abstract

  • Abstract We searched for z gsim 7 Lyman-break galaxies in the optical-to-mid-infrared Hubble Frontier Field and associated parallel field observations of the strong-lensing cluster MACS J0416− 2403. We discovered 22 candidates, of which 6 lie at z gsim 9 and 1 lies at z gsim 10. Based on the Hubble and Spitzer photometry, all have secure photometric redshifts and a negligible probability of being at lower redshifts according to their peak-probability ratios, ${\mathcal {R}} $. This substantial increase in the number of known high-redshift …
