The Merger-Driven Origin of the Vast Extended Stellar Disc Around the Andromeda Galaxy
C. Tsakonas, M. Arnaboldi, F. Hammer +4
The closest giant spiral, the Andromeda galaxy (M31), shows compelling evidence for a recent, gas-rich major merger event. Pronounced substructures in its inner halo and a kinemati…
The survey of planetary nebulae in Andromeda (M31) VII. Predictions of a major merger simulation model compared with chemodynamical data of the disc and inner halo substructures
C. Tsakonas, M. Arnaboldi, S. Bhattacharya +5
The nearest giant spiral, M31, exhibits a kinematically hot stellar disc, a global star formation episode ~2-4 Gyr ago, and conspicuous substructures in its stellar halo that are s…
The GECKOS Survey: Identifying kinematic sub-structures in edge-on galaxies
A. Fraser-McKelvie, J. van de Sande, D. A. Gadotti +30
The vertical evolution of galactic discs is governed by the sub-structures within them. We examine the diversity of kinematic sub-structure present in the first 12 galaxies observe…
Unravelling the origins of S0 galaxies using maximum likelihood analysis of planetary nebulae kinematics
A. Cortesi, M. R. Merrifield, M. Arnaboldi +12
To investigate the origins of S0 galaxies, we present a new method of analyzing their stellar kinematics from discrete tracers such as planetary nebulae. This method involves binni…
