Cosmological Simulations of Galaxy Formation

Understand

Over the last decades, cosmological simulations of galaxy formation have been instrumental for advancing our understanding of structure and galaxy formation in the Universe.

• These simulations follow the non-linear evolution of galaxies modeling a variety of physical processes over an enormous range of scales.
• A better understanding of the physics relevant for shaping galaxies, improved numerical methods, and increased computing power have led to simulations that can reproduce a large number of observed galaxy properties.
• Modern simulations model dark matter, dark energy, and ordinary matter in an expanding space-time starting from well-defined initial conditions.
