Query: The line of sight velocity distributions of simulated merger remnants   We use Gauss-Hermite functions to study the line of sight velocity
distributions in simulated merger remnants. Our sample contains sixteen
remnants; eight produced by mergers between disk galaxies of equal mass and
eight produced by mergers between disk galaxies with mass ratios of 3:1. The
equal-mass mergers display a wide range of kinematic features, including
counterrotation at large radii, orthogonally rotating cores, and misaligned
rotational axes. Most of the unequal-mass remnants exhibit fairly regular
disk-like kinematics, although two have kinematics more typical of the
equal-mass remnants. Our results may be compared to observations of early type
objects, including ellipticals with misaligned kinematic axes, counterrotating
systems, and S0 galaxies.
