Impact of bar resonances in the velocity-space distribution of the solar neighbourhood stars in a self-consistent -body Galactic disc simulation
Tetsuro Asano, Michiko S. Fujii, Junichi Baba +3
The velocity-space distribution of the solar neighbourhood stars shows complex substructures. Most of the previous studies use static potentials to investigate their origins. Inste…
DeepGalaxy: Deducing the Properties of Galaxy Mergers from Images Using Deep Neural Networks
Maxwell X. Cai, Jeroen Bédorf, Vikram A. Saletore +4
Galaxy mergers, the dynamical process during which two galaxies collide, are among the most spectacular phenomena in the Universe. During this process, the two colliding galaxies a…
Bonsai-SPH: A GPU accelerated astrophysical Smoothed Particle Hydrodynamics code
Jeroen Bédorf, Simon Portegies Zwart
We present the smoothed-particle hydrodynamics simulation code, Bonsai-SPH, which is a continuation of our previously developed gravity-only hierarchical -body code (called Bons…
Modeling the Milky Way as a Dry Galaxy
Michiko S. Fujii, Jeroen Bédorf, Junichi Baba +1
We construct a model for the Milky Way Galaxy composed of a stellar disc and bulge embedded in a dark-matter halo. All components are modelled as -body systems with up to 8 bill…
The dynamics of stellar disks in live dark-matter halos
Michiko S. Fujii, Jeroen Bédorf, Junichi Baba +1
Recent developments in computer hardware and software enable researchers to simulate the self-gravitating evolution of galaxies at a resolution comparable to the actual number of s…
The Effect of Many Minor Mergers on the Size Growth of Compact Quiescent Galaxies
Jeroen Bédorf, Simon Portegies Zwart
Massive galaxies with a half-mass radius <~ 1kpc are observed in the early universe (z~>2), but not in the local universe. In the local universe similar-mass (within a factor of tw…
