Comparison of Hi and optical redshifts of galaxies - The impact of redshift uncertainties on spectral line stacking
Maddox, Natasha; Hess, Kelley M.; Blyth, S.-L.; Jarvis, Matt (Oxford University Press, 2013)Accurate optical redshifts will be critical for spectral co-adding techniques used to extract detections from below the noise level in ongoing and upcoming surveys for Hi, which will extend our current understanding of ... -
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 ... -
The star formation rates of QSOs
Symeonidis, Myrto; Maddox, Natasha; Jarvis, Matthew J. (Royal Astronomical Society, 2022)We examine the far-IR properties of a sample of 5391 optically selected QSOs in the 0.5 < z < 2.65 redshift range down to log [νLν,2500(erg/s)] > 44.7, using SPIRE data from Herschel-ATLAS. We split the sample in a grid ...
