Non-Axisymmetric Structure in the Satellite Dwarf Galaxy NGC2976: Implications for its Dark/Bright Mass Distribution and Evolution
O. Valenzuela, H. Hernández-Toledo, M. Cano-Díaz +4
We present the result of an extensive search for non-axisymmetric structures in the dwarf satellite galaxy of M81: NGC 2976, using multiwavelength archival observations. The galaxy…
Habitability in Different Milky Way Stellar Environments: a Stellar Interaction Dynamical Approach
Juan J. Jiménez-Torres, Bárbara Pichardo, George Lake +1
Every Galactic environment is characterized by a stellar density and a velocity dispersion. With this information from literature, we simulated flyby encounters for several Galacti…
On the galaxy spiral arms' nature as revealed by rotation frequencies
Santi Roca-Fàbrega, Octavio Valenzuela, Francesca Figueras +4
High resolution N-body simulations using different codes and initial condition techniques reveal two different behaviours for the rotation frequency of transient spiral arms like s…
Comparing Gaseous and Stellar Orbits in a Spiral Potential
Gilberto C. Gómez, Bárbara Pichardo, Marco A. Martos
It is generally assumed that gas in a galactic disk follows closely non self-intersecting periodic stellar orbits. In order to test this common assumption, we have performed MHD si…
