RAMSES-yOMP: Performance Optimizations for the Astrophysical Hydrodynamic Simulation Code RAMSES
San Han, Yohan Dubois, Jaehyun Lee +3
Developing an efficient code for large, multiscale astrophysical simulations is crucial in preparing the upcoming era of exascale computing. RAMSES is an astrophysical simulation c…
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…
ODIN: Strong Clustering of Protoclusters at Cosmic Noon
Vandana Ramakrishnan, Kyoung-Soo Lee, Nicole Firestone +15
The One-hundred-deg DECam Imaging in Narrowbands (ODIN) survey is carrying out a systematic search for protoclusters during Cosmic Noon, using Ly-emitting galaxies (LAEs) as…
Galaxy populations in protoclusters at cosmic noon
Moira Andrews, M. Celeste Artale, Ankit Kumar +20
We investigate the physical properties and redshift evolution of simulated galaxies residing in protoclusters at cosmic noon, to understand the influence of the environment on gala…
Inferring Cosmological Parameters on SDSS via Domain-Generalized Neural Networks and Lightcone Simulations
Jun-Young Lee, Ji-hoon Kim, Minyong Jung +6
We present a proof-of-concept simulation-based inference on and from the SDSS BOSS LOWZ NGC catalog using neural networks and domain generalization techniques w…
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…
ODIN: Identifying Protoclusters and Cosmic Filaments Traced by Ly-emitting Galaxies
Vandana Ramakrishnan, Kyoung-Soo Lee, Maria Celeste Artale +22
To understand the formation and evolution of massive cosmic structures, studying them at high redshift, in the epoch when they formed the majority of their mass is essential. The O…
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…
Understanding the Formation and Evolution of Dark Galaxies in a Simulated Universe
Gain Lee, Ho Seong Hwang, Jaehyun Lee +2
We study the formation and evolution of dark galaxies using the IllustrisTNG cosmological hydrodynamical simulation. We first identify dark galaxies with stellar-to-total mass rati…
