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…
Cluster-counterpart Voids: Void Identification from Galaxy Density Field
Junsup Shim, Changbom Park, Juhan Kim +1
We identify cosmic voids from galaxy density fields under the theory of void-cluster correspondence. We extend the previous novel void-identification method developed for the matte…
Forecasts for WEAVE-QSO: 3D clustering and connectivity of critical points with Lyman- tomography
Katarina Kraljic, Clotilde Laigle, Christophe Pichon +12
The upcoming WEAVE-QSO survey will target a high density of quasars over a large area, enabling the reconstruction of the 3D density field through Lyman- tomography over unprece…
Identification of Cosmic Voids as Massive Cluster Counterparts
Junsup Shim, Changbom Park, Juhan Kim +1
We develop a method to identify cosmic voids from the matter density field by adopting a physically-motivated concept that voids are the counterpart of massive clusters. To prove t…
The clustering of critical points in the evolving cosmic web
Junsup Shim, Sandrine Codis, Christophe Pichon +2
Focusing on both small separations and Baryonic Acoustic Oscillation scales, the cosmic evolution of the clustering properties of peak, void, wall, and filament-type critical point…
Dependence of the Substructure Abundance on the Orientation Coherence of the Halo Tidal Field
Junsup Shim, Jounghun Lee
A numerical evidence for the dependence of the substructure abundance of cluster halos on the orientation coherence of the surrounding tidal fields is presented. Applying the adapt…
An observational detection of the bridge effect of void filaments
Junsup Shim, Jounghun Lee, Fiona Hoyle
The bridge effect of void filaments is a phrase coined by Park & Lee (2009b) to explain the correlations found in a numerical experiment between the luminosity of the void galaxies…
Breaking the Cosmic Degeneracy between Modified Gravity and Massive Neutrinos with the Cosmic Web
Junsup Shim, Jounghun Lee, Marco Baldi
In a recent work, Baldi et al. highlighted the issue of cosmic degeneracies, consisting in the fact that the standard statistics of the large-scale structure might not be sufficien…
Massive Gravity wrapped in the Cosmic Web
Junsup Shim, Jounghun Lee, Baojiu Li
We study how the filamentary pattern of the cosmic web changes if the true gravity deviates from the general relativity (GR) on the large scale. The f(R) gravity whose strength is…
Dark Sector Coupling Bends the Superclusters
Junsup Shim, Jounghun Lee
The galaxy clusters exhibit noticeably anisotropic pattern in their clustering, which is vividly manifested by the presence of rich filament-like superclusters. The more anisotropi…
