چکیده

We derive the non-relativistic limit of a massive vector field. show that Cartesian spatial components behave as three identical, non-interacting scalar fields. find classes spherical, cylindrical, and planar self-gravitating solitons in Newtonian limit. The gravitational properties lowest-energy solitons$\mathrm{-}$the potential density field$\mathrm{-}$depend only on net mass soliton particle mass. In particular, these self-gravitating, ground-state are independent distribution energy across field components, indistinguishable from their scalar-field counterparts. Fuzzy Vector Dark Matter models can therefore give rise to halo cores with identical observational ones models. also provide novel hedgehog solutions, which cannot be observed theories. binding is about times weaker than soliton. Finally, we no spherically symmetric exist divergence-free

Dark-matter decays and self-gravitating halos

We consider models in which a dark-matter particle decays to a slightly less massive daughter particle and a noninteracting massless particle. The decay gives the daughter particle a small velocity kick. Selfgravitating dark-matter halos that have a virial velocity smaller than this velocity kick may be disrupted by these particle decays, while those with larger virial velocities will be heated...

Hidden vector dark matter

We show that dark matter could be made of massive gauge bosons whose stability doesn’t require to impose by hand any discrete or global symmetry. Stability of gauge bosons can be guaranteed by the custodial symmetry associated to the gauge symmetry and particle content of the model. The particle content we consider to this end is based on a hidden sector made of a vector multiplet associated to...

Self-Interacting Dark Matter

Spergel and Steinhardt have recently proposed the concept of dark matter with strong self-interactions as a means to address numerous discrepancies between observations of dark matter halos on subgalactic scales and the predictions of the standard collisionless dark matter picture. We review the motivations for this scenario and discuss some recent, successful numerical tests. We also discuss t...

Mirror Matter as Self Interacting Dark Matter

It has been argued that the observed core density profile of galaxies is inconsistent with having a dark matter particle that is collisionless and alternative dark matter candidates which are self interacting may explain observations better. One new class of self interacting dark matter that has been proposed in the context mirror universe models of particle physics is the mirror hydrogen atom ...

Quantum self-gravitating collapsing matter in a quantum geometry

The problem of how space–time responds to gravitating quantum matter in full quantum gravity has been one of the main questions that any program of quantization of gravity should address. Here we analyze this issue by considering the quantization of a collapsing null shell coupled to spherically symmetric loop quantum gravity. We show that the constraint algebra of canonical gravity is Abelian ...
