ViaLactea Visual Analytics @ NEANIAS

The ViaLactea Service is aimed at exploiting astrophysical surveys of the Galactic Plane to study the star formation process of the Milky Way. The ViaLactea Visual Analytic (VLVA) tool combines different types of visualization to perform the analysis exploring the correlation between different data, for example 2D intensity images with 3D molecular spectral cubes. All underlying data are managed in the ViaLactea Knowledge Base (VLKB). The VLKB includes 2D and 3D (velocity cubes) surveys, numerical model outputs, point-like and diffuse object catalogues and allows for retrival of all the avaiable datasets as well as cutouts on the positional and/or velocity axis and some merging capabilities on adjacent datasets. The project aims at extending the VLVA tool to access cloud services of NEANIAS to access the data services of the ViaLactea Knowledge Base.
