The invisible low-frequency gravitons and the audio band

Massimo Giovannini

The low-frequency gravitons correspond to typical wavelengths that left the Hubble radius during the early inflationary stages of expansion and reentered after matter radiation equ…

Relic gravitons and high-frequency detectors

Massimo Giovannini

Cosmic gravitons are expected in the MHz-GHz regions that are currently unreachable by the operating wide-band interferometers and where various classes of electromechanical detect…

The hypermagnetic power spectra and the phases of Sakharov oscillations

Massimo Giovannini

If the gauge fields are amplified from the inflationary vacuum, the quantum mechanical initial data correspond to travelling waves that turn asymptotically into standing waves whos…

The scaling of primordial gauge fields

Massimo Giovannini

The large-scale magnetic fields arising from the quantum mechanical fluctuations of the hypercharge are investigated when the evolution of the gauge coupling is combined with a suf…

Inflation, space-borne interferometers and the expansion history of the Universe

Massimo Giovannini

According to the common wisdom, between a fraction of the mHz and few Hz the spectral energy density of the inflationary gravitons can be safely disregarded even assuming the most…

Flat spectra of cosmic gravitons in the nHz and audio bands

Massimo Giovannini

The spectra of the relic gravitons are customarily normalized in the low-frequency domain where the signal of the concordance paradigm is expected to peak and this is why their con…
