We analyzed the HFF to measure the volume density of Lyman-break galaxies at z>4.75 by identifying a complete and reliable sample up to z~10. A marked deficit of such galaxies was uncovered in the highly magnified regions of the clusters relative to their outskirts, implying that the magnification of the sky area dominates over additional faint galaxies magnified above the flux limit. This negative magnification bias is consistent with a slow rollover at the faint end of the UV luminosity function and it indicates a preference for Bose-Einstein condensate dark matter with a light boson mass of m_B_~10^-22^eV over standard cold dark matter. We emphasize that measuring the magnification bias requires no correction for multiply-lensed images (with typically three or more images per source), whereas directly reconstructing the luminosity function will lead to an overestimate unless such images can be exhaustively matched up, especially at the faint end that is only accessible in the strongly lensed regions. In addition, we detected a distinctive downward transition in galaxy number density at z>~8, which may be linked to the relatively late reionization reported by Planck. Our results suggests that JWST will likely peer into an "abyss" with essentially no galaxies detected in deep NIR imaging at z>10.2018ApJ...862..156Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/862/156CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/4 : Abell and Zwicky Clusters of Galaxies (Abell+ 1974)VII/110 : Rich Clusters of Galaxies (Abell+ 1989)J/ApJS/150/1 : VV29 and NGC 4676 HST photometry (Benitez+, 2004)J/AJ/132/926 : Galaxies in the Hubble Ultra Deep Field (Coe+, 2006)J/ApJS/199/25 : CLASH sources for MACS1149.6+2223 (Postman+, 2012)J/MNRAS/432/2696 : Galaxy luminosity function at z = 7-9 (McLure+, 2013)J/ApJ/793/115 : UV-continuum slopes beta for z~4-8 galaxies (Bouwens+, 2014)J/MNRAS/444/268 : HST Frontier Fields clusters (Richard+, 2014)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/MNRAS/452/1437 : Abell 2744 strong-lensing analysis (Jauzac+, 2015)J/ApJ/819/114 : Strong lensing mass modeling of 4 HFF cl.
