PHANGS-JWST：数据处理管线与首次完整公开数据发布
摘要
JWST 精湛的角分辨率和灵敏度正在为我们理解宇宙打开一扇新窗口。在邻近星系中，JWST 观测正在彻底改变我们对恒星形成最初阶段和充满尘埃的星际介质的理解。作为 PHANGS-JWST Cycle 1 Treasury 程序的一部分，已对横跨恒星形成主序的一系列性质和形态的 19 个本星系群进行了空间尺度约为 5-50pc 的观测。在此，我们描述了 pjpipe，这是一个为 PHANGS-JWST 程序开发的图像处理管线，它封装并扩展了官方 JWST 管线。我们向社区发布此管线，因为它包含许多对 JWST NIRCam 和 MIRI 观测普遍有用的工具。特别是对于延展源，在消除 NIRCam 数据中的仪器噪声、背景通量匹配以及相对和绝对天体测量校准方面，pjpipe 产品相比 MAST 档案的马赛克图像有显著改进。我们证明，将 F2100W MIRI 数据稍微平滑至 0.9"（分辨率降低约 30%）可将噪声降低约 3 倍。我们还展示了 PHANGS-JWST Cycle 1 Treasury 程序中所有 19 个星系的 pjpipe 处理的八波段 2-21 m 成像的首次公开发布（DR1.1.0）。来自新的 PHANGS-JWST Cycle 2 Treasury 程序的另外 55 个星系即将跟进。
