Measuring the H I mass function below the detection threshold
Jarvis, Matt; Pan, Hengxing; Allison, James (Oxford University Press, 2019-10-30)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 ... -
Measuring the HI mass function below the detection threshold
Pan, Hengxing; Jarvis, Matt J.; Santos, Mario G. (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 ... -
MIGHTEE-H I: the first MeerKAT H I mass function from an untargeted interferometric survey
Jarvis, Matt J; Pan, Hengxing; Ponomareva, Anastasia A; Maddox, Natasha (Oxford University Press, 2023)We present the first measurement of the H I mass function (HIMF) using data from MeerKAT, based on 276 direct detections from the MeerKAT International GigaHertz Tiered Extragalactic Exploration (MIGHTEE) Survey Early ...
