A Method to Determine the Largest True Structures in the Universe
Suketu P. Bhavsar
University of Kentucky
The large scale distribution of galaxies in the universe is a 3-D lacework of filaments and voids. The size of the largest features and the scale on which the universe is homogeneous is an extremely important datum for Cosmology. The determination of this scale is complicated by the fact that unraveling physical structure from visual features is a very difficult task. This talk will present results of determining the extent of the longest true filamentary features from a red-shift survey. This result is the product of a statistical technique that itself has become an important tool in astronomy. This method, called 'shuffle', will be described and demonstrated.
Refreshments at 4:00 PM. Seminar begins at 4:10 PM.
