  1. WP 10 – Applicazioni Astrofisica – stato Leopoldo Benacchio INAF Osservatorio Astronomico di Padova Pisa maggio 03

  2. An “All digital Science” End to End cycle on the network: Observation preparation, Remote observing, Data Reduction and Analysis, Archiving, Data mining (virtual observatories), Modelling (theoretical astronomy), Literature, New ideas for new observation, theory etc.

  3. That is : ready for the Grid ! Network allowed strong communication The Web allowed documentation sharing Is the Grid a change of metaphor ? (sharing the work!)

  4. First steps for the Grid We are working on Astrophysical applications within the framework of the Italian Grid for Science : Grid.it (funded by MIUR: 2003-2006) 3 main poles engaged : Padova Trieste, Napoli 7 poles forecasted for the end of the year Main objective is to determine “astrophysical” requirements for the Grid itself

  5. Applications: Case study I Database and Astrophysical Archives (Planck, TNG, GSCII) Poles Involved Trieste, Padova TNG at Canarias

  6. Applications: Case study II Poles Involved Napoli Padova VST is a 2 m. Telescope with a 32.000 x CCD A “pilot fish” For the 4 VLT giants Image reduction and Analysis of the VST survey

  7. Applications: Case study III Poles Involved Trieste Telescopes and the Grid : to distribute remote observing After grid Before grid

  8. Planck 2007: mapping the microwave Universe

  9. Data Processing for ESA/Planck • Highly distributed environment (9 sites) • Collaborative development – inputs to data processing pipeline coming from over 30 institutes in over a dozen countries, in Europe and North America) • Each of the DPC “Levels” perform well-specified tasks (simulations, handling of telemetry, production of frequency maps, separation of astrophysical components, preparation of final products) • Need to share efficiently data (raw and at different levels of processing), information, documents, procedures, software • Grid technology likely to be used (EU FP6 SSA proposal to support feasibility study)

  10. La scelta per la rimodulazione “Fare” un task in meno o meno (diverso) di ogni task ? Ha vinto la seconda ipotesi : rimodulate le attivita’ (per quanto possibile e’ una attivita’ di ricerca!) WP10 Astrofisica ha come compito di dare in output al progetto triennale I “constraints” (requirements)alla Grid delle applicazioni astrofisiche. Di conseguenza abbiamo bisogno di una, per quanto limitata struttura di Grid funzionante di cui “non occuparsi”

  11. Impieghi denaro-persone Rimodulazione denaro-persone 50% richiesto) all’interno dell’udr Grosso sforzo per il “bene comune” dell’UDR: 2 persone (150.000 euro) : 1 a pd-infn, 1 a Cnaf bo) 1 persona per ogni polo (Padova, Trieste, Napoli) .5 persona a Padova per il WP Questo esaurisce la somma disponibile, considerando missioni, piccolo hardware, spese generali varie.

  12. Casi Studio 1) Identificazione di sorgenti da archivio TNG 2) Selezione di osservazioni “particolari” da archivio TNG Observing the heavenly bodies at radio frequency

  13. Cosa si e’ fatto finora La situazione INAF e’ molto grave dal punto di vista finanziario e questo e’ un grosso problema 1 persona assunta a Padova (c/o infn per utenza wp10) Preparazione dati e sistemi per inserimenti in esperimento : TNG a Trieste, GSCII a Padova
