The nexus between kinematic complexity and black holes in star clusters

该研究方案旨在调查碰撞恒星系统，特别是星星星团中“运动学复杂性”与黑洞之间联系的物理起源。这些活动分为三个主要阶段：（i）形成，（ii）平衡，（iii）演化，在（i）阶段，我推进了“运动复杂性”在星星团动力学中作用的理论研究。已向同行评审期刊提交了两篇文章，不久还将提交另外两篇论文。这些手稿是与爱丁堡大学的研究人员合作编写的。另外两篇关于以前开始的项目的文章也被接受出版。在第二阶段，我已经开始构建一个中心黑洞的平衡动力学模型，我在分析盖亚数据发布2的观测数据方面取得了良好的进展。目前正在撰写论文，并将尽快提交。第三阶段预计在2年级进行，因此还没有开始。在奖学金中断后（由于在爱丁堡大学的新工作），我在东京大学担任了6个月的客座研究员。今后，我将继续与藤井教授在第（iii）阶段以及我们与东京大学系研究人员合作开展的其他项目上合作。在科比的物理和理研。

This programme of research is aimed at investigating the physical origin of the nexus between‘kinematic complexity’and black holes in collisional stellar systems, especially star clusters. The activities were structured in three main phases: (i) formation, (ii) equilibrium, (iii) evolution.On phase (i), I have pushed forward the theoretical investigation of the role of 'kinematic complexity' in the dynamics of star clusters. Two articles have been submitted to peer-reviewed journals and two additional papers will be submitted shortly. These manuscripts have been prepared in collaboration with researchers at Univ. Edinburgh. Two additional articles on previously started projects have also been accepted for publications.On phase (ii), I have started the construction of equilibrium dynamical models with a central black hole and I have made good progress in the analysis of the observational data from Gaia Data Release 2. A manuscript describing this study is currently in preparation and will be submitted soon.Phase (iii) was expected to take place in Year 2, therefore has not started yet.After the Fellowship interruption (due to new employment at Univ. Edinburgh), I have been based at UTokyo as a Visiting Associate for six months. In the future, I will continue to collaborate with Prof Fujii on phase (iii) and on other projects which we have already initiated in collaboration with researchers at the UTokyo Dept. of Physics and RIKEN in Kobe.
