摘要: Observations of intracluster gas bulk motions and turbulence in clusters groups galaxies should provide important information about physical conditions the intergalactic gas. Thanks to high spectral resolution radio detectors, hyperfine structure (HFS) lines highly-charged ions might help this respect. Though not yet observed, intensities emission absorption HFS from hot interstellar medium elliptical are estimated be on limit abilities existing instruments. The most interesting for purpose discussed.
