用MAGIC望远镜观测活动星系核的科学亮点
Scientific Highlights from Observations of Active Galactic Nuclei with the MAGIC Telescope
摘要:
自2004年以来,MAGIC伽马射线望远镜新发现了6 TeV的耀变体。MAGIC探测到的13个活动星系核包括其他波长的研究对象,如Markarian 501和巨型射电星系M87,以及遥远的平谱射电类星体3C 279和新发现的TeV伽马射线发射体S5 0716+71。此外,还对已知的TeV耀变体进行了长期和多波长的研究,并对新的TeV耀变体进行了系统的搜索。在这里,我们报告了最近MAGIC对河外TeV伽马射线源的观测结果,强调了MAGIC能够做出的新物理见解。
英文摘要:
Since 2004, the MAGIC gamma-ray telescope has newly discovered 6 TeV blazars. The total set of 13 MAGIC-detected active galactic nuclei includes well-studied objects at other wavelengths like Markarian 501 and the giant radio galaxy M87, but also the distant the flat-spectrum radio quasar 3C 279, and the newly discovered TeV gamma-ray emitter S5 0716+71. In addition, also long-term and multi-wavelength studies on well-known TeV blazars and systematic searches for new TeV blazars have been carried out. Here we report selected highlights from recent MAGIC observations of extragalactic TeV gamma-ray sources, emphasizing the new physics insights MAGIC was able to contribute.
