Summary of activities June 2015 - August 2015

WP1 - Management

  • Second GENUS trimestral telecon on 18 of June 2015.

WP2 - User community

  • 06/2015 Marese (ASDC) provided a LL document on the planned WP240 Seamless data retrieval across archives and wavelength domains
  • 06/2015 Michele Fabrizio selected for WP240 1 yr contract at ASDC will begin in july 2015
  • 06/2015 ASDC organized a workshop on cross-matching in different wavelength domain, from gamma-ray to FIR.
  • 06/2015 Solano put Marese and Francois-Xavier Pineau of FP7 Arches in contact - someone from Genius will attend the Arches end of program conference in Paris
  • Costigan has lead the development of ideas for the simple archive interface, through telecons (15th June) and wiki enteries ( She has also been in contact with a number of amateur groups to gain ideas as to how they expect to interact with the Gaia archive.
  • Costigan has worked on estabilishing Beta testing alongside with N. Hambley and G. Garcia. This mainly included a detailed review the use case scenarios (AB-026), their implementation status, and possibility of testing with the current data sets available. This has been written up (GCO-002) and is awaiting further review from other parties.
  • Costigan has investigated and written up ideas for the Living Archive aspect of the Gaia archive (GCO-003).
  • Costigan tool part in the CU9 Plenary meeting in Barcelona, where she presented the document on the Living archive to the Archetecture splinter, as well as those issues brought up in GCO-002. Costigan also presented those requirements gather from amateur user groups for the development of the simple archive interface.
  • Hypki finished a draft document on the project deliverables for WP2 T2.3 "Confronting complex models with complex catalogues - User Requirements Specification"
  • Hypki finished a draft document on the project deliverables for WP2 T2.3 "Confronting complex models with complex catalogues - Technical Specification"
  • Hypki took part in the CU9 plenary meeting in Barcelona, 21-23 September 2015. He verified with other CU9 members the technical feasibility of the proposed advanced requirements specified in the deliverable T2.3
  • YY invited Prof. F. Mignard (OCA) and Prof. G. Gilmore (IoA) to the summer school of distance ladder by using EU-FP7 money. ( Number of participants are 71, from 19 countries. They are the potential users of Gaia data. FM and GG had lectures. In these lectures, characteristics of Gaia data and its possible science topics are introduced. These lectures are useful for potential users of Gaia data. Audiences understood how and what purpose the astrometric data will be used. JASMINE member have discussion with FM on Nano-JASMINE data analysis (YY went to Tokyo for organizing/attending the discussion meeting). Kye of the Nano-JASMINE data analyis will be the accuracy of attitude reconstruction. In Gaia observations, number of stars on the same focal plane will be large. Attitude will be reconstructed easily. On the other hand in Nano-JASMINE, attitude reconstruction will be hard problem like the case of Hipparcos. Also JASMINE member have discussion with GG on possible collaboration of post-Gaia and Japan astrometry community. Infrared astrometry technique will be the candidate of post-Gaia collaboration with Japan. Viewgraphs of FM and GG will be here. Please ask file read password to YY. Sorry, I cannot remove password.

Once the Editorial Board gave the OK to the portal design, further steps have been done:

  • Gaiaverse's mobile optimization.
  • Mozilla, Chrome and Internet Explorer optimization as to achieve better performance.
  • Introduction of multilingual contents and revision of the previous ones according to the comments submitted by the Editorial Board.
A Gaiaverse's Twitter account has been created, whose objective is to reinforce the portal dissemination around and establish users engagement from the very beginning. This Gaiaverse account will complement the GENIUS project account.

Gaiaverse has been launched in July 8th.

T7.3 - Community portal, outreach and academic activities
