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…

On the Possibility that Ultra-Light Boson halos host and form Super-massive Black Holes

Ana Avilez-Lopez, Luis Padilla-Albores Luis, Tula Bernal-Marin +1

Several observations suggest the existence of super-massive black holes (SMBH) at the centers of giant galaxies. However the mechanism under which these objects form remains non co…

Energy Balance of a Bose Gas in Curved Spacetime

Tonatiuh Matos, Ana Avilez, Tula Bernal +1

Classical solutions of the Klein-Gordon (KG) equation are used in astrophysics to model galactic halos of scalar field dark matter and compact objects such as cores of neutron star…
