Astronomy

Since the beginning of modern astronomy, the scientific community has expressed great interest in scientific visualization tools. Astronomy is renowned not only for its beautiful 2-dimensional pictures, but also for the huge amounts of data it generates. This data can be so complex that a third dimension - as offered in our Reality Cube - is needed to understand it. People have 'discovered' interesting features in their data in the Reality Cube, features they hadn't seen while using their desktop computers.

Cosmic Web

The interior of the universe is permeated by a tenuous space-filling frothy network. Welded into a distinctive foamy pattern, galaxies accumulate in walls, filaments and dense compact clusters surrounding large near-void areas. Using redshift data from the Sloan Digital Sky Survey, R. van de Weygaert studied the clustering of galaxies and identified the location of filaments and examined the results in our Reality Cube.

Colliding Galaxies

The Canadian astronomer John Dubinski has simulated a possible collision between our own Milky Way and the nearby Andromeda Galaxy, and created some strikingly beautiful 2D movies from the data. Of course those collisions can be better studied in our Reality Cube, with the real-time interactive viewer that has been created for this purpose.  The data can now be studied floating in mid-air, by walking around it and observing the collision from all angles. »

While conducting his PhD research at the Kapteyn Astronomical Institute, Rense Boomsma did some very sensitive observations of the face-on galaxy NGC 6946. He found high velocity H clouds and some evidence for recent gas accretion.

Morphology of large-scale structure

M. Aragón Calvo has been working at the Kapteyn Astronomical Institute on the morphology of the large-scale structure of the universe. He has created some multiscale filters that can sort the structures into elongated, spherical and planar. He uses the Reality Cube to compare different filters and different parameters. The filters produce values of blobness, filemanteriness and wallness, which are used te determine the colour of the galaxies.
