A tOoL for stereographiC visuAlization and analysis Of astrophySical data

Objective

We will develop a visualization tool for astrophysical problems using the most innovative techniques of virtual reality and advanced 3D visualization. A prototype (AstroMD) is available (developed at Cineca and the Astrophysical Observatory of Catania). Our project extends the AstroMD capabilities to respond to the requirements proposed by several research fields for the management and the analysis of data coming from: cosmological simulations, galaxy catalogues, radio sources. In addition, new methodologies for education and diffusion of astrophysical culture will be developed. The tool will be portable on several platforms: virtual theatres, immersive desks, workstation or personal computers with the software for a 3D stereo-graphic visualization.

Objectives:
Our objectives are the development of the most modern visualisation techniques for astrophysics, education and the improvement of our knowledge of the Universe through the application of these technologies to three specific fields in astrophysics. We also want to promote new, easier and more intuitive methodologies of learning both for specialists and for students at several degrees. The virtual reality and the techniques of advanced 3D visualisation are particularly suitable for astrophysics; a field in which the objects we observe are projected onto the celestial sphere and generally have an asymmetric morphology. The possibility of visualise the three-dimensional structure of the astronomical objects permits the recognising of their peculiarities and characteristics. Moreover the more intuitive approach to complex concepts of astrophysics, offered by the techniques that we want develop, will extend the astrophysical knowledge on a larger community both of specialists and non.

Work description:
The capabilities of AstroMD will be extended in order to respond to the requirement of the astrophysical problems we want to face and to that of education as summarised below: Cosmological simulations: The available prototype of AstroMD will be implemented with functionalities for the calculation of quantities of cosmological interest as the correlation function, the gravitational field, the power spectrum. The most common data format used in cosmological simulation (e.g. TIPSY format) will be implemented. Volume rendering techniques will be integrated to visualise volumes with different levels of transparency. Visualisation of galaxy catalogues: we intend to refer to the catalogues compiled in the ambit of the Virmos, a consortium of six astronomical Institutes in Italy and France. Specific tool for the individuation of the objects and the description of their characteristics will be implemented together with the possibility of extracting and visualising sub-samples of data according to their nature and physical characteristics. Powerful radio-sources: According to the dynamical and emission models of radio sources developed by the Institutes of radio astronomy of Bologna and Oxford, new functionalities will be implemented in AstroMD with the aim of represent the directional emission from the radio sources and integrate it along the line of sight to compare the model with the available observations. Education: A tool specifically oriented to didactics will be developed. It will be characterised by a particularly user-friendly interface and by a set of functionalities explaining the characteristic of the visualised data and an accurate description of the physical processes related. The tool will implement also functionalities with the aim of testing the correct understanding of the concepts explained. A route of learning will be projected in collaboration with the schools, taking advantage of the past experience of the Institute of radio astronomy of Bologna.

Milestones:
We intend to achieve an exhaustive and clear project presentation within the end of the month 2. We also intend to produce a public progress report each six months. The beginning of application workpackages is at the beginning of month 2 and the specifications definitions and the software pilot 1 are expected at the end of month 12.The final results and the final tool of visualisation will be published at month 24.
