Neutral hydrogen distribution in the region of radio source Cygnus X . ... HI distribution in the region of radio source Cygnus X and supernova remnant G78.2+2.1 has been investigated from observations in 21 cm radio line using radio telescope RATAN-600. ... The existance of the large HI shell and a cavity in molecular gas distribution around Cygnus X indicates this radio source most probably to represent a united structure and whole gas may be drived by stellar wind of Cyg OB2 stellar assotiation. ...

... 2005: . Using the radio telescope GMRT (India) and the 6 m telescope of SAO RAS, maps of the distribution of neutral and ionized hydrogen have been obtained in 60 nearby dwarf galaxies whose luminosities range from 1/100 to 1/10000 of that of the Milky Way. ... DDO 68 - the nearest galaxy with extremely low metallicity. ... By many parameters DDO 68 is close to the famous galaxy IZw 18, one of several candidates for young galaxies in the nearby Universe, however, it is located 2.5 times closer. ...
