Planetary nebulae populations in the haloes of nearby massive early-type galaxies
J. Hartke, M. Arnaboldi, O. Gerhard +8
Planetary nebulae (PNe) are excellent tracers of the metal-poor haloes of nearby early-type galaxies. They are commonly used to trace spatial distribution and kinematics of the hal…
The Halos and Environments of Nearby Galaxies (HERON) Survey IV: Complexity in the boxy galaxies NGC 720 and NGC 2768
Andreas J. Koch-Hansen, Anna Pasquali, R. Michael Rich +2
The shapes of galaxies, in particular their outer regions, are important guideposts to their formation and evolution. Here we report on the discovery of strongly box-shaped morphol…
The epoch of the Milky Way's bar formation: dynamical modelling of Mira variables in the nuclear stellar disc
Jason L. Sanders, Daisuke Kawata, Noriyuki Matsunaga +4
A key event in the history of the Milky Way is the formation of the bar. This event affects the subsequent structural and dynamical evolution of the entire Galaxy. When the bar for…
On the /Fe bimodality of the M31 disks
Chiaki Kobayashi, Souradeep Bhattacharya, Magda Arnaboldi +1
An outstanding question is whether the /Fe bimodality exists in disk galaxies other than in the Milky Way. Here we present a bimodality using our state-of-the-art galactic chemi…
The extended Planetary Nebula Spectrograph (ePN.S) early-type galaxy survey: The specific angular momentum of ETGs
C. Pulsoni, O. Gerhard, S. M. Fall +5
Mass and angular momentum are key parameters of galaxies. Their co-evolution establishes an empirical relation between the specific stellar angular momentum j* and the stellar mass…
