Galaxy clusters are ideal witnesses of the cosmic large-scale evolution, and excellent laboratories to study the physics of the hot plasma that contains the bulk of the baryonic matter in the universe. Our APEX-SZ survey project presented the first published scientific results from observations with a large array of multiplexed, superconducting, transition edge sensors, and continues to produce unprecedented scientific data. In three observing runs since its commissioning in Spring 2007, we have mapped more than ten galaxy clusters, encompassing a wide range in mass and redshift, and obtained deep imaging data on selected “blank” fields. We have been focusing on a combined SZE-X-ray analysis to model the intra-cluster gas physics, and we have been pursuing multi-frequency imaging observations to study structure and to investigate SZE contaminants such as starburst and radio galaxies. We request continued funding for the three central German members of our international collaboration, in order to strongly pursue our research on the properties and evolution of galaxy clusters, on the physics of the hot intra-cluster gas, and on the cluster mass scaling relations, which are the crucial basis for cluster cosmology surveys.

星系簇是宇宙大规模进化的理想见证人，也是研究热等离子体物理学的出色实验室，其中包含宇宙中大部分重重的重量。我们的APEX-SZ调查项目通过观察结果提出了首次发表的科学结果，这些观察结果有一系列多路复用，超导，过渡边缘传感器，并继续产生前所未有的科学数据。自2007年春季委托以来，我们已经绘制了十个以上的星系簇，涵盖了质量和红移的范围，并在选定的“空白”字段中获得了深层成像数据。我们一直专注于组合的SZE-X射线分析，以模拟群内气体物理学，并且我们一直在追求多频成像观察，以研究结构并研究SZE污染物，例如Starburst和Radio Galaxies。我们要求继续为国际合作的三个中央德国中央成员提供资金，以便强烈追求有关星系簇的属性和进化，热热内气体的物理和集群质量扩展关系的研究，这是集群宇宙学调查的关键基础。
