Ruling out unitary Fermi gas of neutrinos as galactic dark matter
Andrés Aceña
We investigate the possibility that galactic dark matter could be interacting fermions in the neutrino mass range. Assuming that galactic halos behave like a fluid in hydrostatic a…

No-go theorem for static spherically symmetric configurations composed of two charged pressureless fluid species
Andrés Aceña, Bruno Cardin Guntsche, Ivan Gentile de Austria
We present a no-go theorem for spherically symmetric configurations of two charged fluid species in equilibrium. The fluid species are assumed to be dusts, that is, perfect fluids…

No-go theorem for static configurations of two charged dust species
Andrés Aceña, Bruno Cardin Guntsche, Ivan Gentile de Austria
We consider static spacetimes with no specific spacial symmetry where the matter content consists of two charged dust species. This comes motivated by the fact that static configur…
