Galactic Spiral Structure in H I Emission and Self-Absorption S. J. Gibson (NAIC) H I Self-Absorption (HISA) occurs when cold H I lies in front of warmer H I emission (HIE) at the same radial velocity. The map and spectra AT LEF T show HISA in the Perseus spiral arm in the Canadian Galactic Plane Survey (CGPS; Taylor et al. ... The basic components of the model are shown AT LEF T with all 3 types of CNM cells (shock-induced, local, ambient disk), but without lumpy dispersion in the velocity field. ...

... We study the variation of the line width and electron density as a function of height above the north polar coronal hole from forbidden spectral lines of Si VIII. The spectra were obtained with the Solar Ultraviolet Measurement of Emitted Radiation spectrometer flown on the Solar and Heliospheric Observatory spacecraft.The present data show that the non-thermal velocity increases from at 27 arcsec above the limb to some 250 arcsec ( 180,000 km) above the limb. ...

Search of spectral-spatial fluctuations . ... After recombination of hydrogen the one of probable mechanism of formation CMBR fluctuations there can be a scattering by small density inhomogeneities if they have peculiar velocities and opacity for electromagnetic emission. Peculiar velocities of various spatial scale are predicted in all models of evolution. ... For increase the time of accumulation of a signal with our antenna the drift curves near celestial poles were used at declination +89.5 . ...

... Many extragalactic objects for which radial velocities are desired display strong emission lines. ... EMSAO, a companion to the cross-correlation task XCSAO (Kurtz et al. 1992), was written to find emission lines automatically, compute redshifts for each identified line, and combine them into a single radial velocity. ... Figure: This EMSAO Summary page shows line centers and fit information for a night sky spectrum. ... To test EMSAO adequately, a lot of emission line spectra were needed. ...

The large magnetic cloud caused by coronal mass ejection at the Sun on January 6, 1997 came to the Earth at early morning on January 10 and continue to interact with Earth's magnetosphere till January 11 (see for example home page of this event prepeared by Dr. M.Peredo http://www-istp.gsfc.nasa.gov/istp/cloud_jan97/event.html ). ...

... 2001: . The distances to 50 galaxies in the vicinity of three most nearby galaxy clusters were measured. The radius of the "zero velocity sphere", isolating each group from the cosmological expansion is in the range from 0.95 to 1.25 Mpc for these groups, leads to the estimates of the total mass of groups ranging from 1.2 to 2.7 trillion solar masses. These results agree with the value of the mean matter density in the Local Universe from 0.05 to 0.10 in critical density units. ...
