Mapping the dark matter halo of early-type galaxy NGC 2974 through orbit-based models with combined stellar and cold gas kinematics
Meng Yang, Ling Zhu, Anne-Marie Weijmans +4
We present an orbit-based method of combining stellar and cold gas kinematics to constrain the dark matter profile of early-type galaxies. We apply this method to early-type galaxy…
A dwarf-dwarf merger and dark matter core as a solution to the Globular Cluster problems in the Fornax dSph
Gigi Y. C. Leung, Ryan Leaman, Glenn van de Ven +1
The five globular clusters (GCs) of the Fornax dSph are puzzling for two reasons; the mass in GCs is high with respect to the galaxy's old stellar mass, and their survival and larg…
Is There a Fundamental Upper Limit to the Mass of a Star Cluster?
Mark A. Norris, Glenn van de Ven, Sheila J. Kannappan +2
The discovery around the turn of the millenium of a population of very massive (M > 210 M) compact stellar systems (CSS) with physical properties (radiu…
A study of stellar orbit fractions: simulated IllustrisTNG galaxies compared to CALIFA observations
Dandan Xu, Ling Zhu, Robert Grand +16
Motivated by the recently discovered kinematic "Hubble sequence" shown by the stellar orbit-circularity distribution of 260 CALIFA galaxies, we make use of a comparable galaxy samp…
Evaluating the ability of triaxial Schwarzschild modelling to estimate properties of galaxies from the Illustris simulation
Yunpeng Jin, Ling Zhu, R. J. Long +4
We evaluate the capabilities of Schwarzschild's orbit-superposition method by applying it to galaxies from the large scale, high resolution Illustris simulation. Nine early-type ga…
Combining Stellar Populations with Orbit-Superposition Dynamical Modelling - the Formation History of the Lenticular Galaxy NGC 3115
Adriano Poci, Richard M. McDermid, Ling Zhu +1
We present a combination of the Schwarzschild orbit-superposition dynamical modelling technique with the spatially-resolved mean stellar age and metallicity maps to uncover the for…
