« How does the cosmic web impact assembly bias? »

Corentin Cadiou
PhD student - Institut d'Astrophysique de Paris (Paris, France)

Recent development have shown that the halo assembly is in-
fluenced by the large scale structure of the cosmic web, resulting
in the so called assembly bias. Using an extension of the excursion
set theory constrained to the presence of a filament type structure,
I will show how one can compute the accretion rate and formation
time of halos and recover that distinct gradients for different quan-
tities appear. I will argue that this effect can not be explained by
a local rescaling of the density but instead encodes the intrinsic
anisotropy of the large scale environment.
