Optimal Transport Reconstruction of Baryon Acoustic Oscillations
Farnik Nikakhtar, Ravi K. Sheth, Bruno Lévy +1
A weighted, semi-discrete, fast optimal transport (OT) algorithm for reconstructing the Lagrangian positions of proto-halos from their evolved Eulerian positions is presented. The…
Accurate Baryon Acoustic Oscillations reconstruction via semi-discrete optimal transport
Sebastian von Hausegger, Bruno Lévy, Roya Mohayaee
Optimal transport theory has recently reemerged as a vastly resourceful field of mathematics with elegant applications across physics and computer science. Harnessing methods from…
A fast semi-discrete optimal transport algorithm for a unique reconstruction of the early Universe
Bruno Lévy, Roya Mohayaee, Sebastian von Hausegger
We leverage powerful mathematical tools stemming from optimal transport theory and transform them into an efficient algorithm to reconstruct the fluctuations of the primordial dens…
