Optimal Transport Reconstruction of Biased Tracers in Primordial Non-Gaussian Fields
Farnik Nikakhtar, Ravi K. Sheth, Nikhil Padmanabhan +2
Optimal transport provides an efficient method to infer the displacement of objects by mapping their initial positions to their present-day locations over cosmic time; equivalently…
Weak Lensing Low Multipoles
Albert Bonnefous, Roya Mohayaee
We analyse the low--multipole components of the weak-lensing convergence field in a FLRW universe. The low--multipole convergence field, encodes the largest-angle coherent potentia…
Monge-Ampère gravitating fluids. Least action principles and particle systems
Christian Léonard, Roya Mohayaee
The Monge-Ampère gravitation theory (MAG) was introduced by Brenier in 2011 to obtain an approximate solution of the early Universe reconstruction problem. It is a modification of…
Monge-Ampère gravity, optimal transport theory and their link to the Galileons
Albert Bonnefous, Yann Brenier, Roya Mohayaee
Mathematicians have been proposing for sometimes that Monge-Ampère equation, a nonlinear generalization of the Poisson equation, where trace of the Hessian is replaced by its deter…
Monge Ampère gravity: from the large deviation principle to cosmological simulations through optimal transport
Bruno Lévy, Yann Brenier, Roya Mohayaee
We study Monge-Ampère gravity (MAG) as an effective theory of cosmological structure formation through optimal transport theory. MAG is based on the Monge-Ampère equation, a nonlin…
Path-integral quantization of gravity
R. Mohayaee
We consider the anomalies of gravity in the context of path-integralquantization. We derive the ghost-loop anomalies to all orders in directly from the path-inte…
