银河系数值模拟研究现状
Progress on Numerical Simulation of the Milky Way
摘要
Abstract
The standard cosmological model has become one of the most successful frame-works for explaining and predicting the formation and evolution of large-scale structures.Over the past few decades,numerical simulations based on the standard cosmological model have deepened our understanding of cosmic structures and galaxy formation,serving as a bridge between theoretical research and observational data.The Milky Way,as the most familiar and extensively observed galaxy,provides valuable samples for studying the galaxy formation and evolution.The article reviews the current status of numerical simulations of the Milky Way over the past decade.First,it introduces the cosmological background of large-scale structures and the numerical techniques of N-body simulations.It then discusses theoretical models of galaxy formation and methods of hydrodynamics simulations,detailing the impact of baryonic physics mechanisms on galaxy evolution and the numerical subgrid models.Subsequently,it focuses on zoom-in techniques for simulating the Milky Way and some popular Milky Way simulation projects,as well as the latest progress in using Milky Way simulations to study small-scale issues.Finally,the article concludes with a summary and outlook on the future of Milky Way simulations.关键词
