论文摘要
这项工作介绍了宇宙星形峰值形成的结构形成的首次全面研究，超过$ 1.4 \ leq z \ leq 3.6 $在宇宙领域，包括那个时代最庞大的高红移星系proto群。我们将扩展的宇宙出生算法应用于Lagrangian初始宇宙时代的多跟踪和多 - 调查贝叶斯分析。结合五个不同的光谱红移监视（Zcosmos，Vuds，Mosdef，Zfire和FMOS-Cosmos）的数据，我们表明，如果可以通过适当的调查计算，则可以在附件的光学范围内进行适当的调查，并将不合格的估算方法置于非偏见的情况下，并且可以确定相应的无偏见的原始密度领域，并且可以将其进行不合格的旨在处理，并进行了精确的旨在处理，并且可以将其进行不合格的验证，并且可以通过不合格的方式进行验证，并且可以将其用于精确的计算。 （i）引力物质位移，（ii）特殊的速度和（iii）星系偏置。这些重建揭示了对宇宙领域中已知的原始群体的整体观点，以及宇宙网的生长向较低的红移。推断的遥远的暗物质密度场与其他探针（如层析成分的重建）同时探索气体和暗物质的相互作用，并且非常适合在即将进行的深度调查的情况下研究高红移的结构形成。
This work presents the first comprehensive study of structure formation at the peak epoch of cosmic star formation over $1.4\leq z \leq 3.6$ in the COSMOS field, including the most massive high redshift galaxy proto-clusters at that era. We apply the extended COSMIC BIRTH algorithm to account for a multi-tracer and multi-survey Bayesian analysis at Lagrangian initial cosmic times. Combining the data of five different spectroscopic redshift surveys (zCOSMOS-deep, VUDS, MOSDEF, ZFIRE, and FMOS-COSMOS), we show that the corresponding unbiased primordial density fields can be inferred, if a proper survey completeness computation from the parent photometric catalogs, and a precise treatment of the non-linear and non-local evolution on the light-cone is taken into account, including (i) gravitational matter displacements, (ii) peculiar velocities, and (iii) galaxy bias. The reconstructions reveal a holistic view on the known proto-clusters in the COSMOS field and the growth of the cosmic web towards lower redshifts. The inferred distant dark matter density fields concurrently with other probes like tomographic reconstructions of the intergalactic medium will explore the interplay of gas and dark matter and are ideally suited to study structure formation at high redshifts in the light of upcoming deep surveys.
