摘要
BL Lacertae objects(BL Lacs) are the dominant population of Te V emitting blazars. In this work, we investigate whether there are any special observational properties associated with Te V sources.To do so, we will compare the observational properties of Te V detected BL Lacs(Te V BLs) with non-Te V detected BL Lac objects(non-Te V BLs). From the 3rd Fermi/LAT source catalog(3FGL), we can obtain662 BL Lacs, out of which 47 are Te V BLs and 615 are non-Te V BLs. Their multi-wavelength flux densities(FpR, FO, FX and Fγ), photon spectral indexes(α^(ph)_Xand α^(ph)_γ), and effective spectral indexes(α_(RO) and α_(OX))are compiled from the available literature. Then the luminosities(log ν L_R, log ν L_O, log ν L_X, log ν L_γ)are calculated. From comparisons, we find that Te V BLs are different from low synchrotron peaked BLs and intermediate synchrotron peaked BLs, but Te V BLs show similar properties to high synchrotron peaked(HSP) BLs. Therefore, we concentrated on a comparison between Te V HSP BLs and non-Te V HSP BLs.Analysis results suggest that Te V HSP BLs and non-Te V HSP BLs exhibit some differences in their αRO and αphγ, but their other properties are quite similar.

Then the luminosities（log ν LR, log ν LO, log ν LX, log ν Lγ）are calculated. From comparisons, we find that Te V BLs are different from low synchrotron peaked BLs and intermediate synchrotron peaked BLs, but Te V BLs show similar properties to high synchrotron peaked（HSP） BLs. Therefore, we concentrated on a comparison between Te V HSP BLs and non-Te V HSP BLs.Analysis results suggest that Te V HSP BLs and non-Te V HSP BLs exhibit some differences in their αRO and αphγ, but their other properties are quite similar.
