内容：磁星是一种极端的、高度磁化的孤立中子星，其巨大的X射线光度被认为是由其高磁场驱动的。目的：我们首次研究了磁星可能的100 GeV以上的甚高能量γ射线发射，观测了源4U 0142+61和1 E 2259+586。方法：用大气切伦科夫望远镜在极高能区（E > 100 GeV）对这两个源进行观测。2008年用MAGIC I望远镜对4U 0142+61进行了约25 h的观测，2010年用MAGIC立体系统对1 E 2259+586进行了约14 h的观测。用标准MAGIC分析软件分析数据。结果：两颗磁星均未检出。上限的微分和积分通量超过200 GeV的计算使用Rolke算法。在95%的置信水平下，我们得到4U 0142+61和1 E 2259+586的通量积分上限分别为1.52 × 10 - 12 cm-2 s-1和2.7 × 10-12 cm-2 s-1。由此产生的微分上限与X射线数据和上限在GeV的能量范围内。
Context: Magnetars are an extreme, highly magnetized class of isolated neutron stars whose large X-ray luminosity is believed to be driven by their high magnetic field. Aims: We study for the first time the possible very high energy γ-ray emission above 100 GeV from magnetars, observing the sources 4U 0142+61 and 1E 2259+586. Methods: We observed the two sources with atmospheric Cherenkov telescopes in the very high energy range (E > 100 GeV). 4U 0142+61 was observed with the MAGIC I telescope in 2008 for about 25 h and 1E 2259+586 was observed with the MAGIC stereoscopic system in 2010 for about 14 h. The data were analyzed with the standard MAGIC analysis software. Results: Neither magnetar was detected. Upper limits to the differential and integral flux above 200 GeV were computed using the Rolke algorithm. We obtain integral upper limits to the flux of 1.52 × 10-12 cm-2 s-1 and 2.7 × 10-12 cm-2 s-1 with a confidence level of 95% for 4U 0142+61 and 1E 2259+586, respectively. The resulting differential upper limits are presented together with X-ray data and upper limits in the GeV energy range.
