Explore how baryonic matter influences cosmic structure formation through advanced computational simulations in this 46-minute conference talk by Joop Schaye from Leiden Observatory. Delve into the complex interactions between ordinary matter and dark matter that shape the large-scale structure of the universe, examining how gas dynamics, star formation, and feedback processes affect cosmological observations. Learn about cutting-edge simulation techniques used to model these baryonic effects and their implications for interpreting data from large-scale surveys across multiple wavelengths. Discover how these simulations help bridge the gap between theoretical predictions and observational data in modern cosmology, particularly in the context of cosmic microwave background studies, galaxy clustering analysis, and gravitational lensing measurements. Gain insights into the challenges of accurately modeling baryonic physics and understand how these effects must be accounted for in precision cosmology studies that combine multiple observational probes to advance our understanding of the universe's structure and evolution.
