Web4 apr. 2024 · Unlike GWs produced during inflation, they are generated and remain in the Hubble horizon until now. Clearly, their wavelengths are smaller than the Hubble radius at the time of GW production. Therefore, the peak frequency of this type of stochastic GWs is typically of order more than 10 3 Hz.

WebAt early stages the axion is held up its potential by Hubble friction, and due to an interaction, the dilaton is also held up its potential, and thus acts as dark energy. Eventually, when the Hubble constant falls below the mass of the axion, the axion rolls down its potential and begins to oscillate. iseg professoresWeb19 aug. 2024 · We present a detailed investigation of a sub-dominant oscillating scalar field ('early dark energy', EDE) in the context of resolving the Hubble tension.
