We report the most sensitive upper limits to date on the 21 cm epoch of reionization power
spectrum using 94 nights of observing with Phase I of the Hydrogen Epoch of Reionization …

We study the possibility of measuring the optical depth at reionization τ without relying on
large-scale cosmic microwave background (CMB) polarization. Our analysis is driven by the …

The 21-cm signal holds the key to understanding the first structure formation during cosmic
dawn. Theoretical progress over the last decade has focused on simulations of this signal …

Near-future facilities observing the high-redshift universe (2< z< 5) will have an opportunity
to take advantage of" multi-tracer" cosmology by observing multiple tracers of the matter …

This paper simplifies the induced four-dimensional gravitational equations originating from a
five-dimensional bulk within the framework of Nash's embeddings, incorporating them into a …

Massive neutrinos modify the expansion history of the universe and suppress the structure
formation below their free streaming scale. Cosmic microwave background (CMB) …

The Euclid mission will measure cosmological parameters with unprecedented precision. To
distinguish between cosmological models, it is essential to generate realistic mock …
