# Precision measurement of the local bias of dark matter halos

@article{Lazeyras2015PrecisionMO, title={Precision measurement of the local bias of dark matter halos}, author={Titouan Lazeyras and Christian Wagner and Tobias Baldauf and Fabian Schmidt}, journal={Journal of Cosmology and Astroparticle Physics}, year={2015}, volume={2016}, pages={018 - 018} }

We present accurate measurements of the linear, quadratic, and cubic local bias of dark matter halos, using curved “separate universe” N-body simulations which effectively incorporate an infinite-wavelength overdensity. This can be seen as an exact implementation of the peak-background split argument. We compare the results with the linear and quadratic bias measured from the halo-matter power spectrum and bispectrum, and find good agreement. On the other hand, the standard peak-background…
