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…
Receiver design for the REACH global 21-cm signal experiment
Ian L. V. Roque, Nima Razavi-Ghods, Steven H. Carey +35
We detail the the REACH radiometric system designed to enable measurements of the 21-cm neutral hydrogen line. Included is the radiometer architecture and end-to-end system simulat…
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…
Antenna beam characterisation for the global 21cm experiment LEDA and its impact on signal model parameter reconstruction
M. Spinelli, G. Kyriakou, G. Bernardi +4
Cosmic Dawn, the onset of star formation in the early universe, can in principle be studied via the 21cm transition of neutral hydrogen, for which a sky-averaged absorption signal,…
