Title: | A Powerful Radio-loud Quasar at the End of Cosmic Reionization | Authors: | Bañados, Eduardo Carilli, Chris Walter, Fabian Momjian, Emmanuel DECARLI, ROBERTO Farina, Emanuele P. Mazzucchelli, Chiara Venemans, Bram P. |
Issue Date: | 2018 | Journal: | THE ASTROPHYSICAL JOURNAL LETTERS | Number: | 861 | Issue: | 2 | First Page: | L14 | Abstract: | We present the discovery of the radio-loud quasar PSO J352.4034-15.3373 at z = 5.84 ± 0.02. This quasar is the radio brightest source known, by an order of magnitude, at z ∼ 6 with a flux density in the range of 8-100 mJy from 3 GHz to 230 MHz and a radio loudness parameter R={f}<SUB>ν ,5{GHz</SUB>}/{f}<SUB>ν ,4400\mathringA </SUB>≳ 1000. This source provides an unprecedented opportunity to study powerful jets and radio-mode feedback at the highest redshifts, and presents the first real chance to probe deep into the neutral intergalactic medium by detecting 21 cm absorption at the end of cosmic reionization. | URI: | http://hdl.handle.net/20.500.12386/27480 | URL: | https://iopscience.iop.org/article/10.3847/2041-8213/aac511 | ISSN: | 2041-8205 | DOI: | 10.3847/2041-8213/aac511 | Bibcode ADS: | 2018ApJ...861L..14B | Fulltext: | open |
