Planck 2013结果XXIX。Sunyaev-Zeldovich源的普朗克星表:补遗
Planck 2013 results. XXIX. The Planck catalogue of Sunyaev-Zeldovich sources: Addendum
摘要:
我们更新了2013年3月发布的1227个星团和候选星团的全天普朗克星表(PSZ 1),这些星团和候选星团是使用普朗克卫星观测的前15.5个月的Sunyaev-Zeldovich(SZ)效应探测得出的。增编我们提供了PSZ 1目录的更新版本,报告了对86个普朗克发现的星团的进一步确认。PSZ 1现在总共包含947个已确认的星团,其中214个是通过普朗克合作组织进行的后续观测确认为新发现的星团。更新后的PSZ 1包含了913个系统的红移,其中736个(约80.6%)是光谱系统,以及由Y_z质量代理得到的相关质量估计。我们还提供了一个新的SZ质量标志,来自一个新的人工神经网络分类的SZ信号,其余的280名候选人。根据这一评估,更新后的PSZ 1目录的纯度估计为94%。在本新闻稿中,我们提供了完整的更新目录和一个附加的自述文件,其中包含有关普朗克SZ探测的进一步信息。
英文摘要:
We update the all-sky Planck catalogue of 1227 clusters and cluster candidates (PSZ1) published in March 2013, derived from Sunyaev-Zeldovich (SZ) effect detections using the first 15.5 months of Planck satellite observations. Addendum. We deliver an updated version of the PSZ1 catalogue, reporting the further confirmation of 86 Planck-discovered clusters. In total, the PSZ1 now contains 947 confirmed clusters, of which 214 were confirmed as newly discovered clusters through follow-up observations undertaken by the Planck Collaboration. The updated PSZ1 contains redshifts for 913 systems, of which 736 (~80.6%) are spectroscopic, and associated mass estimates derived from the Y_z mass proxy. We also provide a new SZ quality flag, derived from a novel artificial neural network classification of the SZ signal, for the remaining 280 candidates. Based on this assessment, the purity of the updated PSZ1 catalogue is estimated to be 94%. In this release, we provide the full updated catalogue and an additional readme file with further information on the Planck SZ detections.
