Kinetic Theory of the EFTofLSS : A Halo-Based Approach
Om Kishor Hebbar, Caio B. de S. Nascimento, Arka Banerjee
The Effective Field Theory of Large Scale Structure (EFTofLSS) provides a coarse-grained description of the non-linear gravitational clustering of dark matter, in which the effects…

Lagrangian Bias as a Gaussian Random Field
Arka Banerjee
Halo bias is typically treated as a set of coefficients in a perturbative expansion. We show instead that every point in a Gaussian density field has a well-defined scale-independe…

Joint analysis of small-scale galaxy clustering and galaxy--galaxy lensing from BOSS galaxies
Wenhao Gao, Zhenjie Liu, Zhongxu Zhai +8
We present a joint analysis of galaxy clustering and galaxy--galaxy lensing measurements from BOSS galaxies using a simulation-based emulation method combined with a halo occupatio…
