Macroscopic cosmic antimatter objects are predicted in baryonasymmetrical Universe in the models of strongly nonhomogeneousbaryosynthesis. We test the hypothesis of the existence of an oldglobular cluster of anti-stars in the galactic halo by evaluating theflux of helium anti-nuclei in galactic cosmic rays. Due to the symme-try of matter and antimatter we assume that the antimatter clusterevolves in a similar way as a matter cluster. The energy density ofantiparticles in galactic cosmic rays…

BSM Cosmology from BSM Physics
Now Standard ΛCDM cosmology is based on physics Beyond the Standard Model (BSM), which in turn needs cosmological probes for its study. This vicious circle of problems can be resolved by methods of
Baryon-Antibaryon Annihilation in the Evolution of Antimatter Domains in Baryon-Asymmetric Universe
Non-trivial baryosynthesis scenarios can lead to the existence of antimatter domains in a baryon-asymmetrical Universe. The consequences of antibaryon-baryon annihilation at the border of antimatter
Multimessenger Probes for New Physics in the Light of A. Sakharov’s Legacy in Cosmoparticle Physics
The modern, standard cosmological scenario, which reflects, to a large extent, the development of A. D. Sakharov’s legacy in cosmoparticle physics, involves inflation, baryosynthesis and dark


Possible Origin of Antimatter Regions in the Baryon Dominated Universe
We discuss the evolution of U(1) symmetric scalar field at the inflation epoch with a pseudo Nambu-Goldstone tilt revealing after the end of exponential expansion of the Universe. The U(1) symmetry
Secondary antinuclei from supernova remnants and background for dark matter searches
We compute the spectra of cosmic-ray (CR) nuclei and antinuclei under a scenario where hadronic interaction processes inside supernova remnants (SNRs) can produce a diffusively-shock-accelerated
Monte Carlo Simulations of Star Clusters - V. The globular cluster M4
We describe Monte Carlo models for the dynamical evolution of the nearby globular cluster M4. The code includes treatments of two-body relaxation, three- and four-body interactions involving
A strong, highly-tilted interstellar magnetic field near the Solar System
Measurements of the deflection of the solar wind plasma flows in the heliosheath to determine the magnetic field strength and orientation in the interstellar medium find that the field strength in the local interstellar medium is 3.7–5.5 μG, which concludes that the Interstellar medium field is turbulent or has a distortion in the solar vicinity.

New studies indicate that star clusters can very well harbour multiple stellar populations, possibly formed through self-enrichment processes from the first-generation stars that evolved through post-main-sequence evolutionary phases.
Modelling Individual Globular Clusters
Abstract Astronomers have constructed models of globular clusters for over 100 years. These models mainly fall into two categories: (i) static models, such as King's model and its variants, and (ii)
Matter and Antimatter in the Universe.
The theoretical situation in regards to the matter-antimatter abundances in the universe is reviewed. The various approaches to the problem are discussed in some detail. (WDM)
