Beginning of ReadMe : J/other/NewA/11.557 Infrared photometry of BL Lac objects (Chen+, 2006) ================================================================================ On the difference between the X-ray selected and the radio selected BL Lac objects in the near infrared. Chen P.S., Shan H.G., Gao Y.F. <New Astronomy, 11, 557-566 (2006)> =2006NewA...11..557C ================================================================================ ADC_Keywords: BL Lac objects ; Infrared sources ; Photometry, infrared Keywords: galaxy: AGN, BL Lac object - infrared: galaxy Abstract: 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 in the near infrared than XBLs, whereas the XBLs have more influences from their host galaxies than the RBLs. It is also seen that the RBLs have much brighter luminosity in the near infrared than the XBLs. In addition, the high polarization characteristics are found in common for RBLs, but not for XBLs.
