CTree: Branch-wise compatible merger tree builder

Jinsu Rhee, Christophe Pichon, Yohan Dubois

We introduce a merger tree builder, CTree. Its key feature is the identification of progenitors using the evolutionary information encoded in object branches, rather than relying s…

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…

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…

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…

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…

Introducing NewCluster: the first half of the history of a high-resolution cluster simulation

San Han, Sukyoung K. Yi, Yohan Dubois +8

We introduce NewCluster, a new high-resolution cluster simulation designed to serve as the massive halo counterpart of the modern cosmological galaxy evolution framework. The zoom-…

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…

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…

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…

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…

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…

Black hole spin evolution across cosmic time from the NewHorizon simulation

Ricarda S. Beckmann, Yohan Dubois, Marta Volonteri +8

Astrophysical black holes (BHs) have two fundamental properties: mass and spin. While the mass-evolution of BHs has been extensively studied, much less work has been done on predic…

Emergence of the Galaxy Morphology-Star Formation Activity-Clustercentric Radius Relations in Galaxy Clusters

Sungwook E. Hong, Changbom Park, Preetish K. Mishra +7

We investigate when and how the relations of galaxy morphology and star forming activity with clustercentric radius become evident in galaxy clusters. We identify 162 galaxy cluste…

Exploring lenticular galaxy formation in field environments using NewHorizon: evidence for counter-rotating gas accretion as a formation channel

Seongbong Han, J. K. Jang, Emanuele Contini +9

The formation pathways of lenticular galaxies (S0s) in field environments remain a matter of debate. We utilize the cosmological hydrodynamic simulation, NewHorizon, to investigate…
