Supernova Hunters 分類記録Supernova Hunters: classification record

Zooniverse · Pan-STARRS1 · 2017年・2020年2017 and 2020

Supernova Hunters は Zooniverse の市民科学プロジェクトで、ボランティアが Pan-STARRS1 の差分画像で検出された天体を見て、本物の突発天体か偽検出かを判定します(Wright et al. 2017; Pan-STARRS1 については Chambers et al. 2016)。私は2017年(ユーザー名 Sting1)と2020年に分類に参加しました。プロジェクトの記録では、Transient Name Server(TNS)に報告された27個の突発天体の分類者に含まれており、うち2個は分光観測で Ia型超新星と確認されています。Supernova Hunters is a Zooniverse project in which volunteers inspect Pan-STARRS1 (Chambers et al. 2016) difference-imaging detections and mark each as a real transient or an artefact (Wright et al. 2017). I took part as a classifier in 2017 (as Sting1) and in 2020. The project lists me among the classifiers of 27 transients reported to the Transient Name Server (TNS); two have been confirmed spectroscopically as Type Ia supernovae.
