WKYC 2011 - Future of Large Scale Structure Formation

June 27th - July 1st (KIAS rm 1114)

Designed by Soo Yeon Jeong

Purpose of meeting

The next generation of cosmological observations will be launched to scan inhomogeneity at large scales, such as SDSS3, DES, EUCLID and LSST. These experiments be optimally designed to answer the question whether our understanding of nature on the earth is universal or not. We plan to discuss signatures of our fundamental knowledge of physics imprinted on large scale structure formation of the Universe, different approaches to falsify either dark materials or violation of fundamental laws, and computational and observational techniques to extract physical knowledge from raw data. We are at a critical moment of understanding of Nature, and we need inter-communicating leadership between theoretical knowledge and observational techniques. We will discuss issues to develope research to meet such a need.
