Galaxy Surveys - Lecture 3

Explore a comprehensive lecture on Galaxy Surveys delivered by Shadab Alam as part of the 3rd IAGRG School on Gravitation and Cosmology at the International Centre for Theoretical Sciences. Delve into one of the fundamental observational techniques used in modern cosmology to understand the large-scale structure of the universe. Learn about redshift surveys, their implementation, and how they contribute to estimating crucial cosmological parameters. Gain insights into how galaxy surveys help cosmologists measure the density of dark matter, dark energy, and map the distribution of matter across cosmic scales. Part of a broader two-week intensive program covering cutting-edge topics in theoretical and observational cosmology, this lecture forms a critical component in understanding how observational techniques revolutionize our comprehension of the universe's structure and dynamics.
