Abstract -- The strengths of magnetic fields in interstellar gas clouds are obtained through observations of the circular polarization of spectral line radiation. ... To infer information about these irregularities from the observational data, we develop statistical relationships between the rms values of the irregular component of the magnetic field and spatial variations in the circular polarization of the spectral line radiation. ...

A press release on the Canadian Galactic Plane Survey was associated with this poster. ... Below are maps of HI emission, HISA, and 12 CO emission in the eastern 25% of the survey, given as projections along the velocity ( Figure 1 ) and latitude ( Figure 2 ) axes. ... 2000, A. J. , submitted . ... GIF | ... We are developing automated methods of locating HISA in velocity cubes by removing large-scale emission in space and velocity and flagging small-scale dark residuals. ...

... Because of the low conductivity, the magnetic coupling is weak and depends critically on density, temperature, ionisation rate and charged species. ... Implications When the Hall regime dominates near the midplane and ambipolar diffusion is dominant closer to the surface, a thicker layer of the disc is unstable to MRI perturbations and modes grow faster than under the ambipolar diffusion approximation. ... Right panel: For weak coupling, Hall limit perturbations grow until vA/cs ~ 2.9. ...

... The analysis shows, that asteroid ­ rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust ­ gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid ­ rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...

... Several attempts to discover the FICN signal in VLBI nutation series made during last years failed. ... We investigated several VLBI CPO series by means of spectral and wavelet analysis. It has been shown that there are several periodic signals with close amplitude around the expected FICN period without any prevailing one that can be reliably associated with the FICN. ... DATA ANALYSIS We analyzed several CPO series obtained in IVS analysis centers by means of spectral and wavelet analysis. ...
