An “All digital Science”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.
That is : ready for the Grid !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!)
First steps for the GridFirst 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
Applications: Case study IApplications: Case study IDatabase and Astrophysical Archives

VST is a 2 m. Telescope with a 32.000 x CCD

Data Processing for ESA/PlanckData 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)
La scelta per la La scelta per la rimodulazionerimodulazione
“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 Griddelle applicazioni astrofisiche.
Di conseguenza abbiamo bisogno di una, per quanto limitatastruttura di Grid funzionante di cui “non occuparsi”

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.

Observing the heavenly bodies at radio frequency
1) Identificazione di sorgenti da archivio TNG
2) Selezione di osservazioni “particolari” da archivio TNG
Cosa si e’ fatto finoraCosa si e’ fatto finora
La situazione INAF e’ molto grave dal punto di vista finanziario e questo e’ un grosso problema

Preparazione dati e sistemi per inserimenti in esperimento : TNG a Trieste, GSCII a Padova
