2003/11/27CVO Meeting in Beijing Infrared Satellite by JAXA Launch : 2005 ? JAXA is going to join JVO !!

2003/11/27CVO Meeting in Beijing Data Productivity s Nobeyama Radio ： ~1TB/yr s ： ~20TB/yr s ALMA （ planned ）： ~PB/yr Flood of excellent data (survey data) Digitized & Archived

2003/11/27CVO Meeting in Beijing 10 Gbps

2003/11/27CVO Meeting in Beijing HPC + High Speed NETWORK +GRID Technology → it is possible to federate multi- wavelength-DBs and computing facilities for data analyses → Virtual Observatory

2003/11/27CVO Meeting in Beijing JVO prototype : Ver. 1 s Establish seamless access to federated DBs by using the Grid technology s Define JVO Query Language, and implement its parser s Test environment is in a closed subnet

2003/11/27CVO Meeting in Beijing

2003/11/27CVO Meeting in Beijing Query Files can be stored in a local PC (WS)

2003/11/27CVO Meeting in Beijing Monitor Window: Refreshed automatically in every 15 seconds Dynamical creation of a workflow

2003/11/27CVO Meeting in Beijing Sample Outputs

2003/11/27CVO Meeting in Beijing

2003/11/27CVO Meeting in Beijing JVO Query Language

2003/11/27CVO Meeting in Beijing SkyQL & ADQL s JVOQL has been adopted as one of the basis for SkyQL (standard query language in IVOA) s XML description of SkyQL = ADQL Astronomical Data Query Language

2003/11/27CVO Meeting in Beijing Serious Issue Q) GT2 has too large overhead before starting actual jobs !! They are several seconds. A) For batch jobs, such as database accesses, the overhead could be negligible. However users can never wait for several second for interactive data analyses. Request) Overheads must be < 0.1 seconds excluding the network delays.

2003/11/27CVO Meeting in Beijing Partially solved !! s Introduction of NMI -- authentication module : binary s Analysis of the source codes of GTK2 -- polling interval : 30 sec -> 3 sec s Elapsed time was halved ! But …, still very slow.

2003/11/27CVO Meeting in Beijing Improvement of U.I. Need to know about SQL to use JVOQL → An editor to create JVOQL from GUI Edittable on screen → more flexibility for advanced users

2003/11/27CVO Meeting in Beijing

2003/11/27CVO Meeting in Beijing Search for Gravitational Lenses caused (?) by Cosmic Strings s SXDS data observed by Subaru s Query results were obtained less than 5 min., displaying SEDs s It has been proven that VO can accelerate researches.

2003/11/27CVO Meeting in Beijing Cosmic Strings? s Theoretical origin of the elementary particles which existed (?) at t ~ s ， T ~ GeV s Not a POINT, has its SIZE s Width < m, Length ~ size of the Universe. s Mass of 10km string ~ the Earth

2003/11/27CVO Meeting in Beijing Gravitational Lens s A phenomenon that the space-time is distorted by a huge mass object, and multiple images of another object behind the massive object are observed around it.
