Cosmology with Large-Scale Structure - Lecture 1

International Centre for Theoretical Sciences via YouTube

Overview

Explore the foundations of large-scale structure (LSS) cosmology in this lecture by John Peacock from the International Centre for Theoretical Sciences. Delve into the statistical approach of Poisson clustering hypothesis, understand the concept of bias in relating mass and light, and examine models for bias including high-peak bias. Learn how to test biased CDM linear power spectrum and analyze projected clustering. Discover the significance of APM angular correlations and their role in weighing the universe. Gain insights into the argument for dark energy using 1990 LSS and CMB data, setting the stage for understanding modern cosmological puzzles like dark matter and dark energy.
