cds-question@unistra.frgalaxiesphotometryhst-photometryvisible-astronomyinfrared-astronomyredshiftedsurveysgravitational-lensingabsolute-magnitudegalaxy-clustersWe present constraints on the physical properties (including stellar mass, age, and star formation rate) of 207 6<=z<=8 galaxy candidates from the Reionization Lensing Cluster Survey (RELICS) and Spitzer-RELICS surveys. We measure photometry using T-PHOT and perform spectral energy distribution fitting using EAzY and BAGPIPES. Of the 207 candidates for which we could successfully measure (or place limits on) Spitzer fluxes, 23 were demoted to likely z<4. Among the high-z candidates, we find intrinsic stellar masses between 1x10^6^M_{sun}_ and 4x10^9^M_{sun}_, and rest-frame UV absolute magnitudes between -22.6 and -14.5mag. While our sample is mostly comprised of L_mUV_/L_mUV_^*^<1 galaxies, it extends to L_mUV_/L_mUV_^*^~2. Our sample spans ~4 orders of magnitude in stellar mass and star formation rates, and exhibits ages that range from maximally young to maximally old. We highlight 11 z>=6.5 galaxies with detections in Spitzer/IRAC imaging, several of which show evidence for some combination of evolved stellar populations, large contributions of nebular emission lines, and/or dust. Among these is PLCKG287+32-2013, one of the brightest z~7 candidates known (AB mag 24.9 at 1.6{mu}m) with a Spitzer 3.6{mu}m flux excess suggesting strong [OIII]+H-{beta} emission (~1000{AA} rest-frame equivalent width). We discuss the possible uses and limits of our sample and present a public catalog of Hubble + Spitzer photometry along with physical property estimates for all objects in the sample.2021ApJ...910..135Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/910/135CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/738/69 : SEDs of galaxies at 3.8<z<5 in GOODS (Shim+, 2011)J/ApJS/199/25 : CLASH sources for MACS1149.6+2223 (Postman+, 2012)J/ApJ/762/L30 : CLASH: MCS J0416.1-2403 strong lensing analysis (Zitrin+, 2013)J/A+A/568/L8 : VUDS extreme emission line 0.2<~z<~0.9 galaxies (Amorin+, 2014)J/ApJ/801/44 : HST lensing analysis of the CLASH sample (Zitrin+, 2015)J/A+A/590/A31 : ASTRODEEP Frontier Fields Catalogues (Merlin+, 2016)J/ApJ/839/L11 : HST strong lensing analysis of PLCKG287.0+32.9 (Zitrin+, 2017)J/ApJ/884/85 : RELICS: Reionization Lensing Cluster Survey (Coe+, 2019)J/A+A/643/A4 : ALPINE-ALMA [CII] survey.
