Beyond ΛCDM with the SKA Observatory -- I: Probing Gravity on Cosmological Scales
S. Camera, C. Addis, S. L. Guedezounme +26
General relativity (GR) is currently the best description of the gravitational interaction at our disposal and is one of the foundations of the concordance cosmological model. For…
Cosmology with HI Intensity Mapping
Laura Wolz, Gabriele Autieri, José Luis Bernal +18
The redshifted spectral emission from neutral hydrogen (HI) at rest wavelength 21 cm can be used as a tracer of large-scale structure and its evolution. Within the HI intensity map…
The impact of evolving dark energy on the Weyl potential measured from the Dark Energy Survey Year 3 data
Benedetta Rosatello, Gen Ye, Maria Berti +3
Measurements from the Dark Energy Survey (DES) Year 3 data have shown that the Weyl potential -- the sum of the spatial and temporal distortions of the geometry -- evolves more slo…
Weighing neutrinos with 21cm Intensity Mapping at the SKAO
Gabriele Autieri, Maria Berti, Marta Spinelli +2
We explore the constraining power of future 21cm intensity mapping (IM) observations at the SKAO, focusing primarily on the sum of neutrino masses, . We forecast observations…
Reconstructing the dark energy density in light of DESI BAO observations
Maria Berti, Emilio Bellini, Camille Bonvin +3
In light of the evidence for dynamical dark energy (DE) found from the most recent Dark Energy Spectroscopic Instrument (DESI) baryon acoustic oscillation (BAO) measurements, we pe…
21cm Intensity Mapping cross-correlation with galaxy surveys: current and forecasted cosmological parameters estimation for the SKAO
Maria Berti, Marta Spinelli, Matteo Viel
We present a comprehensive set of forecasts for the cross-correlation signal between 21cm intensity mapping and galaxy redshift surveys. We focus on the data sets that will be prov…
Cosmological Probes of Structure Growth and Tests of Gravity
Jiamin Hou, Julian Bautista, Maria Berti +4
The current standard cosmological model is constructed within the framework of general relativity with a cosmological constant , which is often associated with dark energy, and…
Testing gravity with gravitational waves electromagnetic probes cross-correlations
Giulio Scelfo, Maria Berti, Alessandra Silvestri +1
In a General Relativistic framework, Gravitational Waves (GW) and Electromagnetic (EM) waves are expected to respond in the same way to the effects of matter perturbations between…
Multipole expansion for 21cm Intensity Mapping power spectrum: forecasted cosmological parameters estimation for the SKA Observatory
Maria Berti, Marta Spinelli, Matteo Viel
The measurement of the large scale distribution of neutral hydrogen in the late Universe, obtained with radio telescopes through the hydrogen 21cm line emission, has the potential…
Constraining beyond CDM models with 21cm intensity mapping forecast observations combined with latest CMB data
Maria Berti, Marta Spinelli, Balakrishna S. Haridasu +2
We explore constraints on dark energy and modified gravity with forecast 21cm intensity mapping measurements using the Effective Field Theory approach. We construct a realistic moc…
