论文摘要
高红移和大型结构的联合分析为未开发的早期结构形成时代提供了新的独特窗口。在这里，我们证明了如何使用动力锥圆锥体使用动力锥圆锥体探测宇宙红外背景和高红移星系，以探测氦气回去时期（$ 2 <z <4 $）。表征这个时期具有理解星体形成的天体物理学，类星体活性和超质量黑洞的形成具有巨大的潜在意义。我们发现，从即将到来的几年中，CCAT-Prime，Vera Rubin天文台和CMB-S4的数据的组合可以预期以$8-10σ$的价格进行检测。
Joint analysis of CMB and large-scale structure at high redshifts provide new and unique windows into unexplored epochs of early structure formation. Here, we demonstrate how cosmic infrared background and high-redshift galaxies can be jointly analysed with CMB to probe the epoch of helium reionization ($2<z<4$) on the light cone using kinetic Sunyaev Zel'dovich tomography. Characterising this epoch has great potential significance for understanding astrophysics of galaxy formation, quasar activity and formation of the super-massive black holes. We find a detection at $8-10σ$ can be expected from combinations of data from CCAT-prime, Vera Rubin Observatory and CMB-S4 in the upcoming years.
