Hi emission line
Web…lines, in astronomical spectroscopy, bright emission lines in the spectra of certain nebulae (H II regions), not observed in the laboratory spectra of the same gases, because on Earth the gases cannot be rarefied sufficiently. The term forbidden is misleading; a more accurate description would be “highly improbable.” The emissions… Read More WebAdditionally, the data show a strong 630.0 nm (red-line) auroral emission. Observations of pulsating aurora are typically reported at 557.7 and 427.8 nm, as these wavelengths are more sensitive to high-energy (∼ tens of keV) electron precipitation. In contrast, 630.0 nm emission is generated preferentially by low-energy soft electron ...

WebThe HI line has an extremely small natural width: for a temperature of the gas of 100 K the width of the line is ~ 1 km sec-1the observed lines are always much larger. Most of the commonly observed broadening is, therefore, due to Doppler shifts caused by the motion of the emitting regions relative to the observer. WebThe Hydrogen 21-cm Line. The hydrogen in our galaxy has been mapped by the observation of the 21-cm wavelength line of hydrogen gas. At 1420 MHz, this radiation …
WebSep 6, 2001 · We have detected the neutral atomic hydrogen (HI) emission line at a cosmologically significant distance (z=0.18) in the rich galaxy cluster Abell 2218 with the Westerbork Synthesis Radio Telescope. The HI emission originates in a spiral galaxy 2.0 megaparsecs from the cluster core.
WebEmission Line Widths The extent of Hi in spiral galaxies usually reaches much further past the regions occupied by bright stars. So, it's a great tool for revealing how big spirals actually are.
