The impact of galactic structure on star formation

这个项目调查了星系结构在决定星系如何从其内部气体形成恒星方面的作用。对三个附近的螺旋星系进行了模拟，发现它们的演化过程非常相似，尽管它们的旋转速度、恒星和暗物质的分布都不同。不过，也发现了一些较小的差异，比如气体随半径的消耗速度有多快，这将是许多论文（正在准备中）的主题。这些星系是更大的BESPOKE（已知例子上更好的河外模拟物理）国际合作项目的第一个组成部分，该项目将探索更广泛的目标和物理学的广度。初始条件也将在不久的将来公开，供其他研究人员使用。不幸的是，首席研究员搬到了海外的一个研究所，所以计划的三年只进行了第一年的工作，但他们将在搬迁后继续与日本和海外的研究人员合作。

This project investigated the role of galactic structure in determining how a galaxy can form stars from its gas within. Simulations were performed of three nearby spiral galaxies and were found to be remarkably similar in their evolution, despite their different rotational rates and distribution of stars and dark matter. Some smaller differences were found though, such as how rapidly gas is depleted with radius, which will be the subject of a number of in papers (in preparation). These galaxies are the first building blocks of the larger BESPOKE (Better Extragalactic Simulation Physics on Known Examples) international collaborative project, which will explore a wider range of targets and breadth of physics. The initial conditions will also be made publicly available in the near future for the use of other researchers. Unfortunately the principal investigator moved to an institute overseas so only the first year of work out of the planned three was conducted, but they will pick up this work upon relocation with continued collaboration with researchers in Japan and overseas.
