Squeezing the halo bispectrum: a test of bias models
Azadeh Moradinezhad Dizgah, Kwan Chuen Chan, Jorge Noreña +2
We study the halo-matter cross bispectrum in the presence of primordial non-Gaussianity of the local type. We restrict ourselves to the squeezed limit, for which the calculation ar…
Effective Window Function for Lagrangian Halos
Kwan Chuen Chan, Ravi K. Sheth, Roman Scoccimarro
The window function for protohalos in Lagrangian space is often assumed to be a tophat in real space. We measure this profile directly and find that it is more extended than a toph…
Halo Profile Evolution and Velocity Bias
Kwan Chuen Chan
We propose a simple model that elucidates the generation of halo velocity bias. The fluid equation approximation is often adopted in modelling the evolution of the halo density fie…
