Additional spectroscopic redshift measurements for galaxy clusters from the First Planck Catalogue
We present the results of spectroscopic redshift measurements for the galaxy
clusters from the first all-sky Planck catalogue of the Sunyaev-Zeldovich
sources, that have been mostly identified by means of the optical observations
performed previously by our team (Planck Collaboration, 2015a). The data on 13
galaxy clusters at redshifts from z=~0.2 to z=~0.8, including the improved
identification and redshift measurement for the cluster PSZ1 G141.73+14.22 at
z=0.828, are provided. The measurements were done using the data from
Russian-Turkish 1.5-m telescope (RTT-150), 2.2-m Calar Alto Observatory
telescope, and 6-m SAO RAS telescope (Bolshoy Teleskop Azimutalnyi, BTA).Comment: published in Astronomy Letter
