    A young, dusty, compact radio source within a Lyα halo by Barrio, F, Jarvis, M, Rawlings, S, Bauer, A, Croft, S, Hill, G, Manchado, A, McLure, R, Smith, D, Targett, T

    Published 2008
    “…The radio spectral energy distribution implies that the radio jets were triggered < 10^4 years prior to the time at which the object is observed, suggesting that the jet triggering of the active galactic nucleus is recent. The loosely biconical structure of the emission-line halo suggests that it is ionised by photons emitted by the central quasar nucleus and that the central nucleus is obscured by a dusty torus with Av 3.0. …”

    LOFAR/H-ATLAS: the low-frequency radio luminosity–star formation rate relation by Gürkan, G, Hardcastle, M, Smith, D, Best, P, Bourne, N, Calistro-Rivera, G, Heald, G, Jarvis, M, Prandoni, I, Röttgering, H, Sabater, J, Shimwell, T, Tasse, C, Williams, W

    Published 2018
    “…Objects that were not classified as SFGs have higher 150-MHz radio luminosity than would be expected given their SFR, implying an important role for low-level active galactic nucleus activity.…”

    The Stripe 82 1–2 GHz Very Large Array Snapshot Survey: host galaxy properties and accretion rates of radio galaxies by Whittam, I, Prescott, M, McAlpine, K, Jarvis, M, Heywood, I

    Published 2018
    “…We find that 84 per cent of our sample releases more than 10 per cent of their accretion power in their jets, showing that mechanical active galactic nucleus (AGN) feedback is significantly underestimated in many hydrodynamical simulations. …”

    Physical conditions of the interstellar medium of high-redshift, strongly lensed submillimetre galaxies from the Herschel-ATLAS by Valtchanov, I, Virdee, J, Ivison, R, Swinyard, B, van der Werf, P, Rigopoulou, D, da Cunha, E, Lupu, R, Benford, D, Riechers, D, Smail, I, Jarvis, M, Pearson, C, Gomez, H, Hopwood, R, Altieri, B, Birkinshaw, M, Coia, D, Conversi, L, Cooray, A, De Zotti, G, Dunne, L, Frayer, D, Leeuw, L, Marston, A

    Published 2011
    “…The radio observations indicate that SDP.81 deviates significantly from the local far-infrared/radio (FIR/radio) correlation, which hints that some fraction of the radio emission is coming from an active galactic nucleus (AGN). The constraints on the source size from millimetre-wave observations put a very conservative upper limit of the possible AGN contribution to less than 33 per cent. …”
