RAVE stars tidally stripped/ejected from Centauri globular cluster
J. G. Fernández-Trincado, A. C. Robin, K. Vieira +7
Using six-dimesional phase-space information from the Fourth Data release of the Radial Velocity Experiment (RAVE) over the range of Galactic longitude 240 360$^{\ci…
The Galactic Branches as a Possible Evidence for Transient Spiral Arms
Angeles Pérez-Villegas, Gilberto C. Gómez, Bárbara Pichardo
With the use of a background Milky-Way-like potential model, we performed stellar orbital and magnetohydrodynamic (MHD) simulations. As a first experiment, we studied the gaseous r…
Resonant Trapping in the Galactic Disc and Halo and its Relation with Moving Groups
Edmundo Moreno, Barbara Pichardo, William Schuster
With the use of a detailed Milky Way nonaxisymmetric potential, observationally and dynamically constrained, the effects of the bar and the spiral arms in the Galaxy are studied in…
Detecting Triaxiality in the Galactic Dark Matter Halo through Stellar Kinematics II: Dependence on Dark Matter and Gravity Nature
Armando Rojas-Niño, Luis A. Martínez-Medina, Barbara Pichardo +1
Recent studies have presented evidence that the Milky Way global potential may be nonspherical. In this case, the assembling process of the Galaxy may have left long lasting stella…
The Contribution of Spiral Arms to the Thick Disk along the Hubble Sequence
L. A. Martinez-Medina, B. Pichardo, A. Pérez-Villegas +1
The first mechanism invoked to explain the existence of the thick disk in the Milky Way Galaxy, were the spiral arms. Up-to-date work summon several other possibilities that togeth…
