The impact of galactic structure on star formation

该项目研究了星系结构在确定星系如何从其内部气体形成恒星方面的作用。对附近的三个螺旋星系进行了模拟，发现它们的演化非常相似，尽管它们的旋转速率和恒星和暗物质的分布不同。不过，也发现了一些较小的差异，例如气体随着半径的增加而耗尽的速度，这将是许多论文的主题。这些星系是更大的BESPOKE（已知例子的更好的河外模拟物理学）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。初步条件也将在不久的将来公布，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，所以计划中的三个研究所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开展这项工作。

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.
