The Bristol Astrophysics Group has concentrated its research on the origins, growth, and structure of the largest-scale objects in the Universe: galaxies and clusters of galaxies. The Group conducts surveys using radio, infra-red, optical, and X-ray telescopes to search for young galaxies and clusters at high redshift - which means that the objects are both very distant in the Universe, and are being seen a long time in the past, when they were young. Studies of these young objects should then show more evidence of how they formed than studies of galaxies and clusters closer to us (and hence older). The question of how the younger objects develop into the clusters and galaxies that we see today is also important, and here it appears that much complicated physics to do with gas flows, galaxy and cluster collisions, and the energy release from black holes is relevant. Sometimes rare events, such as outbursts from so-called 'active' galaxies or major collisions, change the properties of the galaxies and clusters dramatically. In between these events, slower processes allow the galaxies and clusters to settle back towards an almost-steady, but ultimately unstable, state. Since the physics is complicated, we are engaged in many projects aiming to disentangle the problems and understand what processes are most important, and what are their consequences. Because the Bristol Astrophysics Group is small, it is important that it works closely with its collaborators to study these complicated problems. Visitors to the Group are, therefore, of great importance to the research of the Group, and this proposal requests funding to bring collaborators to Bristol to work with Group members. At the same time, this helps to extend the range of astrophysics to which Group research students and post-doctoral research fellows are exposed, and transfers ideas to our collaborators' institutions.

布里斯托尔天体物理学小组集中研究宇宙中最大规模的天体：星系和星系团的起源、增长和结构。该小组使用射电、红外线、光学和X射线望远镜进行调查，以寻找高红移的年轻星系和星系团-这意味着这些物体在宇宙中都非常遥远，而且在过去很长一段时间里，当它们还很年轻的时候，人们就可以看到它们。对这些年轻天体的研究应该比对离我们更近的星系和星系团(因此更古老)的研究显示出更多关于它们是如何形成的证据。年轻的天体如何发展成我们今天看到的星系团和星系的问题也很重要，这里看起来与气流、星系和星系团碰撞有关的复杂物理学，以及黑洞释放的能量是相关的。有时罕见的事件，如所谓的“活跃”星系爆发或大碰撞，会极大地改变星系和星系团的性质。在这些事件之间，较慢的过程允许星系和星系团回到几乎稳定但最终不稳定的状态。由于物理学很复杂，我们参与了许多项目，旨在理清问题，了解哪些过程最重要，以及它们的后果是什么。由于布里斯托尔天体物理学小组规模很小，与其合作者密切合作研究这些复杂的问题是很重要的。因此，访问小组的来访者对小组的研究非常重要，这项提议要求提供资金，以便将合作者带到布里斯托尔与小组成员一起工作。同时，这有助于扩大团队研究学生和博士后研究员接触的天体物理学的范围，并将想法传递给我们的合作者的机构。
