Research on particle acceleration by X-ray observations of dark accelerators

在银道平面上有许多TeV伽玛射线天体，它们的起源还不清楚。它们被称为“暗粒子加速器”，因为伽马射线是高能粒子存在的直接证据。我们对暗粒子加速器进行了系统的x射线研究。我们发现了一些暗粒子加速器对应的暗x射线。对应物的暗淡告诉我们很少有高能电子。因此，伽马射线的起源可能是高能质子，而暗粒子加速器可能是宇宙射线的发源地。一些暗粒子加速器被认为与产生异常x射线脉冲星的一类特殊超新星或异常x射线明亮但非常致密的脉冲星风星云在物理上有关。

There are many TeV gamma-ray objects whose origins are not clarified along the Galactic plane. They are called “dark particle accelerators”, since the gamma-rays are direct evidence of the existence of high-energy particles. We have conducted systematic X-ray studies of the dark particle accelerators. We found dim X-ray counterparts to some of the dark particle accelerators. The dimness of the counterparts tells us that there are few high-energy electrons. Therefore the origin of the gamma-rays is probably high-energy protons, and the dark particle accelerators would be a birth place of the cosmic rays. Some of the dark particle accelerators are suggested to physicall y related to a special class of supernovae that produce anomalous X-ray pulsars or to an anomalously X-ray bright but very compact pulsar wind nebula.
