Constraining broad-line regions from time lags of broad emission lines relative to radio emission
H. T. Liu, J. M. Bai, J. M. Wang +1
In this paper, a new method is proposed to estimate the broad-line region sizes of UV lines . It is applied to 3C 273. First, we derive the time lags of rad…

Locating positions of γ-ray--emitting regions in blazars
H. T. Liu, J. M. Bai, J. M. Wang
We propose a new method to locate the gamma-ray--emitting positions R_g from the measured time lags T_ob of gamma-ray emission relative to broad emission lines. The method is also…
