Figure 1From: Stochastic backgrounds of relic gravitons: a theoretical appraisalA schematic view of the frequency range of the relic graviton spectrum (plot at the left) and of the electromagnetic spectrum (plot at the right). In both plots the common logarithms of the (comoving) frequency and of the (comoving) wavelengths are reported, respectively, on the horizontal and on the vertical axis.Back to article page
