DESCRIPTION:Speakers: Vivian POULIN ()\nEarly Dark Energy (EDE)\, an addit
 ional component of dark energy active in the decade of redshift before rec
 ombination\, has emerged as one of the most effective models at resolving 
 the Hubble tension. By reducing the size of the `sound horizon’ that cal
 ibrates CMB and BAO observations\, it is able to fit a variety of datasets
  including the variety of high-H0 measurements\, and may shed light upon t
 he yet-unknown nature of dark energy\, and even inflation.  Yet\, it is cl
 ear that EDE cannot be `the end of the story’ at least in its current fo
 rm\, as it brings up a number of theoretical and observational issues. In 
 this talk\, I will review the current status of EDE models\, highlighting 
 both the successes and challenges that EDE is facing\, and draw implicatio
 ns of what we have learned about EDE towards establishing a new ``concorda
 nce cosmology’’.\n\nhttps://indico.unina.it/event/70/contributions/964
