The giant low surface brightness galaxy Malin 1: new constraints for its molecular gas mass from GBT/ARGUS observations
Gaspar Galaz, David T. Frayer, Matias Blaña +8
We report on results from GBT/ARGUS CO(1-0) observations for the giant low surface brightness galaxy Malin 1, which allow us to determine an upper limit for its CO mass, and…
Dwarfs in the Milky Way halo outer rim: first in-fall or backsplash satellites?
Matias Blaña, Andreas Burkert, Michael Fellhauer +2
Leo T is a gas-rich dwarf located at 414kpc distance from the Milky Way (MW) and it is currently assumed to be on its first approach. Here, we present an analysi…
Unravelling stellar populations in the Andromeda Galaxy
Grzegorz Gajda, Ortwin Gerhard, Matías Blaña +4
To understand the history and formation mechanisms of galaxies it is crucial to determine their current multidimensional structure. Here we focus on stellar population properties,…
The survey of Planetary Nebulae in Andromeda (M31) II. Age-velocity dispersion relation in the disc from Planetary Nebulae
Souradeep Bhattacharya, Magda Arnaboldi, Nelson Caldwell +7
The age-velocity dispersion relation is an important tool to understand the evolution of the disc of the Andromeda galaxy (M31) in comparison with the Milky Way. We use Planetary N…
The stellar populations of the central region of M31
R. P. Saglia, M. Opitsch, M. H. Fabricius +3
We continue the analysis of the dataset of our spectroscopic observation campaign of M31, by deriving simple stellar population properties (age metallicity and alpha-elements overa…
How fast is mass-segregation happening in hierarchical formed embedded star clusters?
R. Dominguez, M. Fellhauer, M. Blana +2
We investigate the evolution of mass segregation in initially sub-structured young embedded star clusters with two different background potentials mimicking the gas. Our clusters a…
