论文摘要

我们报告了一个活跃的银河核(AGN),其在剩余框架中具有极高的等效宽度(EW),EW(LYA+NV,REST)> 921 AA,在Hobby-Eby-eby-ebyly望远镜的暗能量实验(HETDEX)中,在Z〜2.24中是高EW EW AGN人群的代表性情况。连续水平是Hetdex频谱中的未检测,因此测得的EW是下限。在HETDEX(3500 AA -5500 AA)的波长覆盖范围内,在Lya+NV,CIV和中度发射线(〜4sigma)处使用明显的发射线(> 7sigma)检测到源。 R-BAND幅度为24.57,来自超弹药 - hetdex关节调查,检测极限为r = 25.12,在5sigma时。 LYA发射线横跨直径约为10 Arcsec(85 kpc)的明确解析区域。 LYA线的轮廓强烈峰值。频谱分解的蓝色气体和红色气体$α$发射的发射分离约1.2 Arcsec(10.1 kpc),视线速度偏移量为〜1100 km/s。该来源可能是一个有强大风的模糊的AGN。

We report an Active Galactic Nucleus (AGN) with extremely high equivalent width (EW), EW(LyA+NV,rest)>921 AA in the rest-frame, at z~2.24 in the Hobby-Eberly Telescope Dark Energy Experiment Survey (HETDEX) as a representative case of the high EW AGN population. The continuum level is a non-detection in the HETDEX spectrum, thus the measured EW is a lower limit. The source is detected with significant emission lines (>7sigma) at LyA+NV, CIV, and moderate emission line (~4sigma) at HeII within the wavelength coverage of HETDEX (3500 AA - 5500 AA). The r-band magnitude is 24.57 from the Hyper Suprime-Cam-HETDEX joint survey with a detection limit of r=25.12 at 5sigma. The LyA emission line spans a clearly resolved region of ~10 arcsec (85 kpc) in diameter. The LyA line profile is strongly double peaked. The spectral decomposed blue gas and red gas Ly$α$ emission are separated by ~1.2 arcsec (10.1 kpc) with a line-of-sight velocity offset of ~1100 km/s. This source is probably an obscured AGN with powerful winds.
