Join group to receive calendar invite: https://groups.google.com/a/modelingt... Abstract: About 14 billion years ago there were no galaxies. Since that time, the universe has expanded enormously, and a cosmic web of galaxies has developed. How did this happen? Why do galaxies exist in so many sizes and shapes? How do they regulate their growth? Questions like these cannot be answered using laboratory experiments, and the formation of galaxies proceeds too slowly to observe in real time. Computer simulations therefore play an important role in the interpretation of observations. I will discuss how simulations contribute to our understanding of the evolution of galaxies and the large-scale distribution of matter in the universe. Bio: After obtaining his PhD from Cambridge University, Joop Schaye spent 4 years at the Institute for Advanced Study in Princeton as a long-term member before taking up a faculty position at Leiden University in 2005. Schaye works on simulations and observations of galaxies, the intergalactic medium, and large-scale structure. He has led influential, international simulation projects such as OWLS, EAGLE, FLAMINGO, and COLIBRE. Schaye was awarded the 2010 Pastoor Schmeits prize and the 2022 Royal Astronomical Society Group Award (to the EAGLE team led by him). He is a member of the Royal Netherlands Academy of Arts and Sciences (KNAW). #modeling #simulation #ai #ml #research #universe #cosmology #cosmic #bigbang #galaxies
