摘要

在这篇综述中，我们展示了如何将动力学和恒星人口模型与附近星系的积分场光谱数据相结合，从而揭示它们的组装历史。▪我们讨论了各种动力学建模方法的优点和局限性，重点是测量附近星系的质量分布，包括中心黑洞和暗物质晕。▪我们强调使用史瓦西轨道叠加法稳健地将星系分解为动态不同的组成部分，并推导出它们的内在性质。▪我们涵盖了应用单恒星人口模型来解释附近星系中未解析恒星的观测结果。▪我们概述了如何结合动力学和恒星人口模型来揭示星系组合的化石记录，从内部星系结构的起源，到磁盘的形成，再到过去星系合并的恢复。最后，我们展示了这些邻近星系的模型如何在局部宇宙中分辨恒星的研究和高红移星系的观测之间提供了一座桥梁。再加上直接耦合到最先进的宇宙学模拟，银河系外考古学承诺了对星系形成和演化的关键见解。

Extragalactic Archaeology: The Assembly History of Galaxies from Dynamical and Stellar Population Models

In this review, we show how combining dynamical and stellar population models with integral field spectroscopic data of nearby galaxies enable uncovering their assembly history.

▪ We discuss the advantages and limitations of various dynamical modelling approaches, focusing on measuring the mass distributions of nearby galaxies, including central black holes and dark matter halos.

▪ We highlight the use of Schwarzschild's orbit-superposition method to robustly decompose galaxies into dynamically distinct components and derive their intrinsic properties.

▪ We cover the application of single stellar population models to interpret observations of unresolved stars in nearby galaxies.

▪ We outline how combining dynamical and stellar population models can reveal the fossil records of galaxy assembly, from the origin of inner galaxy structures, to the buildup of disks, to the recovery of past galaxy mergers.

We close by demonstrating how these models of nearby galaxies provide a bridge between studies of resolved stars in the local Universe and high-redshift galaxy observations. Together with direct coupling to state-of-the-art cosmological simulations, extragalactic archaeology promises key insights into galaxy formation and evolution.
