We present new high resolution (100) neutral hydrogen (H i) self-absorption images of the Riegel-Crutcher cloud obtained with the Australia Telescope Compact Array and the Parkes Radio Telescope. The Riegel-Crutcher cloud lies in the direction of the Galactic center at a distance of 125±25 pc. Our observations resolve the very large, nearby sheet of cold hydrogen into a spectacular network of d...

The demagnetization processes and the magnetic viscosity have been studied on a bulk-amorphous Nd 60 Fe 30 Al 10 rod at room temperature. Many unique magnetic properties have been found in this novel hard magnetic material. A clear hysteresis was present on the minor loops, though the total and irreversible susceptibilities exhibited single-phase magnet behavior. A signi"cant magnetic viscosity...

We present an analysis of the rotation measures (RMs) of polarized extragalactic point sources in the Southern Galactic Plane Survey. This work demonstrates that the statistics of fluctuations in RM differ for the spiral arms and the interarm regions. Structure functions of RM are flat in the spiral arms, while they increase in the interarms. This indicates that there are no correlated RM fluct...

We present a statistical analysis of the interstellar medium (ISM) polarization from the largest compilation available of starlight data, which comprises ∼ 5500 stars. The measured correlation between the mean polarization degree and extinction indicates that ISM dust grains are not fully aligned with the uniform component of the large-scale Galactic magnetic field. Moreover, we estimate the ra...

Radiative transfer equilibrium models of nearby interstellar matter (ISM) are required to determine the boundary conditions of the heliosphere from astronomical observations of nearby stars. These models are also constrained by data on the ISM inside of the solar system, including pickup ion, anomalous cosmic rays, and in situ He data. The two best ISM models give semi-empirical filtration fact...

We follow the ambipolar-diffusion–driven formation and evolution of a fragment in a magnetically supported molecular cloud, until a hydrostatic protostellar core forms at its center. This problem was formulated in Paper I. We determine the density, velocity and magnetic field as functions of space and time, and the contribution of ambipolar diffusion and Ohmic dissipation to the resolution of t...

The Ginzburg{Landau (GL) equations of superconductivity provide a computational model for the study of magnetic ux vortices in type-II superconduc-tors. In this article we show through numerical examples and rigorous mathematical analysis that the GL model reduces to the frozen-eld model when the charge of the Cooper pairs (the superconducting charge carriers) goes to zero while the applied eld...

The magnetosphere of the Earth and the other planets contain a variety of low frequency (f < fp, fp being the proton gyrofrequency) waves. Several sources are known to contribute to these uctuations: (1) Waves present in the solar wind (mainly those occurring in the foreshock) are convected in the magnetosheath and possibly ampli ed passing through the shock front. (2) The bow shock modi es the...

We study a simple, kinematical model of a galactic fountain ow and show that a horizontal eld in the galactic plane can be pumped into the halo to a height of several kiloparsecs. This pumping eeect results from the topological structure of the ow in which the updraughts (represented by hot gas) form a connected network, whereas the downdraughts (associated with isolated cool clouds) are discon...

Magnetoinductive e ects in ferromagnetic conductors can be used for various sensors. Although the principle has been known for a long time, the usefulness of these e ects for practical applications was recognized recently, and intensive investigations began. Magnetoinductive e ects are related to magnetization of a magnetic conductor (wire, strip, thin lm, etc.) by a magnetic eld, which is prod...
