MACS J1149.5+2223 | Autor: | Zheng, Wei; Zitrin, Adi; Infante, Leopoldo; Laporte, Nicolas; Huang, Xingxing; Moustakas, John; Ford, Holland C.; Shu, Xinwen; Wang, J.; Diego, José María CSIC ORCID ; Bauer, F.E.; Troncoso Iribarren, P.; Broadhurst, Tom; Molino, Alberto CSIC ORCID | Fecha de publicación: | 2017 | Editor: | Institute of Physics Publishing | Citación: | Astrophysical Journal 836(2): 210 (2017) | Resumen: | We search for high-redshift dropout galaxies behind the Hubble Frontier Fields (HFF) galaxy cluster MACS J1149.5+2223, a powerful cosmic lens that has revealed a number of unique objects in its field. Using the deep images from the Hubble and Spitzer space telescopes, we find 11 galaxies at z > 7 in the MACS J1149.5+2223 cluster field, and 11 in its parallel field. The high-redshift nature of the bright z ≃ 9.6 galaxy MACS1149-JD, previously reported by Zheng et al., is further supported by non-detection in the extremely deep optical images from the HFF campaign. With the new photometry, the best photometric redshift solution for MACS1149-JD reduces slightly to z = 9.44 ± 0.12. The young galaxy has an estimated stellar mass of , and was formed at when the universe was ≈300 Myr old. Data available for the first four HFF clusters have already enabled us to find faint galaxies to an intrinsic magnitude of , approximately a factor of 10 deeper than the parallel fields. | Descripción: | arXiv:1701.08484v2 | Versión del editor: | https://doi.org/10.3847/1538-4357/aa5d55 | URI: | http://hdl.handle.net/10261/170673 | DOI: | 10.3847/1538-4357/aa5d55 | Identificadores: | doi: 10.3847/1538-4357/aa5d55 e-issn: 1538-4357 issn: 0004-637X |
