Research of signs of star formation in three S0 galaxies – members of isolated pairs

We obtained and analyzed long-slit spectra of three lenticular galaxies with optical rings: PGC 48114, ESO 234-011, and ESO 444-076. Ionized gas was detected in all of them. In PGC 48114, the excitation mechanism of the ionized gas differs along the ring, despite the consistent kinematics of the ionized gas and stars...

Ionized Gas and Merger-triggered Star Formation in the Galaxy NGC 1222

We obtained narrowband images in the emission lines Hα, [N II]λ6583, and [O III]λ5007 at the 2.5 m telescope of the Caucasus Mountain Observatory (CMO) of the Sternberg Astronomical Institute of the Moscow State University with photometer MaNGaL, which showed that the ionized gas in the galaxy NGC 1222 resides in a res...
