利用公民科学方法,通过DESI遗产调查数据释放10中的图像,扩展重叠星系对目录,以提高尘埃消光研究的精度和自动化识别能力。

摘要:

重叠星系,即前景星系部分重叠背景星系,提供了一个独特的机会,通过建模前景和背景星系的光,并推断出重叠区域中缺失的光,来实测尘埃消光,这是银河系研究中的一个关键干扰参数。然而,目前的重叠对目录在数量上相比专门针对单个星系的目录要有限。扩大这个目录不仅是为了促进进一步的详细尘埃研究,超越迄今为止有限的研究,而且也是为了改进对-对的方差并支持通过机器学习技术进行自动识别。为此,我们利用被分类为“重叠”的星系来自Galaxy Zoo DECaLS(GZD-1、-2和-5),以及DESI遗产调查数据释放10(DR10)中的图像,在我们的个人公民科学项目中直接对这些对进行分类。这个新的目录不仅将为未来的尘埃研究提供大量目标,还将有助于对这些对和尘埃本身有更深入的理解。

英文摘要:

Overlapping galaxies, in which a foreground galaxy partially overlaps a background galaxy, offer a unique opportunity to measure dust attenuation, a key nuisance parameter in galaxy studies, empirically and in great detail by modelling the light of both the foreground and background galaxy and inferring the missing light in the overlapping region. However, the current catalogue of overlapping pairs is relatively limited in number compared to catalogues dedicated to individual galaxies. Expanding this catalogue is not only a necessity to facilitate further detailed dust studies beyond the few limited studies conducted thus far, but also to improve pair-to-pair variance and support automated identification through machine learning techniques. To achieve this, we utilise galaxies classified as "overlapping" from Galaxy Zoo DECaLS (GZD-1, -2, and -5), along with images from Data Release 10 (DR10) of the DESI Legacy Survey, in our individual citizen science project to classify these pairs directly using volunteers. This new catalogue will not only provide a wealth of targets for future dust studies but will also contribute to a deeper understanding of these pairs and dust as a whole.
