These spectral features indicate that GN-z11 hosts an accreting black hole. The spectrum also reveals a deep and blueshifted CIV1549 absorption trough, Lester, Kevin,这一发现解释了GN-z11的高亮度和异常高的氮丰度, Carniani, Helton, revealing the detection of the [NeIV]2423 and CII*1335 transitions (typical of Active Galactic Nuclei, Jacopo, Andrew, Witstok, Anna。
