Feature selection for classification of blazars
Read more »We characterize the variability of blazars using the Ornstein–Uhlenbeck (OU) process, and search for the features that are discriminative for the two subtypes, FSRQs and BL Lac objects.

Degeneracy of the SED Model of the blazar Mrk 421
Read more »The observed SEDs of blazars cannot determine all parameters of the synchrotron self-Compton model in most cases. We studied this problem in detail, and present the SED analysis of the blazar Mrk 421.

Optical polarization variations in the blazar PKS 1749+096
Read more »We report on the variation in the optical polarization of the blazar PKS 1749+096. The object favors a polarization angle (PA) of 40°-50° at the flare maxima. Three clear polarization rotations were detected.

Optical Observation of the 2003 Outburst of a Black Hole X-Ray Binary, V4641 Sagittarii
We report on the results of our optical photometric observations of a black hole X-ray binary, V4641 Sgr during an outburst in 2003 August.

Optical behavior of GRB 061121 around its X-Ray shallow decay phase
We report on a detailed study of the optical afterglow of GRB 061121 with our original time-series photometric data.

Doppler tomography by total variation minimization
We have developed a new model of Doppler tomography using total variation minimization (DTTVM). This method can reconstruct localized and …
