Effects of Resolution and Local Stability on Galactic Disks: Halo Resolution and Softening on Bar Formation
SungWon Kwak, Ivan Minchev, Matthias Steinmetz +1
Using N-body simulations, we examine the impact of dark matter (DM) halo resolution and gravitational softening on bar formation. We generate isolated disk-halo systems with fixed…
SMUGGLE-Ring: Evolutionary link between nuclear star cluster and nuclear disk
SungWon Kwak, Mathias Schultheis, Ivan Minchev +8
We present a high-resolution hydrodynamical simulation of the formation and evolution of nuclear structures in a Milky Way-mass galaxy using the SMUGGLE multiphase ISM and stellar…
The SMUGGLE-Ring project: Bar and bulge effects on nuclear disk and ring formation
SungWon Kwak, Federico Marinacci, Matthias Steinmetz +8
We present the first results from the SMUGGLE-Ring project, a suite of simulations employing the SMUGGLE ISM and stellar feedback model to explore nuclear structures in Milky Way-m…
On the Use of Field RR Lyrae as Galactic Probes -- VIII. Early Formation of the Galactic Spheroid
G. Bono, V. F. Braga, M. Fabrizio +54
We introduce a new photometric catalog of RR Lyrae variables (RRLs, 300,000) mainly based on data available in public datasets. We also present the largest and most homogeneo…
