A Universal Relation Between Primordial Density-Potential Cross-correlation Coefficient and Spin Factor Distribution
Jun-Sung Moon, Jounghun Lee, Juhan Kim
Recent studies have revealed that the key properties of visible galaxies like their optical sizes, stellar ages, star formation rates and morphologies are closely linked with the a…
Closing the Observational Gap in Cosmic Dynamics: AI-Enabled Reconstruction of the Universe's Vorticity and Rotational Flow Morphology
Ziyong Wu, Xu Xiao, Fuyu Dong +7
The cosmic vorticity field, an essential tracer of nonlinear structure formation, has remained observationally inaccessible because transverse galaxy motions are difficult to measu…
Intracluster Light as a Probe for Dark Matter: Exploring Self-interacting Dark Matter and Cold Dark Matter with C-EAGLE Sims
Jaewon Yoo, Ellen L. Sirks, Cristiano G. Sabiu +5
We assess whether intracluster light (ICL) can serve as an observational discriminator of dark matter physics. The self-interacting dark matter (SIDM) model has gained increasing a…
Revealing Hidden Cosmic Flows through the Zone of Avoidance with Deep Learning
Alexandra Dupuy, Donghui Jeong, Sungwook E. Hong +3
We present a refined deep-learning-based method to reconstruct the three-dimensional dark matter density, gravitational potential, and peculiar velocity fields in the Zone of Avoid…
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…
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…
