Kinematic scaling of thin and thick discs from SAMI to NewHorizon
Sree Oh, J. K. Jang, Giulia Santucci +8
We revisit the relation between disc stellar mass and disc velocity dispersion (M_*-Ï_e) and extend it to thin and thick subcomponents using orbit-based dynamical models of 161 SA…
Zippers and Twisters: Planes of Satellite Galaxies Emerge from Whirling and Shocking Gas Streams in the Cosmic Web
Janvi P. Madhani, Charlotte Welker, Sneha Nair +7
We investigate dwarf satellite systems around Milky Way analogs in the NewHorizon simulation. Using simple estimators limiting over-detection, we identify planes of satellites comp…
The Critical Mass in Galaxy Evolution
Preetish K. Mishra, Changbom Park, Jaehyun Lee +4
We investigate the physical origin of critical mass, a threshold where many galaxy properties and scaling relations undergo fundamental transitions, using the Horizon Run 5 simulat…
The influence of galaxy mergers, black-hole growth, and gas processes on the evolution of the stellar mass-gas metallicity relation of galaxies in different cosmic environments
Aaron R. Rowntree, Fiorenzo Vincenzo, Ankit Singh +3
We study the impact of supermassive black hole (SMBH) growth, , major and minor galaxy mergers, and gas processes, on the average gas metallic…
The Role of Large-Scale Environment in Shaping the Stellar Mass-Gas Metallicity Relation Across Time
Aaron R. Rowntree, Fiorenzo Vincenzo, Ankit Singh +8
We study the stellar mass-gas metallicity relation (MZR) which shows a significant scatter for a fixed stellar mass. By defining global environments, nodes, filaments, and voids wi…
On the Origin of Intracluster Light based on the High-resolution Simulation, NewCluster
Seyoung Jeon, Emanuele Contini, San Han +11
Intracluster light (ICL) is a key component of galaxy clusters, with the potential to trace their dynamical assembly histories and the underlying dark matter distribution. Despite…
