cds-question@unistra.frgalaxy-clustersgalaxiesinfrared-sourceshst-photometryredshiftedsurveysvisible-astronomyMassive foreground galaxy clusters magnify and distort the light of objects behind them, permitting a view into both the extremely distant and intrinsically faint galaxy populations. We present here the z~6-8 candidate high-redshift galaxies from the Reionization Lensing Cluster Survey (RELICS), a Hubble and Spitzer Space Telescope survey of 41 massive galaxy clusters spanning an area of ~200arcmin^2^. These clusters were selected to be excellent lenses, and we find similar high-redshift sample sizes and magnitude distributions as the Cluster Lensing And Supernova survey with Hubble (CLASH). We discover 257, 57, and eight candidate galaxies at z~6, 7, and 8 respectively, (322 in total). The observed (lensed) magnitudes of the z~6 candidates are as bright as AB mag ~23, making them among the brightest known at these redshifts, comparable with discoveries from much wider, blank-field surveys. RELICS demonstrates the efficiency of using strong gravitational lenses to produce high-redshift samples in the epoch of reionization. These brightly observed galaxies are excellent targets for follow-up study with current and future observatories, including the James Webb Space Telescope.2020ApJ...889..189Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/889/189CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/150/1 : VV29 and NGC 4676 HST photometry (Benitez+, 2004)J/AJ/132/1729 : HUDF BVI-dropout sources (Beckwith+, 2006)J/AJ/132/926 : Galaxies in the Hubble Ultra Deep Field (Coe+, 2006)J/A+A/534/A109 : MCXC Meta-Catalog X-ray galaxy Clusters (Piffaretti+, 2011)J/A+A/544/A156 : UltraVISTA Catalog Release DR1 (McCracken+, 2012)J/ApJS/199/25 : CLASH sources for MACS1149.6+2223 (Postman+, 2012)J/ApJS/199/34 : Clusters of galaxies in SDSS-III (Wen+, 2012)J/MNRAS/432/2696 : Galaxy luminosity function at z = 7-9 (McLure+, 2013)J/ApJ/769/52 : SDSS luminous red galaxies concentrations (Wong+, 2013)J/MNRAS/440/2810 : Galaxy luminosity function at z =~ 7 (Bowler+, 2014)J/ApJ/792/76 : Lensed z~6-8 galaxies behind CLASH clusters (Bradley+, 2014)J/ApJ/800/18 : HST/WFC3 obs. of z~7-8 galaxies in A2744 (Atek+, 2015)J/ApJS/216/27 : Gal. clusters discovered in the SPT-SZ survey (Bleem+, 2015)J/ApJ/803/34 : z~4-10 galaxies from HST legacy fields (Bouwens+, 2015)J/ApJ/810/71 : UV mag of cand. galaxies at 3~<z~<8.5 (Finkelstein+, 2015)J/ApJ/814/L6 : CIII] emission in star-forming galaxies (Rigby+, 2015)J/MNRAS/450/3665 : CoMaLit.
