Constraints on millicharged particles from Planck
A. D. Dolgov, S. L. Dubovsky, G. I. Rubtsov +1
We revisit cosmic microwave background (CMB) constraints on the abundance of millicharged particles based on the Planck data. The stringent limit Omega_{mcp}h^2 < 0.001 (95% CL) ma…
The Phase Transition to Eternal Inflation
Paolo Creminelli, Sergei Dubovsky, Alberto Nicolis +2
For slow-roll inflation we study the phase transition to the eternal regime. Starting from a finite inflationary volume, we consider the volume of the universe at reheating as orde…
Narrowing the window for millicharged particles by CMB anisotropy
S. L. Dubovsky, D. S. Gorbunov, G. I. Rubtsov
We calculate the cosmic microwave background (CMB) anisotropy spectrum in models with millicharged particles of electric charge q\sim 10^{-6}-10^{-1} in units of electron charge. W…
Statistics of clustering of ultra-high energy cosmic rays and the number of their sources
S. L. Dubovsky, P. G. Tinyakov, I. I. Tkachev
Observation of clustering of ultra-high energy cosmic rays (UHECR) suggests that they are emitted by compact sources. Assuming small deflection of UHECR during the propagation, the…
