Measuring the HI mass function below the detection threshold
(Royal Astronomical Society, 2020)
We present a Bayesian stacking technique to directly measure the H I mass function (HIMF) and its evolution with redshift using galaxies formally below the nominal detection threshold. We generate galaxy samples over several ...
H I intensity mapping with MeerKAT: Power spectrum detection in cross-correlation with WiggleZ galaxies
(Oxford University Press, 2023)
We present a detection of correlated clustering between MeerKAT radio intensity maps and galaxies from the WiggleZ Dark Energy Survey. We find a 7.7σ detection of the cross-correlation power spectrum, the amplitude of which ...
