JWST 银河系中心巡天——一份白皮书

摘要
银河系内百秒差距区域拥有最近的超大质量黑洞、最大的致密气体储库、最高的恒星密度、数百颗大质量主序和主序后恒星，以及银河系中最高的超新星体积密度。作为最近的可同时观测塑造宇宙的诸多极端过程的环境，它成为天体物理学中研究最充分的区域之一。由于其邻近性，我们能在低至几百 AU 的尺度上研究银河系中心，比类似的本星系群星系好一百倍，比最近的活跃星系好几千倍。因此银河系中心（GC）具有杰出的天体物理意义。然而，尽管过去几十年进行了密集的观测工作，关于 GC 仍有基本的未知事物。JWST 具有提供必要且改变格局的数据的独特能力。在本白皮书中，我们倡导一项 JWST NIRCam 巡天，旨在解决我们作为学界所确认的核心问题：i）气体与恒星的三维结构与运动学；ii）古老恒星形成及其与银河系整体历史的关系，以及近期恒星形成及其对我们星系核整体能量的影响；iii）恒星形成的（非）普适性与恒星初始质量函数。我们倡导以面向学界开放的 Treasury GO JWST 大计划形式，对星系内 100\,pc 区域开展大面积、多历元、多波长 NIRCam 巡天。我们描述了该巡天将如何推导约 10,000,000 颗恒星的物理和运动学性质，将如何解决关键未知问题，并提供具有长久遗留价值的宝贵学界资源。
