Revisiting Emission-Line Measurement Methods for Narrow-Line Active Galactic Nuclei
Viraja C. Khatu, Sarah C. Gallagher, Keith Horne +16
Measuring broad emission-line widths in active galactic nuclei (AGN) is not straightforward owing to the complex nature of flux variability in these systems. Line-width measurement…
Supermassive Black Hole and Broad-line Region in NGC~5548: Results from Five-season Reverberation Mapping
Kai-Xing Lu, Jin-Ming Bai, Jian-Min Wang +9
NGC 5548 is one of the active galactic nuclei (AGN) selected for our long-term spectroscopic monitoring with the Lijiang 2.4~m telescope, aiming at investigating the origin and evo…
A High-Quality velocity-delay map of the broad-line region in NGC 5548
Ming Xiao, Pu Du, Kai-Xing Lu +10
NGC 5548 has been well spectroscopically monitored for reverberation mapping of the central kinematics by 19 campaigns. Using the maximum entropy method in this Letter, we build up…
Diversity of multiwavelength emission bumps in the GRB 100219A afterglow
J. Mao, D. Malesani, P. D'Avanzo +4
Context. Multi-wavelength observations of gamma-ray burst (GRB) afterglows provide important information about the activity of their central engines and their environments. In part…
Absorption of 10--200 Gev Gamma Rays by Radiation from BLR in Blazars
H. T. Liu, J. M. Bai
In this paper, we study the photon-photon pair production optical depth for gamma-rays with energies from 10 to 200 GeV emitted by powerful blazars due to the diffuse radiation fie…
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…
