Mixing of scalar and tensor metric perturbations
A. D. Dolgov, L. A. Panasenko
Metric perturbations in General Relativity are usually separated into three distinct classes: scalar, vector, and tensor. In many cases these modes are separable, i.e. they satisfy…
Gravitational Baryogenesis: Problems and Possible Resolution
E. Arbuzova, A. Dolgov, K. Dutta +1
The coupling of baryonic current to the derivative of the curvature scalar, , inherent to gravitational baryogenesis (GBG), leads to a fourth order differential equation of moti…
Antimatter in the Milky Way
A. D. Dolgov
Recent astronomical observations indicating a strikingly abundant presence of antimatter in the Galaxy, in particular, of anti-stars are reviewed. Long-time earlier theoretical pre…
X-ray signature of antistars in the Galaxy
A. E. Bondar, S. I. Blinnikov, A. M. Bykov +2
The existence of macroscopic objects from antimatter (antistars) is envisaged in some models of baryogenesis. Searches for antistars has been usually carried out in gamma-rays thro…
Asymmetric baryon capture by primordial black holes and baryon asymmetry of the universe
A. D. Dolgov, N. A. Pozdnyakov
We have refined our previously suggested scenario of generation of the cosmological baryon asymmetry through an asymmetric capture of baryons and antibaryons by primordial block ho…
Coalescing primordial binary black holes with log-normal mass spectrum
Konstantin Postnov, Alexander Dolgov, Nikita Mitichkin +1
Primordial black holes created in the early Universe can constitute a substantial fraction of dark matter and serve as seeds for early galaxy formation. Binary primordial black hol…
