    • The Dynamics of Radio Galaxies and Double-Double Radio Galaxies 

      Konar, C.; Jamrozy, M.; Hardcastle, M.J.; Croston, J.H.; Nandi, S.; Saikia, D. J.; Machalski, J. (2011-12)
      Relativistic and magnetized plasma ejected by radio loud AGNs through jets form the diffuse lobes of radio galaxies. The radiating particles (electron/electron-positron) in lobes emit in radio via the synchrotron process ...

(2011)
      EMU is a wide-field radio continuum survey planned for the new Australian Square Kilometre Array Pathfinder (ASKAP) telescope. The primary goal of EMU is to make a deep (rms ~ 10 microJy/beam) radio continuum survey of the ...

    • LeMMINGs – I. The eMERLIN legacy survey of nearby galaxies. 1.5-GHz parsec-scale radio structures and cores 

      Baldi, R. D.; Williams, D.R.A.; McHardy, I.M.; Beswick, R.J.; Argo, M. K.; Dullo, B. T.; Knapen, J. H.; Brinks, Elias; Muxlow, T. W. B.; Aalto, S.; Alberdi, A.; Bendo, G.

A.; Saikia, D. J.; Shankar, F.; Spencer, R. E.; Stevens, I. R.; Uttley, P.; Westcott, J. (2018-05-21)
      We present the first data release of high-resolution (≤0.2 arcsec) 1.5-GHz radio images of 103 nearby galaxies from the Palomar sample, observed with the eMERLIN array, as part of the LeMMINGs survey. This sample includes ...

E.; Stevens, I. R.; Uttley, P.; Brinks, E.; Corbel, S.; Martí-Vidal, I.; Mundell, C. G.; Pahari, M.; Ward, M. J. (2021-12-01)
      What determines the nuclear radio emission in local galaxies? To address this question, we combine optical [O iii] line emission, robust black hole (BH) mass estimates, and high-resolution e-MERLIN 1.5-GHz data, from the ...
