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 optically selected 1.4-GHz quasar luminosity function below 1 mJy
Malefahlo, Eliab; Santos, Mario G.; Jarvis, Matt J; White, Sarah V.; Zwart, Jonathan T. L. (Oxford University Press, 2020)We present the radio luminosity function (RLF) of optically selected quasars below 1 mJy, constructed by applying a Bayesian-fitting stacking technique to objects well below the nominal radio flux density limit. We test ... -
The performance of photometric reverberation mapping at high redshift and the reliability of damped random walk models
Read, Shaun C; Smith, Daniel James B; Jarvis, Matt J (Oxford University Press, 2020)Accurate methods for reverberation mapping using photometry are highly sought after since they are inherently less resource intensive than spectroscopic techniques. However, the effectiveness of photometric reverberation ... -
Spectral age distribution for radio-loud active galaxies in the XMM-LSS field
Jarvis, Matt J; Whittam, Imogen H; Pinjarkar, Siddhant; Hardcastle, Martin J (Monthly Notices of the Royal Astronomical Society, 2023)Jets of energetic particles, as seen in FR type-I and FR type-II sources, ejected from the centre of radio-loud AGN affect the sources surrounding the intracluster medium/intergalactic medium. Placing constraints on the ...
