H.E.S.S.大麦云云观测
H.E.S.S. observations of the Large Magellanic Cloud
摘要：
大麦云云（LMC）是银河系的一个卫星星系，距离大约48千秒差距。尽管它的距离，它拥有几个有趣的目标TeV的伽马射线观测。复合超新星遗迹N 157 B/PSR J 05367 -6910是由H.E.S.S.发现的。它是极高能（VHE）伽马射线的发射器。它是迄今为止在VHE伽马射线中探测到的最远的脉冲星风星云。另一个非常令人兴奋的目标是SN 1987 A，它是最近发生在银河系附近的超新星爆炸的遗迹。这个遗迹中的宇宙射线加速模型预测，伽马射线发射的水平可以被H.E.S.S.探测到。但至今尚未发现。费米/LAT在剑鱼座30的大质量恒星形成区发现了弥漫的高能伽马射线辐射，但没有明确的证据表明N 157 B或SN 1987 A有辐射。包含这些物体的LMC部分一直由H.E.S.S.定期观察。自2003年以来的望远镜。在2010年进行的深度观测中，已经获得了这部分天空的非常好的曝光。H.E.S.S.的现状LMC的观测结果与N 157 B和SN 1987 A的新结果一起报告。
英文摘要：
The Large Magellanic Cloud (LMC) is a satellite galaxy of the Milky Way at a distance of approximately 48 kpc. Despite its distance it harbours several interesting targets for TeV gamma-ray observations. The composite supernova remnant N 157B/PSR J05367-6910 was discovered by H.E.S.S. being an emitter of very high energy (VHE) gamma-rays. It is the most distant pulsar wind nebula ever detected in VHE gamma-rays. Another very exciting target is SN 1987A, the remnant of the most recent supernova explosion that occurred in the neighbourhood of the Milky Way. Models for Cosmic Ray acceleration in this remnant predict gamma-ray emission at a level detectable by H.E.S.S. but this has not been detected so far. Fermi/LAT discovered diffuse high energy (HE) gamma-ray emission from the general direction of the massive star forming region 30 Doradus but no clear evidence for emission from either N 157B or SN 1987A has been published. The part of the LMC containing these objects has been observed regularly with the H.E.S.S. telescopes since 2003. With deep observations carried out in 2010 a very good exposure of this part of the sky has been obtained. The current status of the H.E.S.S. LMC observations is reported along with new results on N 157B and SN 1987A.
