Abstract:
We present positions and velocities for 796 planetary nebulae (PNe) in
the Fornax Brightest Cluster Galaxy NGC 1316 (Fornax A). The planetary
nebulae and existing kinematics are used to explore the rotation of
this merger remnant and constrain dynamical models.
Using FORS2 on the VLT, the PN velocities were measured using a
counter-dispersed slitless-spectroscopy technique that produced the
largest-to-date sample outside of the Local Group. Spherical,
non-rotating, constant-anisotropy Jeans models were con- strained by
observations of the planetary nebulae and existing integrated light
spectra.
Description:
The planetary nebula kinematics were measured using counter-dispersed
spectroscopy with FORS2 on the VLT. NGC 1316 was observed with 7
fields on 3-5 November 2002.
