用异常检测发现6颗新变星，预示未来大规模巡天潜力。
What ZTF Saw Where Rubin Looked: Anomaly Hunting in DR23
- 结合ZTF与鲁宾望远镜数据，用主动异常检测算法筛查四片区域
- 发现6颗未收录的变星，6个已知天体分类和周期被修正
- 为后续大规模巡天中的异常天体发现提供验证范例
我们报告了SNAD VIII研讨会的结果，在此期间首次对鲁宾望远镜科学管道调试阶段观测到的ZTF区域进行了系统性异常搜索。利用PineForest主动异常检测算法，分析了四个选定区域（两个银河系内、两个银河系外），并人工检查了400个候选天体。结果发现了6颗此前未收录的变星，包括RS CVn型、BY Draconis型、椭球形及太阳型变星，并对6个已知天体的分类和周期进行了修正。这些成果展示了SNAD异常检测流程的有效性，也为即将到来的LSST数据中的发现潜力提供了预览。
原文摘要 · Abstract (English)
We present results from the SNAD VIII Workshop, during which we conducted the first systematic anomaly search in the ZTF fields also observed by LSSTComCam during Rubin Scientific Pipeline commissioning. Using the PineForest active anomaly detection algorithm, we analysed four selected fields (two galactic and two extragalactic) and visually inspected 400 candidates. As a result, we discovered six previously uncatalogued variable stars, including RS~CVn, BY Draconis, ellipsoidal, and solar-type variables, and refined classifications and periods for six known objects. These results demonstrate the effectiveness of the SNAD anomaly detection pipeline and provide a preview of the discovery potential in the upcoming LSST data.
