X-ray variability in high energy peaked BL Lac objects (HBLs) is characterized by a correlation between flux and index and by soft lag. It is shown that these properties can quantitatively be expressed by Fermi acceleration and synchrotron cooling model and physical parameters in accelerating and de

By using results from the 2MASS observation, the differences between the X-ray selected BL Lac objects (XBLs) and the radio selected ones (RBLs) in the near infrared are discussed in this paper. It is found that, statistically, the RBLs have redder near infrared colors and steeper spectral indices i
