GAVO• GAVO is a project, sponsored by the BMBF, for building a "Virtual

Observatory" platform to support modern astronomical research in Germany. It is the German contribution to the international activities aiming at the creation of a global Virtual Observatory (VO) network.

• Status GAVO II• Review GAVO I

– archives– data mining– grid– theory

• Role in DCA

GAVO activities

• MPE/A Archives:– ROSAT– Sloan SkyServer Mirror (soon DR5) and peripherals

(indices, MOPED, PCA)– Millennium databases (MyDB)– All-sky maps (HEALPix) : ROSAT, WMAP, Planck

• Other archives– Heidelberg: various (Hipparcos etc)– Potsdam: RAVE

• Datacenter ARI-ZAH– Host small datasets of individual astronomers.– Collaboration with CDS ?

GAVO activities cntd.

• DAL: – SCS on ROSAT photons and source catalogues– SIAP on ROSAT pointed observations (based on FITS keyword metadata repository in

SQLServer)– SSA prototype on CDFS optical spectra, MPE-based XMM-results planned

• VOQL– Cross-matcher (upload list+VizieR+SDSS, two recent publications, Komossa et al)– Technische Universität München-Informatik: StarGlobe, HisBase (with JHU)

• Data mining services– ClassX – SED classifier

• Access tools– web browser– Java GUI– adapters for accessing database remotely: Perl+SOAP,TOPCAT, IDL, R

• Theory– Virgo consortium’s Millennium database (MPA, Durham; astro-ph/0608019) – Various virtual telescopes (Planck, MoMaF, X-Ray)– IVOA

• D-Grid/AstroGrid-D– cluster finder– virtual telescopes– distributed matching

Participation in WPs

• WP2: Definition of European Strategy– Census in Germany (datacenters AND services)– X-Ray requirements and specs– Theory strategy

• WP3: Support to take-up and implementation of VObs Framework (in GAVO)– Existing archives in Germany (within GAVO and outside), e.g. digitised plate archives– new: E-ROSITA preparation, PanStars, Planck

• WP4: Theory in the VObs (next slide)– Collaborating on creation of standards – Managing of various theory archives and services– Create reference implementations of theory standards – Hosting workshop(s)

• WP5: Coordination with computational grid projects– MPG/GAVO Participant in D-Grid’s AstroGrid-D– implementation theory services (virtual telescopes, cutout Millennium simulation for

SNAP)• WP6: Support to data centers from other European countries

IVOA Theory Interest Group• Motivation• Horizontal• TWiki/mailing list• Use cases• SNAP

– objects existing/evolving in 3D space– DAL++ like– subvolume extraction

• Semantics/UCD– simulation parameters– physics– source code

• Data model– provenance– subject/physics– characterisation

e.g.• dal

– ESO: ROSAT metadata repository

• dm – characterisation for simulations

• theory (already started)– SNAP– semantics– MoMaF
