Planetary nebula kinematics in NGC 1316: A young Sombrero

McNeil, Emily; Freeman, Kenneth; Arnaboldi, Magda; Gerhard, Ortwin

Description

Aims. 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. Methods. 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,...[Show more]
