摘要:

上下文在费米卫星运行的头两年产生的伽马射线源目录发布之后,相当一部分源仍然在较低的能量下没有关联。除了众所周知的高能发射体(超新星、耀变体、超新星遗迹等)理论上的期望预测了新的伽马射线源类别。特别是,伽马射线辐射可能与恒星演化的某些早期阶段有关,但这种有趣的可能性仍然知之甚少。目标。本文的目的是评估费米伽马射线源2FGL J0607.5- 0618 c与大质量恒星形成区麒麟座R2相关的可能性。方法.使用无线电、红外线、X射线和伽马射线波长的档案数据对Monoceros R2区域进行了多波长分析。由此产生的观测特性被用来估计测试不同物理场景所需的物理参数。结果我们确认2FGL J0607.5- 0618 c的检测与费米两年目录的置信度提高。我们发现,麒麟座R2中多个年轻恒星的综合效应是一个可行的图片的性质的来源。

英文摘要:

Context. After the release of the gamma-ray source catalog produced by the Fermi satellite during its first two years of operation, a significant fraction of sources still remain unassociated at lower energies. In addition to well-known high-energy emitters (pulsars, blazars, supernova remnants, etc.) theoretical expectations predict new classes of gamma-ray sources. In particular, gamma-ray emission could be associated with some of the early phases of stellar evolution, but this interesting possibility is still poorly understood. Aims. The aim of this paper is to assess the possibility of the Fermi gamma-ray source 2FGL J0607.5-0618c being associated with the massive star forming region Monoceros R2. Methods. A multi-wavelength analysis of the Monoceros R2 region is carried out using archival data at radio, infrared, X-ray, and gamma-ray wavelengths. The resulting observational properties are used to estimate the physical parameters needed to test the different physical scenarios. Results. We confirm the 2FGL J0607.5-0618c detection with improved confidence over the Fermi two-year catalog. We find that a combined effect of the multiple young stellar objects in Monoceros R2 is a viable picture for the nature of the source.
