Wandering intermediate-mass black holes and off-nuclear tidal disruption events from early star clusters
Claire E. Williams, Smadar Naoz, Yihao Zhou +9
Off-nuclear tidal disruption events (TDEs) reveal evidence for massive black holes outside galactic centers, but the origins of this wandering population remain uncertain. We inves…
Simulations of Dust Content and Attenuation in Galaxies
Dhruv T. Zimmerman, Jed McKinney, Desika Narayanan +10
Correctly modeling the dust attenuation law in galaxies is essential to properly inferring their growth and physical properties. With the rapid discovery of galaxies by JWST…
Towards robust simulations of the galactic dynamo: a cross-code comparison between Eulerian and Lagrangian schemes
Mark Ivan Ugalino, Benedikt Diemer, Vadim A. Semenov +8
Galactic magnetic fields are thought to be seeded by microscopic processes such as the Biermann battery and are primarily amplified to observed microgauss strengths by dynamo proce…
RIGEL: Ultra-faint dwarf galaxy diversity shaped by inhomogeneous cosmic reionization
Yunwei Deng, Hui Li, Ewald Puchwein +7
Ultra-faint dwarf galaxies (UFDs) are among the smallest and oldest galaxies in the Universe and are widely regarded as relics of cosmic reionization. To investigate how reionizati…
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…
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 model. The system naturally…
