Natural Saturation Of The Sterile Neutrino Dark Matter Resonant Production By a High Lepton Flavor Asymmetry In Primordial Plasma
Dmitry Gorbunov, Dmitry Kalashnikov
Sterile neutrinos remain a well-motivated dark-matter candidate whose cosmological abundance can be enhanced by resonant active--sterile conversion in the presence of a lepton asym…
Thermal false vacuum decay near black holes is aspherical
D. S. Gorbunov, D. G. Levkov, V. E. Maslov
We study decay of a scalar field false vacuum near a (3+1)-dimensional Schwarzschild black hole equilibrated at Hawking temperature with the environment. Our scalar field model has…
False vacuum decay around black holes: calculation from first principles in the (3+1)-dimensional case
Ratmir Gazizov, Dmitry Gorbunov, Dmitry Levkov
In spacetime dimensions, we numerically calculate the suppression exponent of the false vacuum decay probability in the presence of a thermal bath and a black hole.
Domain walls through different cosmologies
I. Dankovsky, D. Gorbunov, S. Ramazanov +1
We study properties of domain walls (DWs) arising in the model with a double well potential assuming different early universe cosmologies: from dust through stiff matter domination…
Fixing IR tail of gravitational waves from domain walls
Ivan Dankovsky, Dmitry Gorbunov
Numerical simulations of gravitational waves (GW) production during violent evolution of matter inhomogeneities in the early Universe yield highly wiggle infrared parts of the spec…
Constraints on the parameters of keV-scale mass annihilating Dark Matter obtained with SRG/ART-XC observations
E. I. Zakharov, V. V. Barinov, R. A. Burenin +2
In this paper we present new constraints on the velocity-independent cross section of keV-scale mass annihilating Dark Matter particles obtained with SRG/ART-XC after 4 full-sky su…
