ComPRASS：一个X射线-SZ团簇的Planck-RASS组合星表
ComPRASS: a Combined Planck-RASS catalogue of X-ray-SZ clusters
摘要：
我们提出了第一个全天空的星系团和集群候选人从联合X射线-SZ探测使用观测普朗克卫星和ROSAT全天空巡天（RASS）。该目录包含2323个对象，并已通过仔细的交叉识别与以前已知的集群进行验证。该验证表明，1597个候选对应于已知的聚类，212个与仍待确认的其他聚类候选一致，其余514个是全新的检测。与普朗克星表相比，CompRASS星表更纯粹，也更完整。根据SPT和SDSS足迹的验证结果，目录的预期纯度至少为84.5%，这意味着在未来的验证工作或具体的后续工作中，预计将在新的或仍待确认的候选物中发现超过365个簇。
英文摘要：
We present the first all-sky catalogue of galaxy clusters and cluster candidates obtained from joint X-ray-SZ detections using observations from the Planck satellite and the ROSAT all-sky survey (RASS). The catalogue contains 2323 objects and has been validated by careful cross-identification with previously known clusters. This validation shows that 1597 candidates correspond to already known clusters, 212 coincide with other cluster candidates still to be confirmed, and the remaining 514 are completely new detections. With respect to Planck catalogues, the ComPRASS catalogue is simultaneously more pure and more complete. Based on the validation results in the SPT and SDSS footprints, the expected purity of the catalogue is at least 84.5%, meaning that more than 365 clusters are expected to be found among the new or still to be confirmed candidates with future validation efforts or specific follow-ups.
