走向现实主义银河系的形成

Toward the Formation of Realistic Galaxy Disks

Alyson Brooks

摘要:

在这篇评论中,我证明了一个现实的模型,星系盘的形成取决于一个适当的治疗星系中的气体。从历史上看,盘状星系形成的宇宙学模拟一直缺乏分辨率和物理激励的反馈处方。最近的计算进步已经允许前所未有的分辨率,这反过来又允许更现实的处理反馈。这些进展导致了一个新的检查气体吸积,演化和损失的星系盘的形成。在这里,我强调的作用,气体流入,气体的反馈调节,气体流出发挥在实现模拟盘星系,更好地匹配观测结果作为红移的函数。

英文摘要:

In this review I demonstrate that a realistic model for the formation of galaxy disks depends on a proper treatment of the gas in galaxies. Historically, cosmological simulations of disk galaxy formation have suffered from a lack of resolution and a physically motivated feedback prescription. Recent computational progress has allowed for unprecedented resolution, which in turn allows for a more realistic treatment of feedback. These advances have led to a new examination of gas accretion, evolution, and loss in the formation of galaxy disks. Here I highlight the role that gas inflows, the regulation of gas by feedback, and gas outflows play in achieving simulated disk galaxies that better match observational results as a function of redshift.
