    We present the first event-horizon-scale images and spatiotemporal analysis of Sgr A* taken with the Event Horizon Telescope in 2017 April at a wavelength of 1.3 mm. Imaging of Sgr A* has been conducted through surveys ...

  • 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 ...
