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…
The foreground transfer function for HI intensity mapping signal reconstruction: MeerKLASS and precision cosmology applications
Steven Cunnington, Laura Wolz, Philip Bull +8
Blind cleaning methods are currently the preferred strategy for handling foreground contamination in single-dish HI intensity mapping surveys. Despite the increasing sophistication…
The REACH radiometer for detecting the 21-cm hydrogen signal from redshift 7.5 to 28
E. de Lera Acedo, D. I. L. de Villiers, N. Razavi-Ghods +31
Observations of the 21-cm line from primordial hydrogen promise to be one of the best tools to study the early epochs of the Universe: the Dark Ages, the Cosmic Dawn, and the subse…
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…
HI intensity mapping with MeerKAT: power spectrum detection in cross-correlation with WiggleZ galaxies
Steven Cunnington, Yichao Li, Mario G. Santos +13
We present a detection of correlated clustering between MeerKAT radio intensity maps and galaxies from the WiggleZ Dark Energy Survey. We find a detection of the cross-corre…
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…
