摘要

We present a study of the kinematics of the outer regions of the early-type galaxy NGC 1316, based on radial velocity measurements of 43 planetary nebulae as well as deep integrated light absorption line spectra. The smoothed velocity held of NGC 1316 indicates fast rotation at a distance of 16 kpc, possibly associated with an elongated f...更多
