摘要:

极红类星体,其热光度超过$10^{47}$ erg s $^{-1}$,是一个迷人的高红移群体,在本地宇宙中不存在。它们是超大质量黑洞以爱丁顿极限或以上的速率吸积的最佳候选者,并且它们与迄今为止已知的最快速和最强大的电离气体流出有关。它们也是大质量星系的宿主。在这里,我们提出了第一个积分场单位(IFU)的观测高红移类星体的近红外光谱仪(NIRSpec)上的詹姆斯韦伯太空望远镜(JWST),目标SDSSJ 165202.64 +172852.3,一个非常红的类星体在$z=2.94$。JWST观测揭示了扩展的电离气体-如[OIII] $λ$ 5007所追踪的-在类星体的宿主星系,其流出物和环星系介质中。复杂的形态学和运动学意味着类星体居住在一个非常密集的环境中,在10-15 kpc的投影距离内有几个相互作用的同伴星系。环境的高密度和伴随星系的大速度表明,这个系统可能代表了一个正在形成的星系团的核心。该系统是两个或多个暗物质晕合并的良好候选者,每个暗物质晕的质量为几个$10^{13}$ M $_\odot$,并可能追踪到$z\sim3$处的一个暗物质结。

英文摘要:

Extremely red quasars, with bolometric luminosities exceeding $10^{47}$ erg s$^{-1}$, are a fascinating high-redshift population that is absent in the local universe. They are the best candidates for supermassive black holes accreting at rates at or above the Eddington limit, and they are associated with the most rapid and powerful outflows of ionized gas known to date. They are also hosted by massive galaxies. Here we present the first integral field unit (IFU) observations of a high-redshift quasar obtained by the Near Infrared Spectrograph (NIRSpec) on board the James Webb Space Telescope (JWST), which targeted SDSSJ165202.64+172852.3, an extremely red quasar at $z=2.94$. JWST observations reveal extended ionized gas - as traced by [OIII]$λ$5007Å- in the host galaxy of the quasar, its outflow, and the circumgalactic medium. The complex morphology and kinematics imply that the quasar resides in a very dense environment with several interacting companion galaxies within projected distances of 10-15 kpc. The high density of the environment and the large velocities of the companion galaxies suggest that this system may represent the core of a forming cluster of galaxies. The system is a good candidate for a merger of two or more dark matter halos, each with a mass of a few $10^{13}$ M$_\odot$ and traces potentially one of the densest knots at $z\sim3$.
