| Research Abstract |
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.
