Lowering the Horizon on Dark Energy: A Late-Time Response to Early Solutions for the Hubble Tension
Tal Adi
We present a model-independent null test of the late-time cosmological response to a reduced sound horizon, as typically required by early-universe solutions to the Hubble tension.…

Early Dark Energy Effects on the 21cm Signal
Tal Adi, Jordan Flitter, Ely D. Kovetz
Early dark energy (EDE) is one of the leading models proposed to resolve the perplexing Hubble tension. Despite extensive scrutiny and testing against various observables, conclusi…

Towards alleviating the and tensions with Early Dark Energy - Dark Matter drag
Théo Simon, Tal Adi, José Luis Bernal +3
Early dark energy, an additional component of dark energy active in the decade of redshift before recombination, has emerged as one of the most effective models at reducing the $H_…
