摘要
康普顿谱仪与成像仪（Compton Spectrometer and Imager，COSI）是一项选定的小型探测器（SMEX）任务，将于 2027 年发射。它由一个大视场康普顿望远镜组成，将以更高的灵敏度探测尚未充分探索的 MeV 伽马射线天空（0.2-5 MeV）。我们将介绍 cosipy 的当前状态，这是一个 Python 库，将执行光谱与偏振拟合、图像去卷积，以及 COSI 广泛科学目标所需的所有高层分析任务：揭示银河系正电子的起源、绘制银河系核合成位置、改进我们对伽马射线暴（GRBs）与活动星系核（AGNs）的喷流及发射机制的模型，并探测与定位引力波和微中子源。cosipy 库建立在 COSI 气球飞行活动所获得的经验之上，并将康普顿能区的数据分析带入现代开源基于似然的代码，能够使用多任务最大似然框架（3ML）与其他仪器进行相干联合拟合。在本报告中，我们还将讨论我们的计划：通过每年发布软件版本并配合公开可用的数据挑战来接收来自社区的反馈。
