大麦云云的费米观测
Fermi Observations of the Large Magellanic Cloud
摘要:
我们报告的观测大麦云与费米伽玛射线太空望远镜。大麦哲伦星系被大面积望远镜(LAT)清晰地探测到,并且第一次在伽马射线中得到了很好的空间分辨。我们的观测结果表明,大部分的伽马射线发射来自剑鱼座30区域。我们讨论了这一结果,在光的大规模的恒星人口,在这一领域的主机和宇宙射线物理解决的影响。最后,我们探讨了正在进行的费米观测的大质量恒星的高能现象的研究的科学潜力。
英文摘要:
We report on observations of the Large Magellanic Cloud with the Fermi Gamma-Ray Space Telescope. The LMC is clearly detected with the Large Area Telescope (LAT) and for the first time the emission is spatially well resolved in gamma-rays. Our observations reveal that the bulk of the gamma-ray emission arises from the 30 Doradus region. We discuss this result in light of the massive star populations that are hosted in this area and address implications for cosmic-ray physics. We conclude by exploring the scientific potential of the ongoing Fermi observations on the study of high-energy phenomena in massive stars.
