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…
Redshift Evolution of the Intrinsic Alignments of Early-Type Galaxies and Subhalos in the Horizon Run 5 Simulation
Sanghyeon Han, Motonari Tonegawa, Ho Seong Hwang +8
We investigate the redshift evolution of intrinsic alignments of the shapes of galaxies and subhalos with the large-scale structures of the universe using the cosmological hydrodyn…
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…
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…
Tracing the Formation History of Intrahalo Light with Horizon Run 5
Hyungjin Joo, M. James Jee, Juhan Kim +8
We investigate the formation history of intrahalo light (IHL) using the high-resolution (~1 kpc), large-scale (~Gpc) cosmological hydrodynamical simulation, Horizon Run 5 (HR5). IH…
Star-formation Properties of z ~ 1 Galaxy Clusters and Groups from Horizon Run 5
Seong-Kook Lee, Changbom Park, Juhan Kim +4
Quiescent galaxies are predominantly observed in local galaxy clusters. However, the fraction of quiescent galaxies in high-redshift clusters significantly varies among different c…
Testing Lyman Alpha Emitters and Lyman-Break Galaxies as Tracers of Large-Scale Structures at High Redshifts
Sang Hyeok Im, Ho Seong Hwang, Jaehong Park +21
We test whether Lyman alpha emitters (LAEs) and Lyman-break galaxies (LBGs) can be good tracers of high-z large-scale structures, using the Horizon Run 5 cosmological hydrodynamica…
The Environmental Dependence of the Stellar Mass - Gas Metallicity Relation in Horizon Run 5
Aaron R. Rowntree, Ankit Singh, Fiorenzo Vincenzo +11
Metallicity offers a unique window into the baryonic history of the cosmos, being instrumental in probing evolutionary processes in galaxies between different cosmic environments.…
Spatial Distribution of Intracluster Light versus Dark Matter in Horizon Run 5
Jaewon Yoo, Changbom Park, Cristiano G. Sabiu +11
One intriguing approach for studying the dynamical evolution of galaxy clusters is to compare the spatial distributions among various components, such as dark matter, member galaxi…
Identification of Galaxy Protoclusters Based on the Spherical Top-hat Collapse Theory
Jaehyun Lee, Changbom Park, Juhan Kim +7
We propose a new method for finding galaxy protoclusters that is motivated by structure formation theory and also directly applicable to observations. We adopt the conventional def…
The evolution of the radial gradient of Oxygen abundance in spiral galaxies
M. Mollá, A. I. Díaz, Y. Ascasibar +4
The aim of this work is to present our new series of chemical evolution models computed for spiral and low mass galaxies of different total masses and star formation efficiencies.…
Galactic chemical evolution in hierarchical formation models - I. Early-type galaxies in the local Universe
Matías Arrigoni, Scott C. Trager, Rachel S. Somerville +1
We study the metallicities and abundance ratios of early-type galaxies in cosmological semi-analytic models (SAMs) within the hierarchical galaxy formation paradigm. To achieve thi…
