An Automatic Approach for Grouping Sunspots and Calculating Relative Sunspot Number on SDO/HMI Continuum Images
Cui Zhao, Shangbin Yang, Tingmei Wang +4
Relative Sunspot Number is one of the major parameters for the study of long-term solar activity. The automatic calculation of the Relative Sunspot Number is more stable and accura…
The size of BLRs of low luminous Active Galactic Nuclei
Zhang Xue-Guang, Deborah Dultzin-Hacyan, Wang Ting-Gui
We study the size of BLRs of low luminosity Active Galactic Nuclei, also called 'dwarf AGN', defined as having ()). We more than double the s…
Active Galaxies in the UV
Wolfram Kollatschny, Wang Ting-Gui
In this article we present different aspects of AGN studies demonstrating the importance of the UV spectral range. Most important diagnostic lines for studying the general physical…
The Nature of the Broad--Line--Region in the Radio--Loud AGN 3C390.3
Willem Wamsteker, Wang Ting-gui, Norbert Schartel +1
We present an analysis of the ultraviolet and X-Ray variability of the Broad- Line-Radio Galaxy 3C390.3 over 15 years. The UV continuum showed large variations with amplitudes of u…
