| 4 | Mrk421中TeV和X射线爆发的相关性显示文摘用同步自康普顿机制(SSC)来解释1994年5月在BLLac天体Mrk421中观测到的TeVX射线爆发.认为此TevX射线爆发是由一个高能成分产生的,它具有平坦的电子能量分布,其低能段上能谱指数αe≈025.这个爆发成分独立于另一个低能成分(或宁静成分).此宁静成分具有较陡的电子能量分布,它产生宁静态的辐射能谱.大多数射电爆发表明电子能量分布有坦谱,能谱指数αe~02-04.与这个事实一起,上述结果意味着活动星系核中粒子加速的基本机制产生平坦的电子能量分布. | 张喜镇 A.Witzel T.Krichbaum S.Britzen A.Kraus | 1998 | 天体物理学报1998，18，1： | 0 |
| 5 | Multifrequency Polarization Variations in the Quasar 0917+624显示文摘We present a detailed analysis of multi-frequency observations of linear polarization in the intraday variable quasar 0917+624 (z = 1.44). The observations were made in May 1989 at five frequencies (1.4, 2.7, 5.0, 8.3 and 15 GHz) with the VLA and the Effelsberg 100m-telescope and in December 1988 at two frequencies (2.7 and 5.0 GHz) with the latter. It is shown that the relationship between the variations of the polarized and total flux density is highly wavelength dependent,and the multi-frequency polarization behavior may be essential for investigating the mechanisms causing these variations. It is shown that the variations observed at 20cm can be interpreted in terms of refractive interstellar scintillation. However,light-curve of the polarized flux density, indicating an additional variable component. Interestingly, these features are shown to be correlated with the variations at 2-6 cm, thus indicating that these features and the associated variations are due to some intrinsic causes. Moreover, a very rapid polarization angle swing of ~ 180°observed in December 1988 which cannot be explained by refractive interstellar scintillation, may also be produced by an intrinsic mechanism. Accordingly, we use a shock model to explain the polarization variations observed at the higher frequencies, although scintillation could also exist. The shock model can explain not only the variation of intensity, but also the time variation of its degree and angle of polarization, including the rapid swing of the polarization angle. It is shown that the degree and angle of polarization of the shock need only vary slightly in order to account for the observed complicated behaviour of polarization. | Shan-JieQian A.Kraus 等 | 2002 | Chinese Journal of Astronomy and Astrophysics2002，2，4： | 0 |
| 6 | Interstellar Refractive Scintillation and Intraday Polarization Angle Swings显示文摘Intraday polarization angle swings of ~180° observed in two sources (QSO 0917+624 and QSO 1150+812) are discussed in the framework of refractive interstellar scintillation by a continuous interstellar medium. Model-fits to the I-,Q- and U- light curves were made for both sources. It is shown that for the case of 0917+624 both the intraday intensity variations and the polarization angle swing of ~180° could be explained consistently in terms of a four-component model, which comprises one steady and two scintillating polarized components and one further non-polarized scintillating component. The polarization angle swing of ~180° observed in 1150+812, which occurred when the polarized flux density was almost constant, could not be explained in terms of refractive scintillation by a continuous medium and might be due to other mechanisms (e.g., scintillation by interstellar clouds). | Shan-JieQian Xi-ZhenZhang A.Kraus | 2005 | Chinese Journal of Astronomy and Astrophysics2005，5，1： | 0 |
