What ZTF Saw Where Rubin Looked: Anomaly Hunting in DR23
Year: 2025
Type: article
Abstract: We present results from the SNAD VIII Workshop, during which we conducted the first systematic anomaly search in the Zwicky Transient Facility fields also observed by LSST commissioning camera during Rubin Scientific Pipeline commissioning. Using the PineForest active anomaly detection (AD) 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 AD pipeline and provide a preview of the discovery potential in the upcoming LSST data.
