The SAMI Galaxy Survey: embedded discs and radial trends in outer
  dynamical support across the Hubble sequence
  We study the balance in dynamical support of 384 galaxies with stellar
kinematics out to >1.5R_e in the Sydney AAO Multi-object Integral Field (SAMI)
Galaxy Survey. We present radial dynamical profiles of the local rotation
dominance parameter, V/sigma, and local spin, lambda_loc. Although there is a
broad range in amplitude, most kinematic profiles monotonically increase across
the probed radial range. We do not find many galaxies with kinematic
transitions such as those expected between the inner in-situ and outer accreted
stars within the radial range probed. We compare the V/sigma gradient and
maximum values to the visual morphologies of the galaxies to better understand
the link between visual and kinematic morphologies. We find that the radial
distribution of dynamical support in galaxies is linked to their visual
morphology. Late-type systems have higher rotational support at all radii and
steeper V/sigma gradients compared to early-type galaxies. We perform a search
for embedded discs, which are rotationally supported discy structures embedded
within large scale slowly or non-rotating structures. Visual inspection of the
kinematics reveals at most three galaxies (out of 384) harbouring embedded
discs. This is more than an order of magnitude fewer than the observed fraction
in some local studies. Our tests suggest that this tension can be attributed to
differences in the sample selection, spatial sampling and beam smearing due to
seeing.
