The extended Planetary Nebula Spectrograph (ePN.S) early type galaxy survey: the kinematic diversity of stellar halos
Claudia Pulsoni, Ortwin Gerhard, Magda Arnaboldi +2
In this contribution we report on a kinematic study for 33 early type galaxies (ETGs) into their outer halos (average 6 effective radii, Re). We use planetary nebulae (PNe) as trac…
The kinematics of the outer halo of M87 as mapped by planetary nebulae
A. Longobardi, M. Arnaboldi, O. Gerhard +2
We present a kinematic study of a sample of 298 planetary nebulas (PNs) in the outer halo of the central Virgo galaxy M87 (NGC~4486). The line-of-sight velocities of these PNs are…
Three dynamically distinct stellar populations in the halo of M49
J. Hartke, M. Arnaboldi, O. Gerhard +6
M49 (NGC 4472) is the dominant galaxy in subcluster B of the Virgo Cluster, and a benchmark for studying the build-up of the extended halos of brightest group galaxies in the outsk…
