Seyfert 2 galaxies with unusually wide nebular lines
Hartmut Winkler, Trevor Chauke
We report on a set of AGN that match the Seyfert 2 galaxy classification criteria, but display unusually wide "narrow" lines, with the 4959 Å and 5007 Å nebular lines overlapping w…
South African night sky brightness during high aerosol epochs
Hartmut Winkler, Francois van Wyk, Fred Marang
Sky conditions in the remote, dry north-western interior of South Africa are now the subject of considerable interest in view of the imminent construction of numerous solar power p…
Line, LINER, linest - from micro-AGN to ultra-luminous LINERs. One and the same?
Hartmut Winkler
This paper compares the optical spectra of a wide range of galaxies categorised as members of the Low Ionisation Nuclear Emission Region (LINER) class of active galactic nuclei (AG…
Dust in the Radio Galaxy and Merger Remnant NGC 1316 (Fornax A)
Bernard Duah Asabere, Cathy Horellou, Hartmut Winkler +2
We present dust maps of NGC 1316 (Fornax A), a well-studied early-type galaxy located in the outskirts of the Fornax cluster. We used the Large APEX BOlometer CAmera (LABOCA), oper…
