Journal ArticleDOI
The Galaxy in Context: Structural, Kinematic and Integrated Properties
TL;DR: In this paper, the authors review the key integrated, structural and kinematic parameters of the Milky Way and point to uncertainties as well as directions for future progress, and point out the importance of near field observations.
Journal ArticleDOI
Intracluster Planetary Nebulae in the Hydra I cluster
TL;DR: Using the multislit imaging spectroscopy (MSIS) technique at the FORS2 spectrograph on VLT-UT1, this article identified 60 Intracluster Planetary Nebula (ICPN) candidates associated with the Intrluster Light (ICL) in the central region of the Hydra I cluster.
Journal ArticleDOI
A KMOS survey of the nuclear disk of the Milky Way - I. Survey design and metallicities
T. K. Fritz,T. K. Fritz,Lee Patrick,Lee Patrick,Lee Patrick,Anja Feldmeier-Krause,Anja Feldmeier-Krause,Rainer Schödel,Mathias Schultheis,Ortwin Gerhard,G. Nandakumar,Nadine Neumayer,Francisco Nogueras-Lara,Mercedes Prieto,Mercedes Prieto +14 more
TL;DR: In this paper, the authors presented a survey of the stars in the nuclear disk reaching the old populations of the Milky Way and derived metallicities using the CO 2-0 and Na I K -band spectral features.
Journal ArticleDOI
A tale of two tails and an off-centered envelope: diffuse light around the cD galaxy NGC 3311 in the Hydra I cluster
TL;DR: In this paper, Ks and V-band surface photometry as well as deep long-slit spectra were analyzed to establish a link between the structures in the light distribution, the absorption line kinematics, and the LOS velocity distributions of nearby galaxies and planetary nebulae (PNs).
Journal ArticleDOI
The Formation of a Disk Galaxy within a Growing Dark Halo
Markus Samland,Ortwin Gerhard +1 more
TL;DR: In this article, a 3D chemo-dynamical model for the formation and evolution of a massive disk galaxy, within a growing dark halo whose mass evolves according to cosmological simulations of structure formation, is presented.
