• The three-dimensional, immersive visualization <strong>of</strong> :<br />
– redshift <strong>and</strong> distance catalogs from <strong>the</strong> Extragalactic Distance Database<br />
(IFA U. <strong>of</strong> Hawaii, U. <strong>of</strong> Maryl<strong>and</strong> & IPNL/U. Lyon) :<br />
• V8k, a catalog <strong>of</strong> redshifts bounded at 8000 km/s (30124 galaxies)<br />
• Cosmic<strong>flows</strong>-1 distances with<strong>in</strong> 3300 km/s (1797 galaxies)<br />
– reconstruction <strong>of</strong> <strong>the</strong> density field<br />
• corrected to account for grow<strong>in</strong>g <strong>in</strong>completeness with distance<br />
– reconstruction <strong>of</strong> <strong>cosmic</strong> <strong>flows</strong><br />
• based on <strong>the</strong> Wiener Filter analytic method<br />
• with <strong>the</strong> objectives to obta<strong>in</strong> :<br />
– a cosmography <strong>of</strong> <strong>the</strong> Nearby Universe :<br />
• creation <strong>of</strong> maps<br />
• identification <strong>of</strong> <strong>the</strong> most prom<strong>in</strong>ent <strong>structures</strong> : voids, clusters, filaments <strong>and</strong> walls<br />
– a visual analysis <strong>of</strong> <strong>cosmic</strong> <strong>flows</strong> versus <strong>the</strong> cosmography<br />
• identify attractors <strong>and</strong> o<strong>the</strong>r sources <strong>of</strong> bulk motions<br />
• nature <strong>of</strong> <strong>the</strong> Great Attractor
