제목: Estimating spin parameters ab initio​​​​

Abstract:

We build a model to predict from first principles the properties of major mergers. We predict these from the coalescence of peaks and saddle points in the vicinity of a given larger peak, as one increases the smoothing scale in the initial linear density field as a proxy for cosmic time. Our model allows us to  recover the typical spin brought by mergers: it is of the order of a few tens of percent.​
