Journal ArticleDOI
Metric affine gauge theory of gravity: Field equations, Noether identities, world spinors, and breaking of dilation invariance
TL;DR: In this article, the authors present explicit models for a symmetry breakdown in the cases of the Weyl (or homothetic) group, the SL(4, R), or the GL(4-R) covering subgroup.
Journal ArticleDOI
General relativistic boson stars
TL;DR: In this article, the authors focus on the possibilities of detecting the various subtypes of (excited) BSs: possible signals include gravitational redshift and (micro-)lensing, emission of gravitational waves, or, in the case of a giant BS, its dark matter contribution to the rotation curves of galactic halos.
Journal ArticleDOI
Boson stars: alternatives to primordial black holes?
TL;DR: In this paper, it was shown that for a very light axion of effective string models, their total gravitational mass will be in the most likely range of ∼0.5M⊙ of MACHOs.
Book ChapterDOI
Rotating Boson Stars
TL;DR: In this paper, the authors concentrate on the fascinating possibility of weakening the uniqueness theorem for rotating configurations and soliton-type collisions of excited boson stars (BSs) in the case of soliton collisions.
Journal ArticleDOI
Boson Stars: Rotation, Formation, and Evolution
TL;DR: In this article, the authors explore the evolution of scalar-tensortheories and show how to detect boson stars by gravitationallensing or gravitational redshift.
