Abstract

We present the results of spectroscopic redshift measurements for galaxy clusters from the catalogue compiled previously from Planck all-sky survey data in combination with Sloan Digital Sky Survey (SDSS) and WISE data in the optical and infrared ranges. Most of these clusters are massive objects that will also be detected in future all-sky surveys, such as the eROSITA all-sky X-ray survey onboard the Spectrum–Roentgen–Gamma (SRG) space observatory. The spectroscopic observations of these galaxy clusters have been carried out with the 1.5-m Russian–Turkish telescope (RTT150), the 1.6-m Sayan Observatory AZT-33IK telescope, and the 6-m SAO RAS telescope (Bolshoi Teleskop Azimutalnyi, BTA). The spectroscopic redshift measurements have been obtained for 67 galaxy clusters, including 12 galaxy clusters from the second Planck catalogue of Sunyaev–Zeldovich sources.

在普朗克全天候测量中检测到的银河星团的光谱红移测量

摘要

我们从普朗克全天候测量数据与斯隆数字天空测量（SDSS）以及WISE数据在光学和红外范围的组合中，从先前编制的目录中提供了星系团的光谱红移测量结果。这些星团中的大多数都是巨大的物体，将来也将在全天候勘测中检测到，例如，光谱-伦琴-伽玛（SRG）天文台上的eROSITA全天巡视X射线勘测。这些星系团的光谱观测是使用1.5米的俄罗斯-土耳其望远镜（RTT150），1.6米的萨彦天文台AZT-33IK望远镜和6米的SAO RAS望远镜（Bolshoi Teleskop Azimutalnyi，BTA）进行的。已经获得了67个星系团的光谱红移测量值，
