Spin-Polarized Standing Waves in the Fermi Surface of a Ferromagnetic Thin Film
J. Schaefer, M. Hoinkis, Eli Rotenberg +2
The spin-selective electron reflection at a ferromagnetic-paramagnetic interface is investigated using Fe films on a W(110) substrate. Angle-resolved photoemission of the majority…
Isospin breaking in pion-nucleon scattering at threshold by radiative processes
T. E. O. Ericson, A. N. Ivanov
We investigate the dispersive contribution by radiative processes such as (pi- proton to neutron gamma) and (pi- proton to Delta gamma) to the pion-nucleon scattering lengths of ch…
Ovi Column Density Distribution in the Local Bubble - Results from 3D Adaptive Mesh Refinement Simulations
Miguel A. de Avillez, Dieter Breitschwerdt
The Local Bubble (LB) is an X-ray emitting region extending 100 pc in radius in the Galactic plane and 300 pc perpendicular to it, and it is embedded in a somewhat larger H{\sc i}…
Keynote Lecture: Galactic and Extragalactic Bubbles
D. Breitschwerdt, M. A. de Avillez, M. J. Freyberg
The observational and theoretical state of Galactic and extragalactic bubbles are reviewed. Observations of superbubbles are discussed, with some emphasis on nearby bubbles such as…
Integrating transport equations by combining transfer matrices, transmission-reflection matrices, and Green's matrices, in the context of light propagation in foliage
Antoine Royer, Sophie Royer
In many problems, it is necessary to integrate a transport equation. Here we consider specifically light incident on a horizontally homogeneous foliage ('the canopy'), modeled as a…
Metal Enrichment and Energetics of Galactic Winds in Galaxy Clusters
W. Kapferer, D. Breitschwerdt, W. Domainko +4
We investigate efficiency and time dependence of metal enrichment processes in the Intra-Cluster Medium (ICM). In this presentation we concentrate on the effects of galactic winds.…
