1. ‘LABYRINTH’ 3D Visualisations of the Distribution of Galaxies and Large-Scale Structures Tony Fairall Software by Carl Hultquist and SameshamPerumal Depts. of Astronomy and Computer Science University of Cape Town

2. The data used in this presentation are galaxies with available redshifts less than 7500 km/s, as drawn from the NASA Extragalactic Database, supplemented by 6dF.

3. Galaxies are shown as dots. Data may be viewed from any specified position, looking in any specified direction. Major features/voids labelled.

4. However, distances may be colour coded for red-to blue Chromostereoscopy.

5. Or white-to-blue Chromostereoscopy

6. , With the program running, you can fly around in real time

7. Although this demonstration uses a sequence of still frames

13. From the position of our Local Group, we can look at clusters and large-scale features

14. The Virgo and Coma Clusters

15. The Fornax Cluster

16. The Centaurus and Hydra Clusters

17. Cluster ACO 3627 in the heart of the Great Attractor region

18. The Local Void, leading into the more distant Microscopium Void

19. The southern extension of the Local Supercluster towards Centaurus

20. The Perseus-Pisces Filament

21. Galaxies can also be shown as billboards

22. One can also fly around (as with the Swinburne visualisation)

24. Back to galaxies shown as points

25. But they can also be enclosed in ‘Tully’ bubbles to reveal large-scale structures

26. The transparency of the bubbles can be varied

28. They can even appear solid in white/blue 3D

29. Or red-to-blue Chromostereoscopy

30. 100 1 Large-scale structures are incompletely mapped across the ‘Zone of Avoidance’

31. We shall now fly to the centre of the dataset, via the Microscopium and Local Voids

46. We shall fly to the centre of the data set through the Great (Coma) Wall

62. The Local Supercluster is best seen when only denser large scale structures are shown.
