Prospects for high-z cluster detections with Planck, based on a follow-up of 28 candidates using MegaCam@CFHT
R. F. J. van der Burg,H. Aussel,G. W. Pratt,M. Arnaud,J.-B. Melin,Nabila Aghanim,R. Barrena,Håkon Dahle,M. Douspis,A. Ferragamo,S. Fromenteau,R. Herbonnet,G. Hurier,E. Pointecouteau,Jose Alberto Rubino-Martin,Alina Streblyanska +15 more
TL;DR: In this article, the authors follow-up a sample of SZ sources from the Planck SZ catalogues from 2013 and 2015, and confirm that 16 of the candidates have likely optical counterparts to their SZ signals, 13 (6) of which have an estimated redshift z>0.7.

TL;DR: The Cluster HEritage project with XMM-Newton - Mass Assembly and Thermodynamics at the Endpoint of structure formation (CHEX-MATE) is a three mega-second multi-year Heritage Programme to obtain X-ray observations of a minimally-biased, signal-to-noise limited sample of 118 galaxy clusters detected by Planck through the Sunyaev-Zeldovich effect as mentioned in this paper.
Biases in galaxy cluster velocity dispersion and mass estimates in the small number of galaxies regime
A. Ferragamo,Jose Alberto Rubino-Martin,J. Betancort-Rijo,E. Munari,Barbara Sartoris,R. Barrena +5 more
TL;DR: In this article, a study of the statistical properties of three velocity dispersion and mass estimators, namely biweight, gapper and standard deviation, in the small number of galaxies regime is presented.

A. Paliwal,E. Artis,Weiguang Cui,M. De Petris,F.-X. Désert,A. Ferragamo,Giulia Gianfagna,Florian Kéruzoré,J. F. Macías-Pérez,F. Mayet,Miren Muñoz-Echeverría,L. Perotto,E. Rasia,Florian Ruppin,Gustavo Yepes +14 more
TL;DR: In this article, two samples of synthetic clusters of galaxies with properties close to the targets of the NIKA2 camera Sunyaev-Zeldovich (SZ) Large Program have been generated from The Three-Hundred-Projects Project simulations database.
Optical validation and characterization of Planck PSZ2 sources at the Canary Islands observatories. II. Second year of LP15 observations
A. Aguado-Barahona,R. Barrena,Alina Streblyanska,A. Ferragamo,Jose Alberto Rubino-Martin,D. Tramonte,H. Lietzen +6 more
TL;DR: In this article, the second and last year of observations of the optical follow-up program 128-MULTIPLE-16/15B (LP15 ) at Roque de los Muchachos Observatory (La Palma), which has been developed with the aim of validating all the unidentified PSZ2 sources in the northern sky, with declination above -15deg, and with no correspondence in the first Planck catalogue PSZ1, were presented.
