Kaczmarczik Lecture

Wednesday, October 22, 2014

2:00 PM-3:30 PM

Margaret Geller, PhD, senior scientist, Smithsonian Center for Astrophysics


We live in the first time when it is possible to map the universe. We now know that galaxies like our own Milky Way trace the largest patterns in nature. These patterns, first seen in a slice of the universe in 1986, extend for hundreds of millions of light years. Now with large telescopes, we can trace the evolution of these patterns and compare them with some of the world’s largest computer simulations. A new survey, HectoMAP shows us the patterns in the universe nearly 7 billion years ago. A HectoMAP movie takes us through the data. Comparison of HectoMAP observations with simulations provides new direct tests of our understanding of the evolution of structure in the universe.
