An observational program focused on the high redshift (2< z< 6) Universe has the
opportunity to dramatically improve over upcoming LSS and CMB surveys on measurements …

The cross-correlation of gravitational wave strain with upcoming galaxy surveys probes
theories of gravity in a new way. This method enables testing the theory of gravity by …

We critically examine the state of current constraints on the dark energy (DE) equation of
state (EoS) w. Our study is motivated by the observation that, while broadly consistent with …

While astrophysical and cosmological probes provide a remarkably precise and consistent
picture of the quantity and general properties of dark matter, its fundamental nature remains …

The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB)
experiment sited on Cerro Toco in the Atacama Desert in Chile that promises to provide …

We investigate how much can be learnt about four types of primordial non-Gaussianity
(PNG) from small-scale measurements of the halo field. Using the quijote-png simulations …

Scalar field ϕ CDM models provide an alternative to the standard Λ CDM paradigm, while
being physically better motivated. Dynamical scalar field ϕ CDM models are divided into two …

MegaMapper is a proposed ground-based experiment to measure Inflation parameters and
Dark Energy from galaxy redshifts at 2< z< 5. A 6.5-m Magellan telescope will be coupled …

PUMA is a proposal for an ultra-wideband, low-resolution and transit interferometric radio
telescope operating at $200-1100\,\mathrm {MHz} $. Its design is driven by six science goals …

Advances in experimental techniques make it possible to map the high redshift Universe in
three dimensions at high fidelity in the near future. This will increase the observed volume by …
