“…The joint masses assuming these redshifts are M 500 = (5.9 ± 1.1) · 10 14 M and M 500 = (7.0 ± 1.3) · 10 14 M , respectively. The masses reported by Wen & Han (2018), M 500 = 7.37 · 10 14 M and M 500 = 3.05 · 10 14 M , respectively, do not have an associated error, but taking into account the possible uncertainties in the mass estimation at those high redshifts, they are compatible. By visually inspecting available ancillary images from WISE, PanSTARRS, SDSS, and Swift, both appear to be good associations, so we have classified these two candidates as confirmed (class 1).…”

“…First, we considered the sample of 1959 massive clusters of galaxies in the redshift range of 0.7 < z < 1.0 presented in Wen & Han (2018), which were found by searching around spectroscopically confirmed z > 0.7 LRGs in SDSS. We found two matches within a 5 arcmin radius with ComPRASS candidates that were not confirmed in the previous external validation: PSZRX G180.69+46.41 corresponds to Wen's J092829.4+410715 at z=0.8194 and had not been identified before; and PSZRX G271.62+61.69 corresponds to J115417.3+022124 at z=0.7118, and had been identified (but not confirmed) with one of the clusters of Burenin (2017).…”

We present the first all-sky catalogue of galaxy clusters and cluster candidates obtained from joint X-ray-SZ detections using observations from the Planck satellite and the ROSAT all-sky survey (RASS). The catalogue contains 2323 objects and has been validated by careful cross-identification with previously known clusters. This validation shows that 1597 candidates correspond to already known clusters, 212 coincide with other cluster candidates still to be confirmed, and the remaining 514 are completely new detections. With respect to Planck catalogues, the ComPRASS catalogue is simultaneously more pure and more complete. Based on the validation results in the SPT and SDSS footprints, the expected purity of the catalogue is at least 84.5%, meaning that more than 365 clusters are expected to be found among the new or still to be confirmed candidates with future validation efforts or specific follow-ups.

“…Classical systematic cluster searches were carried out via X-ray [e.g., refs. 77, 78], Sunyaev-Zeldovich [SZ; 79,80,81,82] and optical/near-infrared [83,84,85,86] surveys. These surveys, however, have yielded only a handful of confirmed proto-cluster detections at z ∼ > 1.5 [76].…”

Planck, SPT and ACT surveys have clearly demonstrated that Cosmic Microwave Background (CMB) experiments, while optimised for cosmological measurements, have made important contributions to the field of extragalactic astrophysics in the last decade. Future CMB experiments have the potential to make even greater contributions. One example is the detection of highz galaxies with extreme gravitational amplifications. The combination of flux boosting and of stretching of the images has allowed the investigation of the structure of galaxies at z 3 with the astounding spatial resolution of about 60 pc. Another example is the detection of proto-clusters of dusty galaxies at high z when they may not yet possess the hot intergalactic medium allowing their detection in X-rays or via the Sunyaev-Zeldovich effect. Next generation CMB experiments, like PICO, CORE, CMB-Bharat from space and Simons Observatory and CMB-S4 from the ground, will discover several thousands of strongly lensed galaxies out to z ∼ 6 or more and of 1 arXiv:1907.05323v1 [astro-ph.GA] 11 Jul 2019 De Zotti et al.

Moreover they will measure the polarized emission of thousands of radio sources and of dusty galaxies at mm/sub-mm wavelengths.

Observational systematics complicate comparisons with theoretical models limiting understanding of galaxy evolution. In particular, different empirical determinations of the stellar mass function imply distinct mappings between the galaxy and halo masses, leading to diverse galaxy evolutionary tracks. Using our state-of-the-art STatistical sEmi-Empirical modeL, steel, we show fully self-consistent models capable of generating galaxy growth histories that simultaneously and closely agree with the latest data on satellite richness and star-formation rates at multiple redshifts and environments. Central galaxy histories are generated using the central halo mass tracks from state-of-the-art statistical dark matter accretion histories coupled to abundance matching routines. We show that too flat high-mass slopes in the input stellar-masshalo-mass relations as predicted by previous works, imply non-physical stellar mass growth histories weaker than those implied by satellite accretion alone. Our best-fit models reproduce the satellite distributions at the largest masses and highest redshifts probed, the latest data on star formation rates and its bi-modality in the local Universe, and the correct fraction of ellipticals. Our results are important to predict robust and self-consistent stellar-mass-halo-mass relations and to generate reliable galaxy mock catalogues for the next generations of extra-galactic surveys such as Euclid and LSST.
