| Abstract: | Recent progress in the X-ray study of TeV blazars observed with ASCA,RXTE,Beppo SAX,and XMM-NEWTON is reviewed in this paper.The most important aspects emerged from the temporal and spectral analysis of the X-ray data,including power spectral density,structure function,inter-band time lags,shifts of synchrotron peak energies,and spectral evolution are focused.The physical implications inferred from these new results are also briefly discussed. |
