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…
The impact of AGN feedback on galaxy intrinsic alignments in the Horizon simulations
Adam Soussana, Nora Elisa Chisari, Sandrine Codis +7
The intrinsic correlations of galaxy shapes and orientations across the large-scale structure of the Universe are a known contaminant to weak gravitational lensing. They are known…
Statistics of cosmic density profiles from perturbation theory
Francis Bernardeau, Christophe Pichon, Sandrine Codis
The joint probability distribution function (PDF) of the density within multiple concentric spherical cells is considered. It is shown how its cumulant generating function can be o…
It takes two to know one: Computing accurate one-point PDF covariances from effective two-point PDF models
Cora Uhlemann, Oliver Friedrich, Aoife Boyle +4
One-point probability distribution functions (PDFs) of the cosmic matter density are powerful cosmological probes that extract non-Gaussian properties of the matter distribution an…
Back in the saddle: Large-deviation statistics of the cosmic log-density field
Cora Uhlemann, Sandrine Codis, Christophe Pichon +2
We present a first principle approach to obtain analytical predictions for spherically-averaged cosmic densities in the mildly non-linear regime that go well beyond what is usually…
Bulge formation inside quiescent lopsided stellar disks: connecting accretion, star formation and morphological transformation in a z ~ 3 galaxy group
Boris S. Kalita, Emanuele Daddi, Frederic Bournaud +10
We present well-resolved near-IR and sub-mm analysis of the three highly star-forming massive () galaxies within the core of the RO-1001 galaxy group at $\…
