Next: Absorption bands identified with Up: Optical spectrum of IRAS04296 Previous: Emission molecular bands . We measured the radial velocity using our best spectrum, that obtained in February, 1997. ... It should be noted also that the value of radial velocity we derived agrees with the value of which was given by Omont et al. (1993) from CO data and by Decin et al. (1998) from optical spectrum. ...

... Absorption by neutral atomic hydrogen in luminous spiral galaxies provides an excellent tool to study the gas kinematics in their nuclear regions. ... Since the absorption lines are intrinsically narrow as a result of the low temperatures of the optically thick gas, typically 30 to 150 K (Dickey, Salpeter & Terzian 1979), it is surprising that numerous galaxies show H I absorption over a broad range of velocities (a few hundred kms -1 ); see e.g., Fig. ... range . ...

... High Velocity Clouds and the Milky Way . ... High velocity clouds (HVCs) of gas have been seen for decades but their origins and destinations have remained mysterious. Recent measurements have now placed at least one of these clouds in the halo of our Milky Way Galaxy , while other measurements have determined the relative abundance of cloud elements. ...
