Euclid: An automated system to match Rubin transient alerts to Euclid observations
AI总结：
Euclid系统通过自动匹配Rubin暂现警报与Euclid观测，提升暂现源检测和超新星时间约束，以及宿主形态测量精度。
AI中文摘要：
Vera C. Rubin天文台预计每晚会产生1000万条ugrizy波段的暂现警报，而Euclid是一台可见光至近红外空间望远镜，正在进行广角巡天。我们提出了一套原型系统，用于自动将Rubin的暂现警报与Euclid观测匹配。该系统生成包含可见光和近红外光度计的联合光变曲线以及联合图像裁剪。使用Zwicky暂现设施警报作为Rubin的代理，我们展示了该系统在Euclid检测到和未检测到暂现警报的情况下的应用，并突显了每种情况下的价值。对于被Euclid检测到的暂现源，这些好处包括在地面观测之前确定超新星（SNe）在观测中的位置，从而更好地约束爆炸时间，例如SN 2024pvw在地面检测之前约3天被检测到。在Euclid未检测到暂现源的情况下，我们展示了添加Euclid观测以提高宿主形态测量和关联的好处。
英文摘要：
The Vera C. Rubin observatory is expected to produce 10 million transient alerts per night in ugrizy filters, whilst Euclid is a visible to near-infrared space telescope engaged in a wide field survey. We present a prototype system to automatically match the transient alerts from Rubin to Euclid observations. The system produces joint light-curves containing both visible and near-infrared photometry, and joint image cutouts. Using Zwicky Transient Facility alerts as a proxy for Rubin, we demonstrate the system in use in cases where Euclid did and did not detect the transient and highlight the value that can be added in each case. For transients detected by Euclid these benefits include identifying the supernovae (SNe) in observations taken prior to ground-based detection, thereby better constraining the explosion time, such as SN 2024pvw detected ~3 d prior to ground based detections. In cases where Euclid did not detect the transient, we demonstrate the benefit of adding Euclid observations to improve host morphology measurements and associations.
