Constructing the Milky Way Stellar Halo in the Galactic Center by Direct Orbit Integration
Chengqun Yang, Ling Zhu, Behzad Tahmasebzadeh +2
The halo stars on highly radial orbits should inevitably pass the center regions of the Milky Way. Under the assumption that the stellar halo is in dynamical equilibrium and axisym…
Orbit-Superposition Dynamical Modeling of Barred Galaxies
Behzad Tahmasebzadeh, Ling Zhu, Juntai Shen +2
Barred structures are important in understanding galaxy evolution, but they were not included explicitly in most dynamical models for nearby galaxies due to their complicated morph…

We report the discovery of ancient massive merger events in the early-type galaxies NGC 1380 and NGC 1427, members of the Fornax galaxy cluster. Both galaxies have been observed by…
The SAMI Galaxy Survey: The internal orbital structure and mass distribution of passive galaxies from triaxial orbit-superposition Schwarzschild models
Giulia Santucci, Sarah Brough, Jesse van de Sande +17
