MNRAS Advance Access published January 27, 2014 MNRAS (2014) doi:10.1093/mnras/stt2365 Decoupled gas kinematics in isolated S0 galaxies Ivan Yu. ... Seven of 12 galaxies have revealed the presence of extended ionized-gas discs whose rotation is mostly decoupled from the stellar kinematics. ... Isolated galaxies are such galaxies. ... Similarly, we have found the shock-like excitation of the emission-line gas in the inclined gaseous disc of S0 galaxy NGC 7743 (Katkov, Moiseev & Sil'chenko 2011). ...
