The Gaia-ESO Survey: Probes of the inner disk abundance gradient
H. R. Jacobson, E. D. Friel, L. Jilkova +41
The nature of the metallicity gradient inside the solar circle (R_GC < 8 kpc) is poorly understood, but studies of Cepheids and a small sample of open clusters suggest that it stee…
The origin and orbit of the old, metal-rich, open cluster NGC 6791: Insights from kinematics
L. Jilkova, G. Carraro, B. Jungwiert +1
NGC 6791 is a unique stellar system among Galactic open clusters being at the same time one of the oldest open clusters and the most metal rich. Combination of its properties is pu…
A Fossil Bulge Globular Cluster revealed by VLT Multi-Conjugate Adaptive Optics
Sergio Ortolani, Beatriz Barbuy, Yazan Momany +5
The globular cluster HP1 is projected on the bulge, very close to the Galactic center. The Multi-Conjugate Adaptive Optics (MCAO) Demonstrator (MAD) at the Very Large Telescope (VL…
Comparing Various Approaches to Simulating the Formation of Shell Galaxies
Ivana Ebrova, Katerina Bartoskova, Bruno Jungwiert +2
The model of a radial minor merger proposed by Quinn (1984), which successfully reproduces the observed regular shell systems in shell galaxies, is ideal for a test-particle simula…
Quadruple-peaked Line-of-sight Velocity Distributions in Shell Galaxies
Ivana Ebrova, Lucie Jilkova, Bruno Jungwiert +4
We present an improved study of the expected shape of the line-of-sight velocity distribution in shell galaxies. We found a simple analytical expression connecting prominent and in…
Open clusters towards the Galactic center: chemistry and dynamics. A VLT spectroscopic study of NGC6192, NGC6404, NGC6583
Laura Magrini, Sofia Randich, Manuela Zoccali +5
In the framework of the study of the Galactic metallicity gradient and its time evolution, we present new high-resolution spectroscopic observations obtained with FLAMES and the fi…
Shell Galaxies, Dynamical Friction, and Dwarf Disruption
Ivana Ebrova, Bruno Jungwiert, Gabriela Canalizo +2
Using N-body simulations of shell galaxies created in nearly radial minor mergers, we investigate the error of collision dating, resulting from the neglect of dynamical friction an…
Shell Galaxies: Dynamical Friction, Gradual Satellite Decay and Merger Dating
Ivana Ebrova, Bruno Jungwiert, Gabriela Canalizo +2
With the goal to refine modelling of shell galaxies and the use of shells to probe the merger history, we develop a new method for implementing dynamical friction in test-particle…
