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…
Milky Way Mass with K Giants and BHB Stars Using LAMOST, SDSS/SEGUE, and Gaia: 3D Spherical Jeans Equation and Tracer Mass Estimator
Sarah A. Bird, Xiang-Xiang Xue, Chao Liu +8
We measure the enclosed Milky Way mass profile to Galactocentric distances of and kpc using the smooth, diffuse stellar halo samples of Bird et al. The samples ar…
Is the core-cusp problem a matter of perspective: Jeans Anisotropic Modeling against numerical simulations
Wenting Wang, Ling Zhu, Zhaozhou Li +14
Mock member stars for 28 dwarf galaxies are constructed from the cosmological Auriga simulation, which reflect the dynamical status of realistic stellar tracers. The axis-symmetric…
The Fornax3D project: discovery of ancient massive merger events in the Fornax cluster galaxies NGC 1380 and NGC 1427
Ling Zhu, Glenn van de Ven, Ryan Leaman +16
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
Dynamical models are crucial for uncovering the internal dynamics of galaxies, however, most of the results to date assume axisymmetry, which is not representative for a significan…
Different Formation Scenarios of Counter-rotating Stellar Disks in Nearby Galaxies
Min Bao, Yanmei Chen, Pengpei Zhu +7
Using the integral field unit (IFU) data from Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we select a sample of 101 galaxies with counter-rotating stellar d…
