标题： GECKOS: Turning galaxy evolution on its side with deep observations of edge-on galaxies

摘要： 我们介绍了GECKOS（Generalising Edge-on galaxies and their Chemical bimodalities, Kinematics, and Outflows out to Solar environments），这是一个新的ESO VLT/MUSE大型项目。 GECKOS的主要目标是通过将银河考古学与附近星系的积分场光谱观测相结合，揭示盘状星系形成的关键物理过程的变化。 边缘星系非常适合这项任务：它们允许我们解开厚盘中留下的组装历史，并提供对外流的最大洞察力。 由35个附近的边缘盘状星系组成的GECKOS样本旨在追踪跨越大量恒星形成率、核球与总质量比以及有盒状和无盒状核球的星系的组装历史和属性。 GECKOS将提供空间分辨的恒星丰度、年龄和动力学测量，以及电离气体金属丰度、电离参数、压力及流入流出动力学；所有这些关键参数对于构建完整的盘状星系化学动力学图景至关重要。 利用这些数据，我们旨在将银河分析方法扩展到更广泛的星系群体，收获详细研究银河系的好处，同时探测星系演化的多样化机制。 显示英文摘要

摘要： We present GECKOS (Generalising Edge-on galaxies and their Chemical bimodalities, Kinematics, and Outflows out to Solar environments), a new ESO VLT/MUSE large program. The main aim of GECKOS is to reveal the variation in key physical processes of disk formation by connecting Galactic Archaeology with integral field spectroscopic observations of nearby galaxies. Edge-on galaxies are ideal for this task: they allow us to disentangle the assembly history imprinted in thick disks and provide the greatest insights into outflows. The GECKOS sample of 35 nearby edge-on disk galaxies is designed to trace the assembly histories and properties of galaxies across a large range of star formation rates, bulge-to-total ratios, and boxy and non-boxy bulges. GECKOS will deliver spatially resolved measurements of stellar abundances, ages, and kinematics, as well as ionised gas metallicities, ionisation parameters, pressure, and inflow and outflow kinematics; all key parameters for building a complete chemodynamical picture of disk galaxies. With these data, we aim to extend Galactic analysis methods to the wider galaxy population, reaping the benefits of detailed Milky Way studies, while probing the diverse mechanisms of galaxy evolution.
