRAM deeply involved in ALMA construction • Hardware: • band 7 (280—360 GHz) development and (pre-)production • receiver common optics • backend samplers • Software & proto-ARC: • scientific software requirements (SSR) group • real-time telescope calibration pipeline • tests of prototype antennas IRAM Interferometry School

  3. Band 7, Lazareff et al. IRAM

  4. Band 7 noise temperature, 8 GHz IF (Maier et al. IRAM)

  5. ARC node at IRAM • IRAM partners • CNRS (France) • MPG (Germany) • IGN (Spain) • ARC node at IRAM also supported by • French community • Spain ALMA committee • IRAM open to all astronomers: 30% observing time outside partner countries, TNA RadioNet FP6 IRAM Interferometry School

  6. IRAM millimeter interferometry center • IRAM ARC node will be an activity of the IRAM millimeter interferometry center • Center is already in place • GILDAS software (CLASS, CLIC, …) • PdBI f2f user support since >10 years • mm-interferometry school series since 1998 • general expertise in mm-interferometry calibration and imaging techniques IRAM Interferometry School

  7. ARC node at IRAM • Goals of mm-interferometry expertise center: • User formation • User face-to-facesupport • Technical expertise center • Data reductionsoftware • Based on and fully open to collaborations with other groups • Several actions already started or planned IRAM Interferometry School

  8. User formation • Interferometry school series  5th school Oct. 2-6 2006, 66 participants • Long-period visits of PhD/postdocs • Formation to mm-interferometry techniques and data reduction, observations at PdBI (new access) • Can start in 2007 (new building available) • Please contact us if interested IRAM Interferometry School

  9. IRAM mm-interferometry school series • Every two years since 1998 • General introduction to mm-interferometry, PdBI data reduction, introduction to ALMA • ALMA practical session in 2008 ( Early Science) • Lectures and book available on the web

  10. User f2f support • In place at IRAM for PdBI since ~10 years • Each project has a local contact to help during the data reduction at Grenoble • Will be extended to support ALMA users • Critical for early-science  required in 2009 IRAM Interferometry School

  11. Technical Expertise • ALMA commissioning • GILDAS to be used for antenna SD holographies • New observing mode: OTF interferometry development at PdBI then ALMA (EU-FP6) • Using Jupiter satellites as mm flux calibrators: PdBI/30m project started (collab. with Paris Obs.) • ALMA imaging simulator IRAM Interferometry School

  12. Software devl’t • Software developments for ALMA: • telescope calibration pipeline • GILDAS/CLIC adapted for ALMA holographies • goal: long-term support/upgrade of ALMA software • pyGILDAS development: interoperability of the data reduction software (collab. with Bordeaux Obs.) IRAM Interferometry School
