从KIWICS巡天看星系团中超弥散星系的频率和中心损耗
Reviewing the frequency and central depletion of Ultra-Diffuse Galaxies in galaxy clusters from the KIWICS survey
摘要：
超扩散星系团（UDG）的数量对于限制星系团形成和演化的模型具有重要意义。此外，它们在星团内的分布可能会告诉我们一些关于它们与环境相互作用的信息。在这项工作中，我们以比之前研究更一致的方式重新审视了UDG的丰富性。我们添加新的数据UDG在八个集群从Kapteyn IAC编织INT集群调查（KIWICS），覆盖的质量范围内，只有少数集群已经研究过，并补充这些与汇编的作品在文献中均匀研究UDG的数量和质量之间的关系，他们的主机集群。总的来说，我们发现，UDG $-$集群质量关系的数量的斜率是一致的，当考虑星系群或线性，如果他们被排除在外，是次线性的，但我们认为，最有可能的行为是次线性。当系统地研究到最里面的UDG的投影距离和每个星团的M $_{200}$之间的关系时，我们发现了一些线索，这些线索有利于大质量星团在其中心摧毁UDG的图像。
英文摘要：
The number of Ultra-Diffuse Galaxies (UDGs) in clusters is of significant importance to constrain models of their formation and evolution. Furthermore, their distribution inside clusters may tell us something about their interactions with their environments. In this work we revisit the abundance of UDGs in a more consistent way than in previous studies. We add new data of UDGs in eight clusters from the Kapteyn IAC WEAVE INT Clusters Survey (KIWICS), covering a mass range in which only a few clusters have been studied before, and complement these with a compilation of works in the literature to homogeneously study the relation between the number of UDGs and the mass of their host cluster. Overall, we find that the slope of the number of UDGs$-$cluster mass relation is consistent with being sublinear when considering galaxy groups or linear if they are excluded, but we argue that most likely the behavior is sublinear. When systematically studying the relation between the projected distance to the innermost UDG and M$_{200}$ for each cluster, we find hints that favor a picture in which massive clusters destroy UDGs in their centres.
