Abstract / Description:Non-axisymmetric features such as bars drive
the dynamical and secular evolution of disk
galaxies by exerting gravitational torques which
redistribute mass and angular momentum. While
most ( gt; 70 %) spirals are barred in the
local Universe, early studies of the Hubble Deep
Field (HDF) suggest a remarkably low bar
fraction ( lt; 20 %) at intermediate redshifts
(z=0.5-0.8). If confirmed, this result would
imply that disks at these epochs are
fundamentally different from present-day spirals.
We revisit the recoverability, fraction, and
properties of bars at intermediate redshifts
using the two largest HST surveys to date: Galaxy
Evolution from Morphology and SEDS (GEMS) and the
Great Observatories Origins Deep Survey (GOODS).
We also present first results to analyze the
stability of bars embedded in massive halos of
various central concentrations and asymmetries.
