SchwarMAX: a GPU-friendly Schwarzschild orbit-superposition modelling framework
HanYuan Zhang, David Chemaly, Eugene Vasiliev +3
The Schwarzschild orbit-superposition method is a highly flexible dynamical modelling tool. It constrains the mass distribution of a galaxy using line-of-sight velocity and photome…
Effects of Inner Halo Angular Momentum on the Peanut/X-shapes of Bars
Sandeep Kumar Kataria, Juntai Shen
Cosmological simulations show that dark matter halos surrounding baryonic disks have a wide range of angular momenta, measured by the spin parameter (). In this study, we bring…
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…
The North/South Asymmetry of the Galaxy: Possible Connection to the Vertical Phase Space Snail
Rui Guo, Juntai Shen, Zhao-yu Li +2
The Galaxy is found to be in disequilibrium based on recent findings of the North/South (N/S) asymmetry and the phase mixing signatures, such as a phase spiral (snail) structure in…
Large-scale Hydrodynamical Shocks as the Smoking Gun Evidence for a Bar in M31
Zi-Xuan Feng, Zhi Li, Juntai Shen +3
The formation and evolutionary history of M31 are closely related to its dynamical structures, which remain unclear due to its high inclination. Gas kinematics could provide crucia…
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…
