Going off the (momentum) grid: A simple implementation of noncold relics in linear Boltzmann solvers
Arad Nasiri, Murali Saravanan, Caio B. de S. Nascimento
Linear Boltzmann solvers typically evolve the perturbations of noncold relics, such as massive neutrinos or hot subcomponents of the dark matter, on a momentum grid, often switchin…

Kinetic Theory of the EFTofLSS : A Halo-Based Approach
Om Kishor Hebbar, Caio B. de S. Nascimento, Arka Banerjee
The Effective Field Theory of Large Scale Structure (EFTofLSS) provides a coarse-grained description of the non-linear gravitational clustering of dark matter, in which the effects…
