-band host galaxy contamination of TeV -ray blazar Mrk 501: effects of the aperture size and seeing
Hai-Cheng Feng, Hong-Tao Liu, Ying-He Zhao +3
We simulated the -band contribution of the host galaxy of TeV -ray BL Lac object Mrk 501 in different aperture sizes and seeing conditions . The intensive observations were r…
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…
The possible submillimeter bump and accretion-jet in the central supermassive black hole of NGC 4993
Qingwen Wu, Jianchao Feng, Xuliang Fan
NGC 4993, as a host galaxy of the electromagnetic counterpart of the first gravitational-wave detection of a binary neutron-star merger, was observed by many powerful telescopes fr…
Search for intra-day optical variability in Mrk 501
Hai-Cheng Feng, H. T. Liu, X. L. Fan +5
We present our observations of the optical intra-day variability (IDV) in -ray BL Lac object Mrk 501. The observations were run with the 1.02 m and 2.4 m optical telescopes at Y…
