Conversion of high frequency relic gravitational waves into photons in cosmological magnetic field
This work continues the research presented in the article [1], where we
estimate the Gertsenshtein effect's influence on the long-wavelength part of
relic gravitational wave spectrum. Here, the differential equation system for
the Gertsenshtein effect in Friedman-LeMaitre-Robertson-Walker universe,
derived in [1], is simplified for gravitational waves in the under-horizon
regime during radiation dominance epoch. Then, the obtained system is solved
analytically. As a result of the solution analysis a conclusion was made about
a significant increase of relic GWs with the frequencies $ k\gtrsim 10^{-11}$
Hz for magnetic field strength about 1 nGs. In addition, at the end of the
article model dependency of the result is discussed
