Gas Dynamics in the Central Molecular Zone and its connection with the Galactic Bar
Leonardo Chaves-Velasquez, Gilberto C. Gómez, Ángeles Pérez-Villegas
The innermost region of the Milky Way harbors the central molecular zone (CMZ). This region contains a large amount of molecular gas but a poor star formation rate considering the…
Stellar Orbital Studies in Normal Spiral Galaxies II: Restrictions to Structural and Dynamical parameters on Spiral Arms
Angeles Pérez-Villegas, Bárbara Pichardo, Edmundo Moreno
Making use of a set of detailed potential models for normal spiral galaxies, we analyze the disk stellar orbital dynamics as the structural and dynamical parameters of the spiral a…
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…
Stellar Orbital Studies in Normal Spiral Galaxies I: Restrictions to the Pitch Angle
A. Pérez-Villegas, B. Pichardo, E. Moreno
We built a family of non-axisymmetric potential models for normal non-barred or weakly-barred spiral galaxies as defined in the simplest classification of galaxies: the Hubble sequ…
Pitch Angle Restrictions in Late Type Spiral Galaxies Based on Chaotic and Ordered Orbital Behavior
Angeles Perez-Villegas, Barbara Pichardo, Edmundo Moreno +2
We built models for low bulge mass spiral galaxies (late type as defined by the Hubble classification) using a 3-D self-gravitating model for spiral arms, and analyzed the orbital…
