Cosmic antimatter: models and observational bounds
A.D. Dolgov
TL;DR
This paper proposes a model where abundant antimatter objects like anti-stars and anti-clouds exist in the Galaxy, potentially accounting for all dark matter as compact baryonic and antibaryonic objects, with observational implications analyzed.
Contribution
It introduces a novel model allowing for significant antimatter objects in the Galaxy, providing a new perspective on dark matter composition.
Findings
Model predicts abundant antimatter objects in the Galaxy.
Observational signatures of antimatter objects are analyzed.
Dark matter could be entirely composed of compact baryonic and antibaryonic objects.
Abstract
A model which leads to abundant antimatter objects in the Galaxy (anti-clouds, anti-stars, etc) is presented. Observational manifestations are analyzed. In particular, the model allows for all cosmological dark matter to be made out of compact baryonic and antibaryonic objects.
