From matter to galaxies: General relativistic bias for the one-loop bispectrum
Juan Calles, Lina Castiblanco, Jorge Noreña +1
We write down the Lagrangian bias expansion in general relativity up to 4th order in terms of operators describing the curvature of an early-time hypersurface for comoving observer…

Large scale structures: from inflation to today: a brief report
Lina Castiblanco, Radouane Gannouji, Clément Stahl
We briefly review some selected topics gravitating around large scale structures. We derive from inflation the evolution of dark matter perturbations. The stress is put on the non-…

Relativistic cosmological large scale structures at one-loop
Lina Castiblanco, Radouane Gannouji, Jorge Noreña +1
The large scale structure bispectrum in the squeezed limit couples large with small scales. Since relativity is important at large scales and non-linear loop corrections are import…
