The formation of the brightest cluster galaxy and intracluster light in cosmological N-body simulations with the Galaxy Replacement Technique
Kyungwon Chun, Jihye Shin, Rory Smith +2
We investigate the formation channels of the intracluster light (ICL) and the brightest cluster galaxy (BCG) in clusters at . For this, we perform multi-resolution cosmologica…
Low-Surface-Brightness Galaxies are missing in the observed Stellar Mass Function
Juhan Kim, Jaehyun Lee, Clotilde Laigle +8
We investigate the impact of the surface brightness (SB) limit on the galaxy stellar mass functions (GSMFs) using mock surveys generated from the Horizon Run 5 (HR5) simulation. We…
Properties of Globular Clusters in Galaxy Clusters: Sensitivity from the Formation and Evolution of Globular Clusters
So-Myoung Park, Jihye Shin, Rory Smith +1
We investigate the properties of globular clusters in a galaxy cluster, using the particle tagging method with a semi-analytical approach in a cosmological context. We assume globu…
The First Fall is the Hardest: The Importance of Peculiar Galaxy Dynamics at Infall Time for Tidal Stripping Acting at the Centers of Groups and Clusters
Rory Smith, Paula Calderon-Castillo, Jihye Shin +2
Using dark matter only N-body cosmological simulations, we measure the pericentre distance of dark matter halos on their first infall into group and cluster halos. We find that the…
Unexpected dancing partners: Tracing the coherence between the spin and motion of dark matter halos
Yigon Kim, Rory Smith, Jihye Shin
A recent study conducted using CALIFA survey data (Lee et al, 2019b) has found that the orbital motions of neighbor galaxies are coherent with the spin direction of a target galaxy…
A New Method to Constrain the Appearance and Disappearance of Observed Jellyfish Galaxy Tails
Rory Smith, Jong-Ho Shinn, Stephanie Tonnesen +11
We present a new approach to observationally constrain where the tails of Jellyfish (JF) galaxies in groups and clusters first appear and how long they remain visible with respect…
Spatial distribution of dark matter in and around galaxy clusters traced by galaxies, gas and intracluster stars in a simulated universe
Jihye Shin, Jong Chul Lee, Ho Seong Hwang +5
To understand how well galaxies, gas and intracluster stars trace dark matter in and around galaxy clusters, we use the IllustrisTNG cosmological hydrodynamical simulation and comp…
Comparison of spatial distributions of Intracluster light and Dark Matter
Jaewon Yoo, Jongwan Ko, Cristiano G. Sabiu +7
In a galaxy cluster, the relative spatial distributions of dark matter, member galaxies, gas, and intracluster light (ICL) may connote their mutual interactions over the cluster ev…
Is Abell 2261 a fossil galaxy cluster in a transitional dynamical state?
Hyowon Kim, Jongwan Ko, Rory Smith +5
Abell 2261 (A2661) is a well-studied fossil cluster, but previous studies give contradictory results on its dynamical states, such as its X-ray central entropy and magnitude gap. T…
Formation and Morphology of the First Galaxies in the Cosmic Morning
Changbom Park, Jaehyun Lee, Juhan Kim +8
We investigate the formation and morphological evolution of the first galaxies in the cosmic morning () using the Horizon Run 5 (HR5) simulation. For galaxi…
Tracking Halo Orbits and Their Mass Evolution around Large-scale Filaments
Hannah Jhee, Hyunmi Song, Rory Smith +3
We have explored the dynamical and mass evolution of halos driven by large-scale filaments using a dark matter-only cosmological simulation with the help of a phase-space analysis.…
