Yougang Wang,Yougang Wang,Xiaohu Yang,Xiaohu Yang,Houjun Mo,Cheng Li,Frank C. van den Bosch,Zuhui Fan,Xuelei Chen +8 more
TL;DR: Yang et al. as mentioned in this paper studied the three-dimensional and projected shapes of galaxy groups in the Sloan Digital Sky Survey Data Release 4, and examined the alignment between the orientation of the central galaxy and the spatial distribution of satellite galaxies.
A new model for the Milky Way bar
TL;DR: In this paper, the authors used Schwarzschild's orbit-superposition technique to construct self-consistent models of the Galactic bar and found that the best fitting Gaussian bar model has a pattern speed Ωp = 60 km/s−1/kpc−1, disc mass Md = 1.0 × 1011/m⊙ and bar angle θbar = 20°.
Made-to-measure galaxy models - III. Modelling with Milky Way observations
TL;DR: In this paper, the Syer and Tremaine made-to-measure method of stellar dynamical modeling can be adapted to model a rotating galactic bar, and the results for a combined determination of the bar angle and bar pattern speed (approximate to 30 degrees and approximate to 40 km s(-1) kpc(-1)) are consistent with those determined by the N-body model.
