The Hubble tension might be resolved by injecting a new energy component, called Early Dark Energy (EDE), prior to recombination. An Anti-de Sitter (AdS) phase around recombination can make the injected energy decay faster, which thus allows a higher EDE fraction (so larger H0) while prevents degrading the CMB fit. In this work, we test the AdS-EDE model with CMB and Large-Scale Structure (LSS) data. Our CMB dataset consists of low-` part of Planck TT spectrum and SPTpol polarization and…

The difference from 4 to 6 σ in the Hubble constant (H0) between the values observed with the local (Cepheids and Supernovae Ia, SNe Ia) and the high-z probes (Cosmic Microwave Background obtained by
A new perspective on cosmology through Supernovae Ia and Gamma Ray Bursts
The actual knowledge of the structure and future evolution of our universe is based on the use of cosmological models, which can be tested through the so-called ’probes’, namely astrophysical
Do cosmological observations allow a negative $\Lambda$?
In view of the recent measurement of H0 from HST and SH0ES team, we explore the possibility of existence of a negative cosmological constant in the Universe. In this regard, we consider quintessence

Dark energy at early times and ACT data: A larger Hubble constant without late-time priors
Recent observations using the Atacama Cosmology Telescope (ACT) have provided ground-based cosmic microwave background (CMB) maps with higher angular resolution than the Planck satellite. These have
Early Dark Energy can Resolve the Hubble Tension.
TLDR
This work considers two physical models for this early dark energy EDE, one involving an oscillating scalar field and another a slowly rolling field, and performs a detailed calculation of the evolution of perturbations in these models.
