Towards a multi-tracer neutrino mass measurement with line-intensity mapping
Gali Shmueli, Sarah Libanore, Ely D. Kovetz
Accurately determining neutrino masses is a main objective of contemporary cosmology. Since massive neutrinos affect structure formation and evolution, probes of large scale struct…
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…
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_…
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…
Upcoming searches for decaying dark matter with ULTRASAT ultraviolet maps
Sarah Libanore, Ely D. Kovetz
Decaying dark matter (DDM) can be tested via different astrophysical and cosmological probes. In particular, particles in the 9.5 - 30 eV mass range that decay into monochro…
