在高功率雷达和甚高能量gamma-ray源之间建立连接

Establishing a connection between high-power pulsars and very-high-energy gamma-ray sources

摘要:

在甚高能(VHE)伽马射线波段,脉冲星风星云(PWNe)是迄今为止数量最多的银河系源。尽管如此,在中子星附近的能量转换机制的细节还没有很好的理解,也不知道哪些中子星能够驱动PWNe并发射高能辐射。在本文中,我们提出了一个系统的研究之间的联系,VHE伽马射线源的基础上进行的高能立体系统(H.E.S.S.)的银河系内平面的深调查。我们发现了明确的证据,大自旋下的能量通量的恒星与VHE伽马射线源。这意味着这些类星体以TeV伽马射线的形式发射出大约1%的自旋向下能量。

英文摘要:

In the very-high-energy (VHE) gamma-ray wave band, pulsar wind nebulae (PWNe) represent to date the most populous class of Galactic sources. Nevertheless, the details of the energy conversion mechanisms in the vicinity of pulsars are not well understood, nor is it known which pulsars are able to drive PWNe and emit high-energy radiation. In this paper we present a systematic study of a connection between pulsars and VHE gamma-ray sources based on a deep survey of the inner Galactic plane conducted with the High Energy Stereoscopic System (H.E.S.S.). We find clear evidence that pulsars with large spin-down energy flux are associated with VHE gamma-ray sources. This implies that these pulsars emit on the order of 1% of their spin-down energy as TeV gamma-rays.
