Size and Orientation of the `Z' in ZRGs
Christian Zier
Some X-shaped radio galaxies (XRGs) show a Z-symmetric morphology in the less luminous secondary lobes. Our geometrical arguments strongly support a merger of two galaxies as mecha…
Orientation and size of the `Z' in `X'-shaped radio galaxies
Christian Zier
Some X-shaped radio galaxies show a Z-symmetric morphology in the less luminous secondary lobes. Within the scenario of a merger between two galaxies, each hosting a supermassive b…
Single and binary Black Holes and their active environment
Peter L. Biermann, Mihaela Chirvasa, Heino Falcke +2
In this short review we describe some of the latest endeavours to understand the activity around Black Holes. First, it has been possible to demonstrate that a large part of the el…
Binary black holes and tori in AGN II. Can stellar winds constitute a dusty torus?
Christian Zier, Peter L. Biermann
We determine the properties of the stellar torus that we showed in a previous paper to result as a product of two merging black holes. If the surrounding stellar cluster is as mass…
