Measuring nonlocal Lagrangian peak bias
Matteo Biagetti, Kwan Chuen Chan, Vincent Desjacques +1
We investigate nonlocal Lagrangian bias contributions involving gradients of the linear density field, for which we have predictions from the excursion set peak formalism. We begin…
Helmholtz Decomposition of the Lagrangian Displacement
Kwan Chuen Chan
Lagrangian displacement field is the central object in Lagrangian perturbation theory (LPT). LPT is very successful at high redshifts, but it performs poorly at low redshifts d…
Bias deconstructed: Unravelling the scale dependence of halo bias using real space measurements
Aseem Paranjape, Emiliano Sefusatti, Kwan Chuen Chan +3
We explore the scale dependence of halo bias using real space cross-correlation measurements in N-body simulations and in Pinocchio, an algorithm based on Lagrangian Perturbation T…
