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…
Set them free: extending RAMCOAL to model massive black hole triplets in hydrodynamical simulations of galaxies
Kunyang Li, Ricarda S. Beckmann, Yohan Dubois +1
Massive black hole binaries (MBHBs), and the higher-order multiples produced by repeated galaxy mergers, spend part of their lives in dynamical regimes that cosmological simulation…
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…
Downsizing does not extend to dwarf galaxies: identifying the stellar mass regimes shaped by supernova and AGN feedback
Ilin Lazar, Sugata Kaviraj, Garreth Martin +10
We explore how the fraction of red (quenched) galaxies varies in the dwarf galaxy regime (10^7 MSun < Mstar < 10^9.5 MSun), using a mass-complete sample of ~5900 dwarfs at z<0.15,…
The multimessenger view of Pulsar Timing Array black holes with the Horizon-AGN simulation
Hippolyte Quelquejay Leclere, Kunyang Li, Marta Volonteri +5
We use the Horizon-AGN cosmological simulation to study the properties of supermassive black hole binaries (MBHBs) contributing most to the gravitational wave background (GWB) sign…
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…
