论文摘要
线强度映射（LIM）是测量星系演化和宇宙大规模结构的新兴技术。 LIM调查测量所有在特定红移处发射给定线的星系的累积发射，该线路在整个宇宙中追踪了暗物质的分布。在此程序中，我们为LIM建模提供了介绍，重点是功率谱计算。除了这些计算之外，我们还描述了如何使用这些功率谱来限制星系进化和大规模结构宇宙学的性质。在整个过程中，我们以红移$ z = 3 $的电离碳（[CII]）的预期惊动信号作为案例研究。我们的目标是为非专家提供一个起点，例如熟悉宇宙学基础知识的高级本科生和研究生，具有了解文献并创造Lim Power Spectrum模型的必要工具，同时还描述了许多文献进行持续研究。
Line intensity mapping (LIM) is an emerging technique in measuring galaxy evolution and the large-scale structure of the universe. LIM surveys measure the cumulative emission from all galaxies emitting a given line at a particular redshift, which trace the distribution of dark matter throughout the universe. In this proceeding, we provide an introduction to LIM modeling, focusing on power spectrum calculation. Beyond these calculations, we describe how these power spectra may be used to constrain properties of galaxy evolution and large-scale structure cosmology. Throughout, we use the anticipated EXCLAIM signal of ionized carbon ([CII]) at redshift $z=3$ as a case study. Our goal is to provide a starting point to non-experts, e.g. upper-level undergraduate and graduate students familiar with the basics of cosmology, with the tools necessary to understand the literature and generate LIM power spectrum models themselves, while also describing a wide array of literature for continued studies.
