Decoupled gas kinematics in isolated S0 galaxies
Ivan Katkov, Olga Sil'chenko, Victor Afanasiev
A sample of completely isolated S0 galaxies has been studied by means of long-slit spectroscopy at the Russian 6-m telescope. 7 of 12 galaxies have revealed a presence of extended…
Decoupled gas kinematics in isolated early-type disc galaxies
Ivan Katkov, Olga Sil'chenko, Victor Afanasiev
We have studied a sample of completely isolated galaxies by means of long-slit spectroscopy at the 6-m telescope. We have found that 7 of 12 (58 +/- 14 %) galaxies have revealed a…
Lenticular galaxy IC 719: current building of the counterrotating large-scale stellar disk
Ivan Yu. Katkov, Olga K. Sil'chenko, Victor L. Afanasiev
We have obtained and analyzed long-slit spectral data for the lenticular galaxy IC 719. In this gas-rich S0 galaxy, its large-scale gaseous disk counterrotates the global stellar d…
