The broad line region and dust torus structure of the Seyfert 1 WPVS48
C. Sobrino Figaredo, F. Pozo Nuñez, M. Ramolla +5
Optical and near-mid-infrared reverberation mapping data obtained at Universitätssternwarte Bochum in Chile and with the Spitzer Space Telescope allow us to explore the geometry of…
Simultaneous H alpha and dust reverberation mapping of 3C120: Testing the bowl-shaped torus geometry
Michael Ramolla, Martin Haas, Christian Westhues +8
At the Universitaetssternwarte Bochum near Cerro Armazones we have monitored the Seyfert-1 galaxy 3C 120 between September 2014 and March 2015 in BVRI and a narrow band filter cove…
Long-term optical, UV, and X-ray continuum variations in the changing-look AGN HE 1136-2304
M. Zetzl, W. Kollatschny, M. W. Ochmann +6
A strong outburst in the X-ray continuum and a change of its Seyfert spectral type was detected in HE 1136-2304 in 2014. The spectral type changed from nearly Seyfert 2 type (1.95)…
