通过对背景类恒星天体-光谱的吸收，成功地研究了atz < 6的环星系介质的物理化学性质。最关键的问题之一是调查产生这些早期金属吸收体-的源星系的性质和位置。理论模型表明，典型的恒星形成星系的动量驱动流出物可以将金属喷射到星系周围介质和星系间介质atz= 5-6。, -)。深入的、专门的调查已经寻找了与强Civabsorbers atz≈6相关的Lyα发射，但只检测到少数Lyα-发射候选体。此外，对这些探测结果的解释也很模糊，因为Lyα是一条共振线，-，这就需要补充技术来探测吸收器的宿主星系。本文报道了使用阿塔卡马大型毫米波阵列检测到的一个[Cii] 158 μm发射器，该发射器与强低电离吸收剂Oi相关，atz= 5.978。预估的oland和[Cii]发射器之间的冲击参数为20.0 kpc。测量的[Cii]光度为7.0 × 107太阳光度。进一步的分析表明，强吸油器可能存在于比预期质量大一到两个数量级的大质量晕的环星系介质中。
The physical and chemical properties of the circumgalactic medium atz≳ 6 have been studied successfully through the absorption in the spectra of background quasi-stellar objects, –. One of the most crucial questions is to investigate the nature and location of the source galaxies that give rise to these early metal absorbers, –. Theoretical models suggest that momentum-driven outflows from typical star-forming galaxies can eject metals into the circumgalactic medium and the intergalactic medium atz= 5–6 (refs., –). Deep, dedicated surveys have searched for Lyα emission associated with strong Civabsorbers atz≈ 6, but only a few Lyα-emitter candidates have been detected. Interpreting these detections is moreover ambiguous because Lyα is a resonant line, –, raising the need for complementary techniques for detecting absorbers’ host galaxies. Here we report a [Cii] 158 μm emitter detected using the Atacama Large Millimeter Array that is associated with a strong low-ionization absorber, Oi, atz= 5.978. The projected impact parameter between Oiand [Cii] emitter is 20.0 kpc. The measured [Cii] luminosity is 7.0 × 107solar luminosities. Further analysis indicates that strong Oiabsorbers may reside in the circumgalactic medium of massive halos one to two orders of magnitude more massive than expected values,.
