... 2006: . The distributions of radial ages and chemical compositions of the stellar population for several elliptical galaxies were measured from the BTA observations down to the record (to date) distances from the nucleus. ... Photometric distances were measured and peculiar radial velocities were determined for 3000 spiral galaxies from the 2MFGC catalog, compiled at the SAO RAS based on the 2MASS infrared sky survey. ...

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. ...

... Suspected G36.6-0.7 has the spectral index -0.8, it seems to be a background extragalactic source because the spectral index is too steep for SNR. ... During the last years the RATAN-600 has been used to carry out a new survey of the Galactic plane at 960 and 3900 MHz from l=342^o to l=19^o, |b| < 5.5^o, to search for new SNRs and to study the SNRs that have just been detected. Column (1) lists Galactic notation names of the new and well--known SNRs from Green's catalog; . ...
