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 …

We construct a model of quintessential inflation in Palatini R 2 gravity employing a scalar
field with a simple exponential potential and coupled to gravity with a running non-minimal …

We develop a systematic framework to compute the primordial power spectrum up to next-to-
next-to-next to leading order (N3LO) in the Hubble-flow parameters for a large class of …

We present detailed forecasts for the constraints on the characteristics of primordial
magnetic fields (PMFs) generated prior to recombination that will be obtained with the …

Using the measurements of tidal deformation in the binary neutron star (BNS) coalescences
can obtain the information of redshifts of gravitational wave (GW) sources, and thus actually …

Cosmic voids are a powerful probe of cosmology and are one of the core observables of
upcoming galaxy surveys. The cross-correlations between voids and other large-scale …

The H 0 tension that the standard Λ CDM model is suffering from can be resolved with
prerecombination early dark energy. We present the first constraint on the tensor-to-scalar …

Conventionally, in galaxy surveys, cosmological constraints on the growth and expansion
history of the Universe have been obtained from the measurements of redshift-space …

In this review, we outline the expected tests of gravity that will be achieved at cosmological
scales in the upcoming decades. We focus mainly on constraints on phenomenologically …

The fluctuations in the dark matter-baryon relative velocity field are imprinted as acoustic
oscillations in the 21-cm power spectrum during cosmic dawn (CD). These velocity acoustic …
