Quasars physical properties study based on the medium-band photometric survey
Sergey Kotov, Sergey Dodonov, Aleksandra Grokhovskaya
The study is about the quasars cosmological evolution. We used the medium-band photometric survey at the 1-m Schmidt telescope of the Byurakan Astrophysical Observatory. The HS47-2…
Study of young stellar groupings in HII regions based on the spectral and photometric data
A. S. Gusev, F. Kh. Sakhibov, A. E. Piskunov +10
We studied 102 star forming regions in seven spiral galaxies (NGC 628, NGC 783, NGC 2336, NGC 6217, NGC 6946, NGC 7331, and NGC 7678) on the basis of complex spectroscopic, photome…
Oxygen and nitrogen abundances of HII regions in six spiral galaxies
Alexander S. Gusev, Leonid S. Pilyugin, Firouz Sakhibov +3
Spectroscopic observations of 63 HII regions in six spiral galaxies (NGC 628, NGC 783, NGC 2336, NGC 6217, NGC 7331, and NGC 7678) were carried out with the 6-meter telescope (BTA)…
