Constraint of Void Bias on Primordial non-Gaussianity
Kwan Chuen Chan, Nico Hamaus, Matteo Biagetti
We study the large-scale bias parameter of cosmic voids with primordial non-Gaussian (PNG) initial conditions of the local type. In this scenario, the dark matter halo bias exhibit…
Shot noise and biased tracers: a new look at the halo model
Dimitry Ginzburg, Vincent Desjacques, Kwan Chuen Chan
Shot noise is an important ingredient to any measurement or theoretical modeling of discrete tracers of the large scale structure. Recent work has shown that the shot noise in the…
Non-local Lagrangian bias
Ravi K. Sheth, Kwan Chuen Chan, Roman Scoccimarro
Halos are biased tracers of the dark matter distribution. It is often assumed that the patches from which halos formed are locally biased with respect to the initial fluctuation fi…
