Domain walls through different cosmologies
I. Dankovsky, D. Gorbunov, S. Ramazanov +1
The paper uses lattice simulations to study how domain wall networks evolve under various early‑universe expansion histories, showing that the particle horizon largely determines w…
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…
Search for a photon peak from keV-scale dark matter annihilation with NuSTAR: Constraints on after 11 years of observations
E. I. Zakharov, V. V. Barinov, D. S. Gorbunov +2
We report new constraints on the velocity-independent annihilation cross section of keV-scale dark matter particles based on 11 years of observations with the…
Cosmic domain walls on a lattice: illusive effects of initial conditions
I. Dankovsky, S. Ramazanov, E. Babichev +2
Evolution of cosmic domain walls (DWs) settles to the scaling solution, which is often assumed to be independent of initial conditions. However, lattice simulations performed in th…
Biased domain walls: faster annihilation, weaker gravitational waves
E. Babichev, I. Dankovsky, D. Gorbunov +2
We study the evolution of domain wall networks and their phenomenological implications in a model of a real scalar , where a -symmetry is slightly broken by a potential bi…
Numerical analysis of melting domain walls and their gravitational waves
I. Dankovsky, S. Ramazanov, E. Babichev +2
We study domain walls (DWs) arising in field theories where -symmetry is spontaneously broken by a scalar expectation value decreasing proportionally to the Universe temperatu…
