    • A flexible method for estimating luminosity functions via Kernel Density Estimation 

      Jarvis, Matt J.; Yuan, Zunli; Wang, Jiancheng (IOP Publishing, 2020)
      We propose a flexible method for estimating luminosity functions (LFs) based on kernel density estimation (KDE), the most popular nonparametric density estimation approach developed in modern statistics, to overcome ...

    • 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 ...
