My primary scientific interest is in studying both dynamical and secular evolution of disk galaxies.
With the aim to understands the mechanisms of formation galactic spiral structure and generation and evolution
of bars I have been working on N-body/hydrodynamical simulations of disk galaxies.
Several examples from my various studies can be found below.
Spiral structure in a galactic gaseous disk driven by non-axisymmetric DM halo
By means of 3D hydrodynamical simulations, we show that spiral density waves, penetrating in the gas through the outer Lindblad resonance, can indeed give rise to relatively regular patterns outside the bright optical stellar disk (white circle in the center).
N-body simulation of double nested bars in stellar disk.
Fly-by around the Milky Way-type galaxy with X-shaped boxy peanut pseudo bulge. N-body simulation also include structures in the Dark matter halo with initial conditions from Via Lactea cosmological simulation.
