Reverberation Mapping of Changing-look Active Galactic Nucleus NGC 3516
Hai-Cheng. Feng, Chen. Hu, Sha-Sha. Li +7
The changes of broad emission lines should be a crucial issue to understanding the physical properties of changing-look active galactic nucleus (CL-AGN). Here, we present the resul…
Evidence for Two Distinct Broad-Line Regions from Reverberation Mapping of PG 0026+129
Chen Hu, Sha-Sha Li, Wei-Jian Guo +17
We report on the results of a new spectroscopic monitoring campaign of the quasar PG 0026+129 at the Calar Alto Observatory 2.2m telescope from July 2017 to February 2020. Signific…
Spectroscopic Monitoring of Blazar S5 0716+714: Brightness-Dependent Spectral Behavior
Hai-Cheng Feng, Sen. Yang, Zi-Xu. Yang +17
In this paper, we report the new results of spectroscopic observations of -ray blazar S5 0716+714 from 2019 September to 2020 March with the 2.4 m optical telescope at Lijiang O…
Mapping the magnetic field in the solar corona through magnetoseismology
Zihao Yang, Hui Tian, Steven Tomczyk +4
Magnetoseismology, a technique of magnetic field diagnostics based on observations of magnetohydrodynamic (MHD) waves, has been widely used to estimate the field strengths of oscil…
Global maps of the magnetic field in the solar corona
Zihao Yang, Christian Bethge, Hui Tian +10
Understanding many physical processes in the solar atmosphere requires determination of the magnetic field in each atmospheric layer. However, direct measurements of the magnetic f…
