It is generally taken for granted that our Universe is free of antimatter objects and domains. This certitude has recently been challenged by the possible detection of anti-helium nuclei by AMS-02. Should the observation be confirmed, the existence of nearby antistars would make a plausible hypothesis to explain the origin of the antinuclei. In this paper we use the 10-years Fermi Large Area Telescope (LAT) gamma-ray source catalog to set constraints on the abundance of antistars around the Sun…

Anti-stars in the Milky Way and primordial black holes
. Astronomical data of the several recent years which present an evidence in favour of abundant antimatter population in our Galaxy, Milky Way, are analysed. The data include: registration of

Antistars in the Galaxy
Possible existence of antimatter in our Galaxy, in particular of antistars is discussed and the mechanism of their creation is decribed.
X-ray signature of antistars in the Galaxy
The existence of macroscopic objects from antimatter (antistars) is envisaged in some models of baryogenesis. Searches for antistars have been usually carried out in gamma-rays originated from
Ultrahigh-energy Gamma Rays and Gravitational Waves from Primordial Exotic Stellar Bubbles
We put forward a novel class of exotic celestial objects that can be produced through phase transitions occurred in the primordial Universe. These objects appear as bubbles of stellar sizes and can

Observational Tests of Antimatter Cosmologies
In approaching the problem of the amount and astrophysical role of antimatter in the Universe, it is valuable to distinguish between two separate questions. First, must the universe be symmetric.
Where do the AMS-02 antihelium events come from?
We discuss the origin of the anti-helium-3 and -4 events possibly detected by AMS-02. Using up-to-date semi-analytical tools, we show that spallation from primary hydrogen and helium nuclei onto the
Antimatter in the Universe: constraints from gamma-ray astronomy
We review gamma-ray observations that constrain antimatter – both baryonic and leptonic - in the Universe. Antimatter is probed through ordinary matter, with the resulting annihilation gamma-rays

Optical spectroscopic observations of low-energy counterparts of Fermi-LAT γ-ray sources
Context. A significant fraction of all γ-ray sources detected by the Large Area Telescope aboard the Fermi satellite is still lacking a low-energy counterpart. In addition, there is still a large
