Three-dimensional dust mapping of the Milky Way using Gaia (B09)

星际尘埃在恒星的生命周期中起着至关重要的作用，也在吸收我们从天文光源接收到的光方面起着重要作用。推断这些尘埃在银河系中的三维分布对于研究这两个方面都很重要。在SFB前两个阶段完成和发表的工作的基础上，我们将扩展我们的非参数贝叶斯方法来绘制尘埃。此外，通过光学和红外测光，SDSS-V光谱，以及数百万颗恒星的Gaia-DR2/DR3 par-allax，我们将绘制出几kpc的尘埃图。我们的方法产生了一个合理的，连续的分布，甚至在未观察到的视线，在许多应用中很有用。

Interstellar dust plays an essential role in the life cycle of stars, as well as in absorbing the light we receive from astronomical sources. Inferring the 3-D distribution of this dust in our Galaxy is important for studying both these aspects. Building on work done and published in the first two phases of the SFB, we will extend our non-parametric Bayesian method of mapping dust. More-over, by using optical and infrared photometry, SDSS-V spectroscopy, and Gaia-DR2/DR3 par-allaxes of millions of stars, we will map dust out to several kpc. Our method produces a plausi-ble, continuous distribution even across unobserved lines of sight, useful in many applications.
