A 3.5-million Solar Masses Black Hole in the Centre of the Ultracompact Dwarf Galaxy Fornax UCD3
Anton V. Afanasiev, Igor V. Chilingarian, Steffen Mieske +16
The origin of ultracompact dwarfs (UCDs), a class of compact stellar systems discovered two decades ago, still remains a matter of debate. Recent discoveries of central supermassiv…
Detection of Supermassive Black Holes in Two Virgo Ultracompact Dwarf Galaxies
Christopher P. Ahn, Anil C. Seth, Mark den Brok +13
We present the detection of supermassive black holes (BHs) in two Virgo ultracompact dwarf galaxies (UCDs), VUCD3 and M59cO. We use adaptive optics assisted data from the Gemini/NI…
Probing the boundary between star clusters and dwarf galaxies: A MUSE view on the dynamics of Crater/Laevens I
Karina Voggel, Michael Hilker, Holger Baumgardt +5
We present MUSE observations of the debated ultra faint stellar system Crater. We spectroscopically confirm 26 member stars of this system via radial velocity measurements. We deri…
Dynamical Evolution of Outer-Halo Globular Clusters
Andreas H. W. Küpper, Akram H. Zonoozi, Hosein Haghi +5
Outer-halo globular clusters show large half-light radii and flat stellar mass functions, depleted in low-mass stars. Using N-body simulations of globular clusters on eccentric orb…
The AIMSS Project III: The Stellar Populations of Compact Stellar Systems
Joachim Janz, Mark A. Norris, Duncan A. Forbes +11
In recent years, a growing zoo of compact stellar systems (CSSs) have been found whose physical properties (mass, size, velocity dispersion) place them between classical globular c…
Major mergers with small galaxies - the discovery of a Magellanic-type galaxy at z=0.12
Andreas Koch, Matthias J. Frank, Anna Pasquali +2
We report on the serendipitous discovery of a star-forming galaxy at redshift z=0.116 with morphological features that indicate an ongoing merger. This object exhibits two clearly…
