Could primordial galactic Magnetic Fields be generated by Charged Ultra-Light Boson Dark Matter?
M. Hernandez, A. Avilez-Lopez, T. Matos
In this work we study the possibility that primordial magnetic fields observed in galaxies could be produced by a dark matter halo made of charged ultra-light bosons. In the model,…

Head-on collision of multi-state ultralight BEC dark matter configurations
F. S. Guzman, Ana Avilez-Lopez
Density profiles of ultralight Bose-Condensate dark matter inferred from numerical simulations of structure formation, ruled by the Gross-Pitaevskii-Poisson (GPP) system of equatio…

Dynamical Systems Analysis in Post-Friedmann Parametrizations of Modified Theories of Gravity
Abril Suárez, Ana Avilez, David Tamayo +2
We carry out a dynamical analysis of first order perturbations for Cold Dark Matter, Cold Dark Matter, and a couple of Modified Gravity models using the Parametrized Post-Fried…
