First direct dynamical detection of a dual supermassive black hole system at sub-kiloparsec separation
Karina. T. Voggel, Anil C. Seth, Holger Baumgardt +7
We investigated whether the two recently discovered nuclei in NGC7727 both host a super-massive black hole (SMBH). We used the high spatial resolution mode of the integral-field sp…
Accelerating NBODY6 with a GPU-Enabled Particle-Particle Particle-Tree Scheme
Anthony D. Arnold, Holger Baumgardt, Long Wang
We describe a modified version of the NBODY6 code for simulating star clusters which greatly improves computational efficiency while sacrificing little in the way of accuracy. The…
Testing the tidal stripping scenario of ultra-compact dwarf galaxy formation by using internal properties
Rebecca J. Mayes, Michael J. Drinkwater, Joel Pfeffer +5
We use the hydrodynamical EAGLE simulation to test if ultra-compact dwarf galaxies (UCDs) can form by tidal stripping by predicting the ages and metallicities of tidally stripped g…
Central kinematics of the Galactic globular cluster M80
Fabian Göttgens, Sebastian Kamann, Holger Baumgardt +7
We use spectra observed with the integral-field spectrograph MUSE to reveal the central kinematics of the Galactic globular cluster Messier 80 (M80, NGC 6093). Using observations o…
Towards Realistic Modeling of the Astrometric Capabilities of MCAO Systems: Detecting an Intermediate Mass Black Hole with MAVIS
Stephanie Monty, Francois Rigaut, Richard McDermid +9
Accurate astrometry is a key deliverable for the next generation of multi-conjugate adaptive optics (MCAO) systems. The MCAO Visible Imager and Spectrograph (MAVIS) is being design…
Contribution of stripped nuclei to the ultracompact dwarf galaxy population in the Virgo Cluster
Rebecca J. Mayes, Michael. J. Drinkwater, Joel Pfeffer +5
We use the hydrodynamical EAGLE simulation to predict the numbers, masses and radial distributions of tidally stripped galaxy nuclei in massive galaxy clusters, and compare these r…
