The cosmology dependence of galaxy clustering and lensing from a hybrid $N$-body-perturbation theory model

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Nickolas Kokron, Joseph DeRose, Shi-Fan Chen, Martin White, Risa H. Wechsler | Summary: We implement a model for the two-point statistics of biased tracers that combines dark matter dynamics from $N$-body simulations with an analytic Lagrangian bias expansion. Using Aemulus, a suite of $N$-body simulations built […]

Anomalies in the gravitational recoil of eccentric black-hole mergers with unequal mass ratios

Posted by klaurent Cambridge

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Miren Radia, Ulrich Sperhake, Emanuele Berti, Robin Croft, | Summary: The radiation of linear momentum imparts a recoil (or "kick") to the center of mass of a merging black hole binary system. Recent numerical relativity calculations have shown that eccentricity can lead to an approximate 25% increase […]
