Double-peaked Ca II traces a relativistic broad-line region disk in NGC 4593
M. W. Ochmann, P. M. Weilbacher, M. A. Probst +7
Double-peaked emission lines are observed in a small percentage of active galactic nuclei (AGN). These lines allow the determination of properties of the line-emitting region, know…
Broad-Line Region Characterization in Dozens of Active Galactic Nuclei Using Small-Aperture Telescopes
Catalina Sobrino Figaredo, Doron Chelouche, Martin Haas +9
We present the results of a nearly decade-long photometric reverberation mapping (PRM) survey of the H emission line in nearby () Seyfert-Galaxies u…
The transient event in NGC 1566 from 2017 to 2019 -- I. An eccentric accretion disk and a turbulent, disk-dominated broad-line region unveiled by double-peaked Ca II and O I lines
M. W. Ochmann, W. Kollatschny, M. A. Probst +12
NGC 1566 is known for exhibiting recurrent outbursts, which are accompanied by changes in spectral type. The most recent transient event occurred from 2017 to 2019 and was reported…
Dust emission from 3C radio galaxies and quasars: New ISO observations favour the unified scheme
K. Meisenheimer, M. Haas, S. A. H. Müller +3
In order to test the unified scheme for luminous radio galaxies and quasars we observed 10 galaxy/quasar pairs from the 3CR catalogue with ISOPHOT at infrared wavelengths between 5…
