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_*-σ_e) and extend it to thin and thick subcomponents using orbit-based dynamical models of 161 SAM…
Rapid growth in a dual AGN during a gas-rich merger at z~4.5
Hyewon Suh, Roberto Decarli, Emanuele Paolo Farina +15
The late stages of galaxy mergers - when two supermassive black holes (SMBHs) reach kiloparsec-scale separations - represent a critical phase for understanding SMBH growth, galaxy…
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,…
Statistics of the projected angles between the black-hole spin and the host-galaxy rotation axes from NewHorizon
Sebastien Peirani, Yasushi Suto, Clotilde Laigle +3
Understanding the alignment between AGN jets and their host galaxies is crucial for interpreting AGN unification models, jet feedback processes, and the co-evolution of galaxies an…
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…
On the Origin of Gas-stripping of Galaxies in Group Environments
Jinsu Rhee, Christophe Pichon, Yohan Dubois +12
We investigate how low-mass group environments () influence the gas content of their satellite galaxies with using…
Stellar halos of bright central galaxies II: Scaling relations, colors and metallicity evolution with redshift
Emanuele Contini, Marilena Spavone, Rossella Ragusa +2
We study the formation and evolution of stellar halos (SHs) around bright central galaxies (BCGs), focusing on their scaling relations, colors, and metallicities across cosmic time…
The dwarf stellar mass function in different environments and the lack of a generic missing dwarfs problem in ΛCDM
Ilin Lazar, Sugata Kaviraj, Garreth Martin +9
We combine deep photometric data in the COSMOS and XMM-LSS fields with high-resolution cosmological hydrodynamical simulations to explore two key questions: (1) how does the galaxy…
How Dust Models Shape High-z Galaxy Morphology: Insights from the NewCluster Simulation
Gyeong-Hwan Byun, J. K. Jang, Zachary P. Scofield +10
Dust plays a pivotal role in shaping the observed morphology of galaxies. While traditional cosmological simulations often assume a fixed dust-to-gas (DTG) or dust-to-metal (DTM) m…
Born to be Starless: Revisiting the Missing Satellite Problem
Seyoung Jeon, Sukyoung K. Yi, Emanuele Contini +6
The massive Local Group galaxies both host substantially fewer satellites than the subhalos expected from the cold dark matter paradigm, and the recent investigations have highligh…
Dissecting the formation of gas-versus-star counter-rotating galaxies from the NewHorizon simulation
S. Peirani, Y. Suto, S. Han +5
(Reduced)Using the NewHorizon simulation, we have studied ten gas-versus-star counter-rotating galaxies in field environments with a stellar mass of M*~[1-5]x10^10 Msun. For all of…
2D light distributions of dwarf galaxies -- key tests of the implementation of physical processes in simulations
Aaron Watkins, Garreth Martin, Sugata Kaviraj +5
Cosmological simulations provide much of the theoretical framework within which we interpret extragalactic observations. However, even if a given simulation reproduces the integrat…
Formation pathways of the compact stellar systems
J. K. Jang, Sukyoung K. Yi, Soo-Chang Rey +6
The formation pathways of compact stellar systems (CSSs) are still under debate. We utilize the \NH\ simulation to investigate the origins of such objects in the field environment.…
Feeding Hidden Monsters: a Super-Eddington accreting Black Hole ~1.5 Gyr after the Big Bang
Hyewon Suh, Julia Scharwächter, Emanuele Paolo Farina +13
Recent James Webb Space Telescope (JWST) observations have revealed a surprisingly abundant population of faint, dusty active galactic nuclei (AGNs) at z~4-7. Together with the pre…
Galaxies with grains: unraveling dust evolution and extinction curves with hydrodynamical simulations
Yohan Dubois, Francisco Rodríguez Montero, Corentin Guerra +6
We introduce a model for dust evolution in the RAMSES code for simulations of galaxies with a resolved multiphase interstellar medium. Dust is modelled as a fluid transported with…
Cosmic evolution of black hole-spin and galaxy orientations: clues from the NewHorizon and Galactica simulations
Sebastien Peirani, Yasushi Suto, Ricarda S. Beckmann +10
(Reduced) Using the recent cosmological high-resolution zoom-in simulations, NewHorizon and Galactica, in which the evolution of black hole spin is followed on the fly, we have tra…
The formation of cores in galaxies across cosmic time -- the existence of cores is not in tension with the LCDM paradigm
R. A. Jackson, S. Kaviraj, S. K. Yi +9
The `core-cusp' problem is considered a key challenge to the LCDM paradigm. Halos in dark matter only simulations exhibit `cuspy' profiles, where density continuously increases tow…
