It is well-known that Dark Matter (DM) inside a satellite galaxy orbiting a host halo
experiences a tidal potential. If DM is ultra-light, given its wave-like nature, one expects it to …

Initially applied to the scalar case, we extend the applicability of the multi-field generalization
with angular momentum of bosonic stars to the vector case, in order to obtain new …

Rotating fermion-boson stars are hypothetical celestial objects that consist of both fermionic
and bosonic matter interacting exclusively through gravity. Bosonic fields are believed to …

Abstract Using Low Brightness Surface Galaxies (LBSG) rotational curves we inferred the
free parameters of ℓ-boson stars as a dark matter component. The ℓ-boson stars are …

We study the Dirac equation minimally coupled to general relativity using quantum field
theory and the semiclassical gravity approximation. Previous studies of the Einstein-Dirac …

We study the linear stability of nonrelativistic ℓ-boson stars, describing static, spherically
symmetric configurations of the Schrödinger-Poisson system with multiple wave functions …

In previous work we analyzed the linear stability of nonrelativistic ℓ-boson stars with respect
to radial modes and showed that ground state configurations are stable with respect to these …

The gravitational deflection of light is a critical test of modified theories of gravity. A few years
ago, Gibbons and Werner introduced a definition of the deflection angle based on the Gauss …

We revisit the cosmic evolution of the energy density of a quantized free scalar field and
assess under what conditions the particle production and classical field approximations …

Boson Stars are, at present, hypothetical compact stellar objects whose existence, however,
could resolve several enigmas of current astrophysics. If they exist, either as independent …
