WEBT and XMM-Newton observations of 3C 454.3 during the post-outburst phase. Detection of the little and big blue bumps
C. M. Raiteri, M. Villata, V. M. Larionov +3
The blazar 3C 454.3 underwent an unprecedented optical outburst in spring 2005. This was first followed by a mm and then by a cm radio outburst, which peaked in February 2006. We r…
Optical observations of BL Lacertae from 1997 to 1999
J. H. Fan, B. C. Qian, J. Tao
We present the optical (V, R, and I) photometry for BL Lacertae, which was observed from 1997 through 1999, with the 1.56-m telescope at the Shanghai astronomical observatory (SHAO…
The Radio and Gamma-Ray Luminosities of Blazars
L. Zhang, K. S. Cheng, J. H. Fan
Based on the -ray data of blazars in the third EGRET catalog and radio data at 5 GHz, we studied the correlation between the radio and -ray luminosities using two statistical…
Infrared Variation of Blazars
J. H. Fan
In this paper, the historical infrared (JHK) data compiled from the published literature are presented here for 30 blazars. Maximum near-IR variations are found and compared with t…
BL Lac Objects and Relativistic Beaming Model
J. H. Fan
In this paper: 1. The assumption of the dependence of Doppler factor on the emission frequency (Fan et al. 1993) is used to explain the observational differences between the radio-…
The infrared and optical variability of OJ 287
J. H. Fan, G. Adam, G. Z. Xie +7
In this paper, the long-term historical optical (UBVRI) and near-infrared (JHK) data are presented with some new observations in the optical (February 1994-January 1995) and near-i…
