Descripción
We present gaseous and stellar kinematics for 14 gas-rich early-type
galaxies. Half of the galaxies show irregular gaseous velocity profiles,
with gas/star counter-rotation in 5 galaxies. We also find 5
counter-rotating stellar cores, and 5 more galaxies display stellar
nuclei kinematically decoupled from the main stellar body. Our results
indicate that the ionized gas is of external origin, and may have been
acquired recently; the merging or accretion events that brought the gas
into the galaxy have likely affected its stellar kinematics.
