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…

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…

Probing cosmology via the clustering of critical points

Junsup Shim, Christophe Pichon, Dmitri Pogosyan +5

Exclusion zones in the cross-correlations between critical points (peak-void, peak-wall, filament-wall, filament-void) of the density field define quasi-standard rulers that can be…

The effects of non-linearity on the growth rate constraint from velocity correlation functions

Motonari Tonegawa, Stephen Appleby, Changbom Park +2

The two-point statistics of the cosmic velocity field, measured from galaxy peculiar velocity (PV) surveys, can be used as a dynamical probe to constrain the growth rate of large-s…

On the Effects of Local Environment on Active Galactic Nucleus (AGN) in the Horizon Run 5 Simulation

Ankit Singh, Changbom Park, Ena Choi +6

We use the Horizon Run 5 cosmological simulation to study the effect of galaxy intrinsic properties and the local environment on AGNs characterized by their threshold of the accret…
