K-CLASH: spatially resolving star-forming galaxies in field and cluster environments at z ≈ 0.2–0.6
Jarvis, Matt; Tiley, Alfred L.; Vaughan, Sam P. (Oxford University Press, 2020)We present the KMOS-CLASH (K-CLASH) survey, a K-band Multi-Object Spectrograph (KMOS) survey, of the spatially resolved gas properties and kinematics of 191 (pre-dominantly blue) H α-detected galaxies at 0.2 ≲ z ≲ 0.6 in ... -
K-CLASH: Strangulation and ram pressure stripping in galaxy cluster members at 0.3 < z < 0.6
Jarvis, Matt; Vaughan, Sam; Tiley, Alfred (Oxford University Press, 2020-06-26)Galaxy clusters have long been theorized to quench the star formation of their members. This study uses integral-field unit observations from the K-band MultiObject Spectrograph (KMOS) – Cluster Lensing And Supernova ... -
The lofar two-metre sky survey: Deep fields data release 1. V. Survey description, source classifications, and host galaxy properties
Best, P N; Kondapally, Rohit; Jarvis, Matt (Oxford University Press, 2023)Source classifications, stellar masses, and star-formation rates are presented for ≈80 000 radio sources from the first data release of the Low Frequency Array Two-metre Sky Survey (LoTSS) Deep Fields, which represents the ... -
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 ... -
Mightee-h i: Possible interactions with the galaxy NGC 895
Namumba, Brenda; Román, Javier; Jarvis, Matt (Oxford University Press, 2023)The transformation and evolution of a galaxy is strongly influenced by interactions with its environment. Neutral hydrogen (H i) is an excellent way to trace these interactions. Here, we present H i observations of the ... -
Mightee: Deep 1.4 ghz source counts and the sky temperature contribution of star-forming galaxies and active galactic nuclei
Hale, Catherine; Whittam, Imogen; Jarvis, Matt (Oxford University Press, 2023)We present deep 1.4 GHz source counts from ∼5 deg2 of the continuum Early Science data release of the MeerKAT International Gigahertz Tiered Extragalactic Exploration survey down to S1.4GHz ∼15 μ Jy. Using observations ... -
Mining the Herschel-Astrophysical Terahertz Large Area Survey: submillimetre-selected blazars in equatorial fields
Lopez-Caniego, M.; Gonzalez-Nuevo, J.; Massardi, M.; Jarvis, Matt (Oxford University Press, 2013)The Herschel-Astrophysical Terahertz Large Area Survey (H-ATLAS) provides an unprecedented opportunity to search for blazars at sub-mm wavelengths. We cross-matched the Faint Images of the Radio Sky at Twenty-cm (FIRST) ... -
Overview of Cosmology with the SKA
Maartens, Roy; Abdalla, Filipe B.; Jarvis, Matt; Santos, Mario G. (Proceedings of Science, 2014)The new frontier of cosmology will be led by three-dimensional surveys of the large-scale structure of the Universe. Based on its all-sky surveys and redshift depth, the SKA is destined to revolutionize cosmology, in ... -
The preferentially magnified active nucleus in IRAS F10214+4724 - III. VLBI observations of the radio core
Deane, Roger P.; Rawlings, S.; Jarvis, Matt; Garrett, M. A.; Heywood, Ian; Klöckner, H. R.; Marshall, P. J.; McKean, J. P. (Oxford University Press, 2013)We report 1.7GHz very long baseline interferometry (VLBI) observations of IRAS F10214+4724, a lensed z = 2.3 obscured quasar with prodigious star formation. We detect what we argue to be the obscured active nucleus with ... -
Radio-loud active calactic nucleus: is there a link between luminosity and cluster environment?
Ineson, J.; Croston, J. H.; Jarvis, Matt; Hardcastle, M.J.; Evans, D. A.; Kraft, R. P. (American Physical Society, 2013)We present here the first results from the Chandra ERA (Environments of Radio-loud AGN) Large Project, characterizing the cluster environments of a sample of 26 radio-loud active galactic nuclei (AGNs) at z ∼ 0.5 that ... -
Sample variance, source clustering and their influence on the counts of faint radio sources
Heywood, Ian; Jarvis, Matt; Condon, James J. (Oxford University Press, 2013)The shape of the curves defined by the counts of radio sources per unit area as a function of their flux density was one of the earliest cosmological probes. Radio source counts continue to be an area of astrophysical ... -
The star-formation history of mass-selected galaxies from the VIDEO survey
Zwart, Jonathan T.L.; Jarvis, Matt; Deane, Roger P.; Bonfield, David G.; Knowles, Kenda; Madhanpall, Nikhita; Rahmani, Hadi; Smith, Daniel J.B. (Oxford University Press, 2014)We measure star formation rates (SFRs) and specific SFRs (SSFRs) of Ks-selected galaxies from the VISTA Deep Extragalactic Observations survey by stacking 1.4 GHz Very Large Array data. We split the sample, which spans 0 ... -
Using sparse gaussian processes for predicting robust inertial confinement fusion implosion yields
Jarvis, Matt; Hatfield, Peter; Rose, Steven (arXiv, 2019)Here we present the application of an advanced Sparse Gaussian Process based machine learning algorithm to the challenge of predicting the yields of inertial confinement fusion (ICF) experiments. The algorithm is used ... -
