The nature of the most abundant components of the Universe, dark energy and dark matter, is still to be uncovered. I tackle this subject considering a novel cosmological probe: the neutral hydrogen emitted 21cm radiation, observed with the intensity mapping technique. I analyse competitive and realistic dark energy and dark matter models and show how they produce distinctive and detectable effects on the 21cm signal. Moreover, I provide radio telescope forecasts showing how these models will be… Expand

Cosmology on ultralarge scales with intensity mapping of the neutral hydrogen 21 cm emission: limits on primordial non-Gaussianity.
It is argued that it may be possible to place tight constraints on the non-Gaussianity parameter f(NL), with an error close to σ(f(NL))~1, to place stringent bounds on different models of inflation. Expand

The extent to which precision distance-redshift observations can map out the recent expansion history of the universe, including the acceleration-deceleration transition, and the components and equations of state of the energy density is examined. Expand
Imprints of dark energy on cosmic structure formation – I. Realistic quintessence models and the non‐linear matter power spectrum
Quintessence has been proposed to account for dark energy (DE) in the Universe. This component causes a typical modification of the background cosmic expansion, which, in addition to its clusteringExpand
Cold dark matter: Controversies on small scales
Gravitational lensing and dynamical perturbations of tidal streams in the stellar halo provide evidence for an abundant population of low-mass subhalos in accord with CDM predictions. Expand
Small scale clustering of late forming dark matter
The model largely satises highredshift matter power spectrum constraints from Lyman- forest measurements, while it predicts suppressed abundance of low-mass halos ( 10 9 10 10 h 1 M ) at allExpand
The evolution of large-scale structure in a universe dominated by cold dark matter
The results of numerical simulations of nonlinear gravitational clustering in universes dominated by weakly interacting, 'cold' dark matter are presented. The numerical methods used and the way inExpand
Late forming dark matter in theories of neutrino dark energy
We study the possibility of late forming dark matter, where a scalar field, previously trapped in a metastable state by thermal or finite density effects, goes through a phase transition near the eraExpand
Constraints on dark matter scenarios from measurements of the galaxy luminosity function at high redshifts
We use state-of-the-art measurements of the galaxy luminosity function (LF) at z=6, 7, and 8 to derive constraints on warm dark matter (WDM), late-forming dark matter, and ultralight axion darkExpand
Planck 2015 results - XIII. Cosmological parameters
This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. Our results are inExpand
Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant
We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 " z " 0.62. The luminosity distances of these objects are determined by methods thatExpand
