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…
The causal effect of cosmic filaments on dark matter halos
Anatole Storck, Corentin Cadiou, Oscar Agertz +1
The way in which the large-scale cosmic environment affects galactic properties is not yet understood. Dark matter halos, which embed galaxies, initially evolve following linear th…
The AGORA High-resolution Galaxy Simulations Comparison Project IV: Halo and Galaxy Mass Assembly in a Cosmological Zoom-in Simulation at
Santi Roca-Fàbrega, Ji-hoon Kim, Joel R. Primack +25
In this fourth paper from the AGORA Collaboration, we study the evolution down to redshift and below of a set of cosmological zoom-in simulations of a Milky Way mass galaxy b…
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…
Evolution of cosmic filaments in the MTNG simulation
Daniela Galárraga-Espinosa, Corentin Cadiou, Céline Gouin +11
We present a study of the evolution of cosmic filaments across redshift with an emphasis on some important properties: filament lengths, growth rates, and radial profiles of galaxy…
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…
The causal effect of environment on halo mass and concentration
Corentin Cadiou, Andrew Pontzen, Hiranya V. Peiris +1
Understanding the impact of environment on the formation and evolution of dark matter halos and galaxies is a crucial open problem. Studying statistical correlations in large simul…
Angular momentum evolution can be predicted from cosmological initial conditions
Corentin Cadiou, Andrew Pontzen, Hiranya V. Peiris
The angular momentum of dark matter haloes controls their spin magnitude and orientation, which in turn influences the galaxies therein. However, the process by which dark matter h…
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…
How does the cosmic web impact assembly bias?
M. Musso, C. Cadiou, C. Pichon +3
The mass, accretion rate and formation time of dark matter haloes near proto-filaments (identified as saddle points of the potential) are analytically predicted using a conditional…
