Dynamic Zoom Simulations of structure formation beyond standard cosmology
Riccardo Zangarelli, Marco Baldi, Federico Marinacci +1
The paper introduces a Dynamic Zoom Simulations (DZS) technique that reduces resolution outside an observer’s lightcone to speed up large‑scale cosmological simulations, and valida…
A Universal Dance of Galactic Disks: Ubiquitous Precession and Its Implications
Yuan Wang, Xiong Luo, Huiyuan Wang +5
Precession is a very common phenomenon for small-scale astronomical objects. However, the precession of galactic disks, occurring on a scale larger than kilo-parsec, has barely bee…
The Entangling of Supernova Feedback Impacts with Coarsening Simulation Resolution
Eric Zhang, Laura V. Sales, Thales A. Gutcke +11
It is often understood that supernova (SN) feedback in galaxies is responsible for regulating star formation (SF) and generating gaseous outflows. However, a detailed look at their…
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…
Age and metallicity of low-mass galaxies: from their centres to their stellar halos
Elisa A. Tau, Antonela Monachesi, Facundo A. Gómez +5
We aim to analyse the metallicity and the ages of the stellar halos of low-mass galaxies to better understand their formation history. We use 17 simulated low-mass galaxies from th…
