Nonlinear cosmological structure with ultralight bosons via modified gravity

Autor: Stefany G. Medellin-Gonzalez, Alma X. Gonzalez-Morales, L. Arturo Ureña-López

Ultra-light bosons as dark matter has become a model of major interest in Cosmology, due to the possible imprint of a distinct signature in the cosmic structure both at the linear and non-linear scales. In this work we show that the equations of moti
