The Size of IDV Jet Cores
T. Beckert, T. P. Krichbaum, G. Cimo' +4
Radio variability on timescales from a few hours to several days in extragalactic flat-spectrum radio sources is generally classified as intra-day variability (IDV). The origin of…
Circular Polarization of Radio Emission from Relativistic Jets
Thomas Beckert, Heino Falcke
In inhomogeneous optically thick synchrotron sources a substantial part of the electron population at low energies can be hidden by self-absorption and overpowered by high energy e…
Turbulent viscosity in clumpy accretion disks. Application to the Galaxy
B. Vollmer, T. Beckert
The equilibrium state of a turbulent clumpy gas disk is analytically investigated. The disk consists of distinct self-gravitating clouds. Gravitational cloud-cloud interactions tra…
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,…
A very rapid Extreme Scattering Event in the IDV source 0954+658
G. Cimò, T. Beckert, T. P. Krichbaum +4
Extreme Scattering Events (ESEs) are dramatic variations of the flux density at Gigahertz frequencies caused by ray path distortions within an isolated inhomogeneity ("plasma lens"…
