NGC 5746: formation history of a massive disc-dominated galaxy
Marie Martig, Francesca Pinna, Jesús Falcón-Barroso +6
The existence of massive galaxies lacking a classical bulge has often been proposed as a challenge to CDM. However, recent simulations propose that a fraction of massive disc ga…
Mapping Accreted Stars in Early-Type Galaxies Across the Mass-Size Plane
Thomas A. Davison, Mark A. Norris, Ryan Leaman +3
Galaxy mergers are instrumental in dictating the final mass, structure, stellar populations, and kinematics of galaxies. Cosmological galaxy simulations indicate that the most mass…
Joint Gas and Stellar Dynamical Models of WLM: An isolated dwarf galaxy within a cored, prolate DM halo
Gigi Y. C. Leung, Ryan Leaman, Giuseppina Battaglia +4
We present multi-tracer dynamical models of the low mass (), isolated dwarf irregular galaxy WLM in order to simultaneously constrain the inner slope of the dark…
What to expect when using globular clusters as tracers of the total mass distribution in Milky Way-mass galaxies
Meghan E. Hughes, Prashin Jethwa, Michael Hilker +8
Dynamical models allow us to connect the motion of a set of tracers to the underlying gravitational potential, and thus to the total (luminous and dark) matter distribution. They a…
Dynamical modelling of globular clusters: challenges for the robust determination of IMBH candidates
Francisco I. Aros, Anna C. Sippel, Alessandra Mastrobuono-Battisti +3
The presence or absence of intermediate-mass black holes (IMBHs) at the centre of Milky Way globular clusters (GCs) is still an open question. This is either due to observational r…
On the accretion of a new group of galaxies onto Virgo: I. Internal kinematics of nine in-falling dEs
Bahar Bidaran, Anna Pasquali, Thorsten Lisker +12
Galaxy environment has been shown to play an important role in transforming late-type, star-forming galaxies to quiescent spheroids. This transformation is expected to be more seve…
The SAMI -- Fornax Dwarfs Survey I: Sample, observations and the specific stellar angular momentum of dwarf elliptical galaxies
Nicholas Scott, F. Sara Eftekhari, Reynier F. Peletier +13
Dwarf ellipticals are the most common galaxy type in cluster environments, however the challenges associated with their observation mean their formation mechanisms are still poorly…
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…
Inner bars also buckle. The MUSE TIMER view of the double-barred galaxy NGC 1291
J. Mendez-Abreu, A. de Lorenzo-Caceres, D. A. Gadotti +8
Double bars are thought to be important features for secular evolution in the central regions of galaxies. However, observational evidence about their origin and evolution is still…
Time Inference with MUSE in Extragalactic Rings (TIMER): Properties of the Survey and High-Level Data Products
Dimitri A. Gadotti, Patricia Sánchez-Blázquez, Jesús Falcón-Barroso +14
The Time Inference with MUSE in Extragalactic Rings (TIMER) project is a survey with the VLT-MUSE integral-field spectrograph of 24 nearby barred galaxies with prominent central st…
