Abstract: Early dark energy (EDE) models have attracted attention in the context of the recent problem of the Hubble tension. Here we extend these models by taking into account the new density fluctuations generated by the… read more here.

Abstract: Current cosmological data exhibit a tension between inferences of the Hubble constant, $H_0$, derived from early and late-universe measurements. One proposed solution is to introduce a new component in the early universe, which initially acts… read more here.

Abstract: Gravitational waves (GWs) search technologies [1ā5] have strong ongoing research interest. Implications from these developments focus not only on discovering new astrophysical objects [6, 7], but also probing gravitation physics [8ā13] and non-standard cosmologies [14ā21];… read more here.

Abstract: Early dark energy (EDE) that behaves like a cosmological constant at early times (redshifts zā³3000) and then dilutes away like radiation or faster at later times can solve the Hubble tension. In these models, the… read more here.
