  • The e-MERGE Survey (e-MERLIN Galaxy Evolution Survey) : overview and survey description 
    Muxlow, T.W.B.; Thomson, A.P.; Radcliffe, Jack Frederick; Wrigley, N.H.; Beswick, R.J.; Smail, Ian; McHardy, I.M.; Garrington, S.T.; Ivison, R.J.; Jarvis, M.J.; Prandoni, I.; Bondi, M.; Guidetti, D.; Argo, M.K.; Bacon, David; Best, P.N.; Biggs, A.D.; Chapman, S.C.; Coppin, K.; Chen, H.; Garratt, T.K.; Garrett, M.A.; Ibar, E.; Kneib, Jean-Paul; Knudsen, Kirsten K.; Koopmans, L.V.E.; Morabito, L.K.; Murphy, E.J.; Njeri, A.; Pearson, Chris; Perez-Torres, M.A.; Richards, A.M.S.; Rottgering, H.J.A.; Sargent, M.T.; Serjeant, Stephen; Simpson, C.; Simpson, J.M.; Swinbank, A.M.; Varenius, E.; Venturi, T. (Royal Astronomical Society, 2020-06)
    We present an overview and description of the e-MERGE Survey (e-MERLIN Galaxy Evolution Survey) Data Release 1 (DR1), a large program of high-resolution 1.5-GHz radio observations of the GOODS-N field comprising ∼140 h ...
  • Nowhere to hide : radio-faint AGN in the GOODS-N field : II. Multi-wavelength AGN selection techniques and host galaxy properties 
    Radcliffe, Jack Frederick; Barthel, P.D.; Thomson, A.P.; Garrett, M.A.; Beswick, R.J.; Muxlow, T.W.B. (EDP Sciences, 2021-05)
    CONTEXT : Obtaining a census of active galactic nuclei (AGN) activity across cosmic time is critical to our understanding of galaxy evolution and formation. Many AGN classification techniques are compromised by dust ...
  • The radio emission from active galactic nuclei 
    Radcliffe, Jack Frederick; Barthe, P.D.; Garrett, M.A.; Beswick, R.J.; Thomson, A.P.; Muxlow, T.W.B. (EDP Sciences, 2021-05)
    CONTEXT: For nearly seven decades, astronomers have been studying active galaxies, that is to say, galaxies with actively accreting central supermassive black holes: active galactic nuclei (AGN). A small fraction are ...
  • Revisiting a flux recovery systematic error arising from common deconvolution methods used in aperture-synthesis imaging 
    Radcliffe, Jack Frederick; Beswick, R.J.; Thomson, A.P.; Njeri, A.; Muxlow, T.W.B. (Oxford University Press, 2024-01)
    The point-spread function (PSF) is a fundamental property of any astronomical instrument. In interferometers, differing array configurations combined with their uv coverage, and various weighting schemes can produce an ...
  • Searching for obscured AGN in z ∼ 2 submillimetre galaxies 
    Chen, H.; Garrett, M.A.; Chi, S.; Thomson, A.P.; Barthel, P.D.; Alexander, D.M.; Muxlow, T.W.B.; Beswick, R.J.; Radcliffe, Jack Frederick; Wrigley, N.H.; Guidetti, D.; Bondi, M.; Prandoni, I.; Smail, I.; McHardy, I.; Argo, M.K. (EDP Sciences, 2020-06)
    AIMS: Submillimetre-selected galaxies (SMGs) at high redshift (z ∼ 2) are potential host galaxies of active galactic nuclei (AGN). If the local Universe is a good guide, ∼ 50% of the obscured AGN amongst the SMG population ...
