我们提出银河动物园装饰:SDSS DR 8足迹内星系的暗能量相机遗产调查图像的详细视觉形态分类。更深的DECaLS图像(r=23.6与SDSS的r=22.2)显示了螺旋臂、弱条和以前在SDSS成像中不可见的潮汐特征。为了最好地利用DECaLS图像的更大深度,志愿者从一组新的答案中选择,这些答案旨在提高我们对合并和酒吧的敏感性。银河动物园志愿者提供了超过314,000个星系的750万个分类。140,000个星系至少有30个分类,足以精确测量像条形图这样的详细形态,其余的大约有5个。所有分类都用于训练贝叶斯卷积神经网络(一种最先进的深度学习方法),以预测所有314,000个星系的详细形态的后验。当与自信的志愿者分类进行衡量时,网络对每个问题的准确率约为99%。形态学是每个星系的基本特征;我们的人类和机器分类是了解星系如何演化的准确而详细的资源。
英文摘要:
We present Galaxy Zoo DECaLS: detailed visual morphological classifications for Dark Energy Camera Legacy Survey images of galaxies within the SDSS DR8 footprint. Deeper DECaLS images (r=23.6 vs. r=22.2 from SDSS) reveal spiral arms, weak bars, and tidal features not previously visible in SDSS imaging. To best exploit the greater depth of DECaLS images, volunteers select from a new set of answers designed to improve our sensitivity to mergers and bars. Galaxy Zoo volunteers provide 7.5 million individual classifications over 314,000 galaxies. 140,000 galaxies receive at least 30 classifications, sufficient to accurately measure detailed morphology like bars, and the remainder receive approximately 5. All classifications are used to train an ensemble of Bayesian convolutional neural networks (a state-of-the-art deep learning method) to predict posteriors for the detailed morphology of all 314,000 galaxies. When measured against confident volunteer classifications, the networks are approximately 99% accurate on every question. Morphology is a fundamental feature of every galaxy; our human and machine classifications are an accurate and detailed resource for understanding how galaxies evolve.

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。
