论文摘要
许多星系显示清晰的凸起和圆盘,并了解这些组件形式如何是了解银河系如何发展为我们今天所看到的至关重要的一步。 Buddi-Manga项目旨在通过凸起和圆盘的星形成历史来研究星系进化和形态转化。我们已将Buddi软件应用于SDSS DR15的漫画调查的星系,以隔离它们的凸起和碟片谱,从中我们得出了其出色的种群。迄今为止,这项工作提供了使用Galaxies光谱信息从IFU数据存储中提取的最大的清洁凸起和光盘谱,并将为一系列论文构成旨在回答有关星系如何形成和进化的开放问题的基础,以及其各个结构的作用。本文介绍了该项目的介绍,包括对这些拟合的概述,样本的特征以及对拟合的一系列测试,以确保可靠性。
Many galaxies display clear bulges and discs, and understanding how these components form is a vital step towards understanding how the galaxy has evolved into what we see today. The BUDDI-MaNGA project aims to study galaxy evolution and morphological transformations through the star-formation histories of the bulges and discs. We have applied our BUDDI software to galaxies from the MaNGA Survey in the SDSS DR15 in order to isolate their bulge and disc spectra, from which we derived their stellar populations. To date, this work provides the largest sample of clean bulge and disc spectra extracted from IFU datacubes using the galaxies light profile information, and will form the basis for a series of papers aiming to answer open questions on how galaxies have formed and evolved, and the role of their individual structures. This paper presents an introduction to the project, including an overview of these fits, a characterisation of the sample, and a series of tests on the fits to ensure reliability.
