A Method for Locating High Energy Dissipation Region in Blazar
Dahai Yan, Qingwen Wu, Xuliang Fan +2
The production site of gamma-rays in blazar jet is an unresolved problem. We present a method to locate gamma-ray emission region in the framework of one-zone emission model. From…
Constraints on the location of -ray emitting region for a sample of blazars with radio core-shift measurements
Linhui Wu, Qingwen Wu, Dahai Yan +2
We model simultaneous or quasi-simultaneous multi-band spectral energy distributions (SEDs) for a sample of 25 blazars that have radio core-shift measurements, where a one-zone lep…
Constraining the redshifts of TeV BL Lac objects
Longhua Qin, Jiancheng Wang, Dahai Yan +3
We present a model-dependent method to estimate the redshifts of three TeV BL Lac objects (BL Lacs) through fltting their (quasi-) simultaneous multi-waveband spectral energy distr…
A -ray Quasi-Periodic modulation in the Blazar PKS 0301243?
Peng-Fei Zhang, Da-Hai Yan, Jia-Neng Zhou +3
We report a nominally high-confidence -ray quasi-periodic modulation in the blazar PKS 0301243. For this target, we analyze its \emph{Fermi}-LAT Pass 8 data covering from 200…
Possible Quasi-Periodic modulation in the z = 1.1 -ray blazar PKS 0426-380
Pengfei Zhang, Dahai Yan, Nenghui Liao +3
We search for -ray and optical periodic modulations in a distant flat spectrum radio quasar (FSRQ) PKS 0426-380 (the redshift ). Using two techniques (i.e., the maximum l…
