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.

Gems of the Galaxy Zoos -- a Wide-Ranging Hubble Space Telescope Gap-Filler Program
我们描述了银河系动物园的宝石(动物园宝石)项目,一个填补空白的项目,在哈勃太空望远镜的时间表中使用短窗口。与以前的快照计划一样,目标是根据位置从一个池中提取的;我们结合了志愿者在银河动物园和无线电银河动物园公民科学项目中选择的对象。Zoo Gems使用Advanced Camera for Surveys(ACS)的曝光来解决星系形态,星际介质内容,活动星系核的宿主星系和星系演化等广泛的主题。科学案例包括研究星系的相互作用,星系中的背光尘埃,星暴后系统,环和特殊的螺旋图案,通常的颜色-形态关系的异常值,绿豆紧凑的星暴系统,螺旋宿主星系的双射电源,以及活动星系核周围的扩展发射线区域。对于这些科学类别中的许多类别,从更大的列表中最终选择目标是通过投票过程使用公众输入。到目前为止的亮点包括在蓝色的,显然是早期类型的星系中紧密缠绕的螺旋结构的流行,一个几乎完整的爱因斯坦环从一个群透镜,在较低的表面亮度周围的紧凑的绿豌豆星爆的红色组件,以及螺旋星系托管大型双射电源的高概率例子。
