Optical Identifications of High-Redshift Galaxy Clusters from the Planck Sunyaev-Zeldovich Survey
Aghanim, N.; Bikmaev, I. F.; Khamitov, I. M. +8 more
We present the results of optical identifications and spectroscopic redshift measurements for galaxy clusters from the second Planck catalogue of Sunyaev-Zeldovich sources (PSZ2) located at high redshifts, z ≈ 0.7-0.9. We used the data of optical observations with the Russian-Turkish 1.5-mtelescope (RTT-150), the Sayan Observatory 1.6-m telescope,…
An extension of the Planck galaxy cluster catalogue
Burenin, R. A.
We present a catalogue of galaxy clusters detected in the Planck all-sky Compton parameter maps and identified using data from the WISE and SDSS surveys. The catalogue comprises about 3000 clusters in the SDSS fields. We expect the completeness of this catalogue to be high for clusters with masses larger than M 500 ≈ 3 × 1014…
Additional spectroscopic redshift measurements for galaxy clusters from the first Planck catalogue
Aghanim, N.; Melnikov, S. S.; Irtuganov, E. N. +10 more
We present the results of spectroscopic redshift measurements for the galaxy clusters from the first all-sky Planck catalogue that have been mostly identified based on the optical observations performed previously by our team (Planck Collaboration 2015a). Data on 13 galaxy clusters at redshifts from z ≈ 0.2 to z ≈ 0.8, including the improved ident…
Steep-spectrum sources of the RCR catalog in the millimeter and submillimeter ranges based on Planck data
Verkhodanov, O. V.; Majorova, E. K.; Zhelenkova, O. P. +2 more
We have investigated the regions of cosmic microwave background maps from the Planck experiment in the neighborhoods of radio sources from the RCR catalog. Based on the measurements of sources from the Planck catalog, we have constructed the calibration curves to determine the brightness of objects. For 34 steep-spectrum objects, for the first tim…
