On Beaming due to coherent inverse Compton scattering
Thomas Kunzl, Harald Lesch, Axel Jessner
We calculate the beaming of coherent emission by means of geometrical optics. When spherical elementary waves are phase-coupled in that way that constructive interference occurs al…
Relativistic electron beams in IDV blazars
A. R. Crusius-W"atzel, H. Lesch
The observed variability of BL Lac objects and Quasars on timescales <1 day (intraday variability, IDV) have revealed radio brightness temperatures up to 10^{16}-10^{20} K. These v…
Natural Polarization Modes in Pulsar Magnetospheres
Alexis von Hoensbroech, Harald Lesch, Thomas Kunzl
We present a comprehensive investigation of the radio polarization properties within the theory of natural electromagnetic wave modes in pulsar magnetospheres. Taking into account…
Magnetic fields and rotation of spiral galaxies
E. Battaner, H. Lesch, E. Florido
We present a simplified model in which we suggest that two important galactic problems -the magnetic field configuration at large scales and the flat rotation curve- may be simulta…
On the Possibility of Curvature Radiation from Radio Pulsars
H. Lesch, A. Jessner, M. Kramer +1
We consider the widespread hypothesis that coherent curvature radiation is responsible for the radio emission of pulsars. The comparison of energy conservation and the published da…
