Population X: Are the super-Eddington X-ray sources beamed jets in microblazars or intermediate mass black holes?
Elmar Koerding, Heino Falcke, Sera Markoff
Recent X-ray observations reveal an increasing number of X-ray sources in nearby galaxies exceeding luminosities of L_x > 2 10^39 erg/s. Assuming isotropic emission, the Eddington…

The Power of Jets: New Clues from Radio Circular Polarization and X-rays
Heino Falcke, Thomas Beckert, Sera Markoff +3
Jets are ubiquitous in accreting black holes. Often ignored, they may be a major contributor to the emitted spectral energy distribution for sub-Eddington black holes. For example,…

Stability Analysis of the Hubbard-Model
I. Grote, E. Koerding, F. Wegner
An effective Hartree-Fock-Bogoliubov-type interaction is calculated for the Hubbard-model in second order in the coupling by means of flow-equations. A stability analysis is perfor…
