论文摘要
我们使用Atacama大毫米/亚毫米阵列(ALMA)的最新结果,以定位电离碳[CII] 158 $μ$ m和氧气[OIII] 88 $μ$ m线条,并结合数据驱动的预测中性氢(HI)的进化(HI),以示出21 c c c c c c c c c c c c c c c c c c c c cosm in forts corm insperts的进化(hi),以使其与数据驱动的预测相结合,以实现量度的进化,以实现量度的进化,并超过$ z \ sim 5-7 $的调查。我们与一个数据集合作,包括$ z \ sim 4.5-7 $的高山和叛军调查,以及$ z \ sim 6-9 $的Alma [OIII]检测。 [CII]发光度 - 光晕质量关系的结果演变在高红移处得到很好的描述,最合适的参数与模拟的结果非常吻合。该数据有利于[CII]的自动功率频谱的安全检测,并具有增强的Fred Young Imbillimetre望远镜(FYST)类似配置。这样的实验,以及默奇森广场阵列(MWA)将能够测量21 cm - [CII]互相关功率,其信噪比为几十至几百。我们发现,对低温大量强度映射的实验改进的气球传播实验应能够检测21 cm - [OIII]与MWA和平方英里阵列(SKA)(SKA)的互相关,以下是$ z \ sim \ sim 7 $。我们的结果对限制在电离的中端到端阶段限制发光源的演变具有影响。
We use the latest results from Atacama Large Millimetre/submillimetre Array (ALMA) surveys targeting the ionized carbon [CII] 158 $μ$m and oxygen [OIII] 88 $μ$m lines, in combination with data-driven predictions for the evolution of neutral hydrogen (HI), to illustrate the prospects for intensity mapping cross-correlations between 21 cm and submillimetre surveys over $z \sim 5-7$. We work with a dataset including the ALPINE and REBELS surveys for [CII] over $z \sim 4.5-7$, and ALMA [OIII] detections over $z \sim 6-9$. The resultant evolution of the [CII] luminosity - halo mass relation is well described by a double power law at high redshifts, with the best-fitting parameters in good agreement with the results of simulations. The data favour secure detections of the auto-power spectrum of [CII] at all redshifts with an enhanced Fred Young Submillimetre Telescope (FYST)-like configuration. Such an experiment, along with the Murchinson Widefield Array (MWA) will be able to measure the 21 cm - [CII] cross-correlation power with a signal-to-noise ratio of a few tens to a few hundreds. We find that a balloon-borne experiment improving upon the Experiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM) should be able to detect the 21 cm - [OIII] cross-correlation with the MWA and the Square Kilometre Array (SKA)-LOW out to $z \sim 7$. Our results have implications for constraining the evolution of luminous sources during the mid-to-end stages of reionization.
