HI intensity mapping with MeerKAT: Calibration pipeline for multi-dish autocorrelation observations
Jingying Wang, Mario G. Santos, Philip Bull +10
While most purpose-built 21cm intensity mapping experiments are close-packed interferometer arrays, general-purpose dish arrays should also be capable of measuring the cosmological…
Measuring ultra-large scale effects in the presence of 21cm intensity mapping foregrounds
José Fonseca, Michele Liguori
\textsc{Hi} intensity mapping will provide maps of the large-scale distribution of neutral hydrogen (\textsc{Hi}) in the universe. These are prime candidates to be used to constrai…
Probing primordial non-Gaussianity with the power spectrum and bispectrum of future 21cm intensity maps
Dionysios Karagiannis, José Fonseca, Roy Maartens +1
After reionisation, the 21cm emission line of neutral hydrogen within galaxies provides a tracer of dark matter. Next-generation intensity mapping surveys, with the SKA and other r…
Constraining the growth rate by combining multiple future surveys
Jan-Albert Viljoen, José Fonseca, Roy Maartens
The growth rate of large-scale structure provides a powerful consistency test of the standard cosmological model and a probe of possible deviations from general relativity. We use…
High-redshift cosmology with oxygen lines from H surveys
José Fonseca, Stefano Camera
A new generation of cosmological experiments will spectroscopically detect the H line from ELGs at optical/near-infrared frequencies. Other emission lines will also be present,…
