The impact of evolving cosmic filaments on mass and spin evolution of dark matter halos
Hannah Jhee, Hyunmi Song, Clotilde Laigle +3
The evolution of galaxies is closely tied to that of their host dark matter halos, which is in turn strongly modulated by the surrounding large-scale environment. Cosmic filaments…
ODIN: Rest-frame Optical Morphologies and Star Formation Activity of Lyα Emitters at z=2.4, 3.1, and 4.5
Sang Hyeok Im, Ho Seong Hwang, Jeong Hwan Lee +19
We analyze the rest-frame optical (~8000 Å) morphologies and star formation activity of Lyα emitters (LAEs) at redshifts , , and , identified in the ODIN survey. To…
Which filaments matter: the relative scalings of anisotropic infall
Junsup Shim, Dmitri Pogosyan, Myoungwon Jeon +1
Dark-matter haloes do not form in isolation but within the surrounding cosmic web. By the time a halo begins to collapse, its larger-scale environment has typically collapsed along…
Non-Gaussian Expansion of Minkowski Tensors in Redshift Space
Stephen Appleby, Christophe Pichon, Pravabati Chingangbam +2
This paper focuses on extending the use of Minkowski Tensors to analyze anisotropic signals in cosmological data, focusing on those introduced by redshift space distortion. We deri…
The Topology of Rayleigh-Levy Flights in Two Dimensions
Reginald Christian Bernardo, Stephen Appleby, Francis Bernardeau +1
Rayleigh-Lévy flights are simplified cosmological tools which capture certain essential statistical properties of the cosmic density field, including hierarchical structures in hig…
Large-scale geometry and topology of gas fields: Effects of AGN and stellar feedback
Carlo Schimd, Katarina Kraljic, Romeel Davé +1
Feedback from stars and active galactic nuclei (AGNs) primarily affects the formation and evolution of galaxies and the circumgalactic medium, leaving some kind of imprint on large…
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…
The statistics of Rayleigh-Levy flight extrema
Francis Bernardeau, Christophe Pichon
Rayleigh-Levy flights have played a significant role in cosmology as simplified models for understanding how matter distributes itself under gravitational influence. These models a…
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…
Estimating major merger rates and spin parameters ab initio via the clustering of critical events
Corentin Cadiou, Eric Pichon-Pharabod, Christophe Pichon +1
We build a model to predict from first principles the properties of major mergers. We predict these from the coalescence of peaks and saddle points in the vicinity of a given large…
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…
When do cosmic peaks, filaments or walls merge? A theory of critical events in a multi-scale landscape
Corentin Cadiou, Christophe Pichon, Sandrine Codis +5
The merging rate of cosmic structures is computed, relying on the Ansatz that they can be predicted in the initial linear density field from the coalescence of critical points with…
Beyond Kaiser bias: mildly non-linear two-point statistics of densities in distant spheres
C. Uhlemann, S. Codis, J. Kim +5
Simple parameter-free analytic bias functions for the two-point correlation of densities in spheres at large separation are presented. These bias functions generalize the so-called…
