Formation of the Two-Armed Phase Spiral from Multiple External Perturbations
Junxian Lin, Zhao-Yu Li, Rui Guo +3
Recent studies using the Gaia DR3 data have revealed a two-armed phase spiral in the phase space in the inner disk. In this study, we present new features of the two-armed…
Recovering the pattern speeds of edge-on barred galaxies via an orbit-superposition method
Yunpeng Jin, Ling Zhu, Behzad Tahmasebzadeh +4
We developed an orbit-superposition method for edge-on barred galaxies and evaluated its capability to recover the bar pattern speed . We selected three simulated galaxies…
Deciphering the Kinematic Substructure of Local Dark Matter with LAMOST K Giants
Hai Zhu, Rui Guo, Juntai Shen +5
Numerical simulations indicate that correlations exist between the velocity distributions of stars and dark matter (DM). We study the local DM velocity distribution based on these…
North-South asymmetries in the Galactic thin disk associated with the vertical phase spiral as seen using LAMOST-Gaia stars
Jun Lin, Rui Guo, Sarah A. Bird +5
We select 1,052,469 (754,635) thin disk stars from {\it Gaia} eDR3 and LAMOST DR7 in the range of Galactocentric radius (guiding center radius ) from 8 to 11\,kpc…
Measuring the Milky Way Vertical Potential with the Phase Snail in a Model Independent Way
Rui Guo, Zhao-Yu Li, Juntai Shen +2
The vertical phase-space spiral (snail) is a direct sign of dis-equilibrium of Milky Way's disc. Nevertheless, the wrapping of the phase snail contains information of the vertical…
Schwarzschild Modeling of Barred S0 Galaxy NGC 4371
Behzad Tahmasebzadeh, Ling Zhu, Juntai Shen +15
We apply the barred Schwarzschild method developed by Tahmasebzadeh et al. (2022) to a barred S0 galaxy, NGC 4371, observed by IFU instruments from the TIMER and ATLAS3D projects.…
