Visualization

Data visualization

In the new Big Data era, research faces the enormous challenge of discriminate, analyse, and present data of unprecedented complexity and volume. In particular, the multi-dimension nature of the ORION-4D represents a challenge for traditional analysis techniques. As part of this project, we will explore new visualization schemes for scientific purposes. Our goal is to facilitate both the analysis and interpretation of these data based on free-software tools.

I.- Movies

Content: Movie showing the resolution effects on the study of filaments. The image shows the ALMA + IRAM30m data at the native resolution of the ALMA-12m array (4.5"), in comparison with the simulated ACA (10-20") and single-dish (>25") resolutions. Note how the internal structure of this filament is already smeared out and lost at the resolution of ACA and single-dish observations. This comparison illustrates the need of the ALMA-12m data (at resolutions <0.01pc) on the study of massive clouds like the Orion Integral Shape Filament.

III.- Interactive plots

Content: Gas vs. stellar motions, in Position-Position-Velocity (PPV) space (X,Y,Z), in the Orion A cloud. Symbols: VLSR velocities for the APOGEE (black solid points) and APOGEE-YSO (red solid points) stars. Contours: Iso-densities of stars (red and blue surfaces) and CO gas (yellow and green) within the same region (see also).
