含MAGIC的混合物的上限(2005/2006年观察结果)

Upper limits for pulsars with MAGIC (2005/2006 observations)

R. De los Reyes, W. Bednarek, M. Camara, M. Lopez

摘要:

在过去的4年中,MAGIC合作已经寻找了一些最有希望的脉冲星候选者的高能伽马射线发射。MAGIC的低能量阈值为高灵敏度搜索提供了机会,该搜索仅高于50-100 GeV(自2008年以来,新的触发系统已将能量阈值降至25 GeV),这是迄今为止地面仪器和过去的卫星探测器无法到达的能量区域。在2005-2006年的观测活动中,没有从任何观测到的脉冲星上探测到脉冲伽马射线发射。本文给出了两个典型的超新星(PSR J 0205 +6449和PSR J2229+6114)及其宿主星云(分别为3C 58和Boomerang)和毫秒脉冲星PSR J 0218 +4232的上限。将讨论物理影响。

英文摘要:

During the last 4 years the MAGIC collaboration has searched for high-energy gamma-ray emission of some of the most promising pulsar candidates. The low energy threshold of MAGIC offered the opportunity for a high sensitivity search just above 50-100 GeV (since 2008 a new trigger system has decreased the energy threshold to 25 GeV), an energy region up to now not reachable to ground based instruments and past satellite borne detectors. No pulsed gamma-ray emission has been detected from any pulsar observed during the observation campaigns of 2005-2006. Here we present the upper limits obtained for tow canonical pulsars (PSR J0205+6449 and PSR J2229+6114) and their host nebulae (3C 58 and Boomerang, respectively) and the millisecond pulsar PSR J0218+4232. Physics implications will be discussed.
