Does it matter? A more careful treatment of density fluctuations in 21-cm simulations
Jordan Flitter, Sarah Libanore, Ely D. Kovetz
The cosmological 21-cm signal is sourced from hyperfine transitions in neutral hydrogen atoms. Yet, although the abundance of hydrogen atoms follows the baryon density field, semi-…
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…
Probing Dark Relativistic Species and Their Interactions with Dark Matter through CMB and 21cm surveys
Hugo Plombat, Théo Simon, Jordan Flitter +1
We investigate the sensitivity of the 21cm power spectrum from cosmic dawn and the epoch of reionization to models of free-streaming dark radiation (parameterized through $N_{\rm e…
Constraints on the fuzzy dark matter mass window from high-redshift observables
Hovav Lazare, Jordan Flitter, Ely D. Kovetz
We use a combination of high-redshift observables to extract the strongest constraints to date on the fraction of axion fuzzy dark matter (FDM) in the mass window $10^{-26}\,\mathr…
