## 0. Abstract
我們計劃使用契忍可夫望遠鏡陣列（CTA）對大麥哲倫星雲進行 ∼ 0.1−100 TeV 光子能量的深入調查。我們根據星系發射模型評估探測前景，該模型包括四個已知的 **TeV 發射源**（emitter）、**模擬源種群**（mock populations of sources）和**星系尺度的星際發射**（interstellar emission on galactic scales）。我們還評估了 [劍魚座 30](https://zh.wikipedia.org/wiki/%E8%9C%98%E8%9B%9B%E6%98%9F%E4%BA%91) 和 [SN 1987A](https://zh.wikipedia.org/wiki/SN_1987A) 的可探測性，以及可以得出的對暗物質性質的限制。該調查將允許對 [N 157B](http://tevcat.uchicago.edu/?mode=1;id=236)、[N 132D](http://tevcat.uchicago.edu/?mode=1;id=256)、[LMC P3](http://tevcat.uchicago.edu/?mode=1;id=304) 和 [劍魚座 30 C](http://tevcat.uchicago.edu/?mode=1;id=255) 進行精細的光譜研究，並且應該揭示六個其他來源，主要是脈衝星驅動的物體。 如果 SN 1987A 產生的宇宙射線核在高能量下具有平坦的冪律譜，或者俱有更陡峭的譜指數（2.3--2.4），等待通量在 ∼2015--2035 年內增加超過 3 至 4 倍時，就可以檢測到它的殘餘物。如果大於 10 GeV 的光譜具有軟光子譜指數 ∼ 2.7，則大尺度星際發射仍然大部分無法進行調查，但如果宇宙射線光譜硬化以上，則可以檢測到量級在 0.1--10 TeV 的 π 介子衰變發射 > 100 GeV。如果加速效率在機械光度的 1--10% 數量級，並且擴散在 < 100 pc 內被抑制兩個數量級，那麼劍魚座 30 的恆星形成區是可檢測的。 最後，該調查可以探測標準速度平均截面，用於尖點 [Navarro-Frenk-White 剖面](https://en.wikipedia.org/wiki/Navarro%E2%80%93Frenk%E2%80%93White_profile)的弱交互作用大質量粒子的自湮滅。
