论文摘要
银河系的多波长研究对于了解它们的形成和进化很重要。仅在最近的过去,由于Atacama大(亚)毫米阵列(ALMA),我们能够研究高红移的星系的远红外(IR)特性。在本文中,我们总结了最新的研究及其对我们对高山调查早期星系进化的理解的意义,Alpine调查是一个大型ALMA的大型计划,可观察灰尘连续性和158UM C+在z = 4-6处正常星形星系的发射。与近红外波长在UV处的辅助数据相结合,ALPINE提供了当前最大的重新电源后星系中的多波伦长样本样本,并提出了我们对(i)C+发射人口统计学的理解; (ii)恒星形成和C+发射的关系; (iii)气体含量; (iv)流层间培养基的流出和富集; (v)Z> 4处星系中的运动学,磁盘的出现以及合并率。高山建立了下一代望远镜的基础,以实现更详细的测量,并将其本身作为重新电位后基线样本,从而允许在130亿年的宇宙时间内连续研究星系。
A multiwavelength study of galaxies is important to understand their formation and evolution. Only in the recent past, thanks to the Atacama Large (Sub) Millimeter Array (ALMA), were we able to study the far-infrared (IR) properties of galaxies at high redshifts. In this article, we summarize recent research highlights and their significance to our understanding of early galaxy evolution from the ALPINE survey, a large program with ALMA to observe the dust continuum and 158um C+ emission of normal star-forming galaxies at z = 4-6. Combined with ancillary data at UV through near-IR wavelengths, ALPINE provides the currently largest multiwavelength sample of post-reionization galaxies and has advanced our understanding of (i) the demographics of C+ emission; (ii) the relation of star formation and C+ emission; (iii) the gas content; (iv) outflows and enrichment of the intergalactic medium; and (v) the kinematics, emergence of disks, and merger rates in galaxies at z > 4. ALPINE builds the basis for more detailed measurements with the next generation of telescopes, and places itself as an important post-reionization baseline sample to allow a continuous study of galaxies over 13 billion years of cosmic time.
