    • Cosmic evolution of star-forming galaxies to z 1.8 in the faint low-frequency radio source population 

      Ocran, E. F.; Taylor, A. R.; Vaccari, M. (Oxford University Press, 2019)
      We study the properties of star-forming galaxies selected at 610 MHz with the GMRT in a survey covering ∼1.86 deg2 down to a noise of ∼7.1 μJy beam−1. These were identified by combining multiple classification diagnostics: ...

    • Deep GMRT 610 MHz observations of the ELAIS N1 field: Catalogue and source counts 

      Taylor, A. R.; Ocran, E. F.; Vaccari, M. (Oxford University Press, 2019)
      This is the first of a series of papers based on sensitive 610 MHz observations of the ELAIS N1 field, using the Giant Metrewave Radio Telescope. We describe the observations, processing and source catalogue extraction ...

    • The evolution of the low-frequency radio AGN population to z 1.5 in the ELAIS N1 field 

      Ocran, E. F.; Taylor, A. R.; Vaccari, M. (Oxford University Press, 2021)
      We study the cosmic evolution of radio sources out to z ≃ 1.5 using a GMRT 610 MHz survey covering ∼1.86 deg2 of the ELAIS N1 field with a minimum/median rms noise 7.1/19.5 μJy beam−1 and an angular resolution of 6 arcsec. ...

    • J1615+5452: a remnant radio galaxy in the ELAIS-N1 field 

      Taylor, A. R.; Randriamanakoto, Z.; Ishwara-Chandra, C. H. (Oxford University Press, 2020)
      We report the discovery of a remnant radio active galactic nucleus (AGN) J1615+5452 in the field of ELAIS-N1. GMRT continuum observations at 150, 325, and 610 MHz combined with archival data from the 1.4 GHz NVSS survey ...

    • The optical polarization of the blazar PKS 2155–304 during an optical flare in 2010 

      Taylor, A. R.; Peceur, N. W.; Kraan-Korteweg, R. C. (Oxford University Press, 2020)
      An analysis is presented of the optical polarimetric and multicolour photometric (BVRJ) behaviour of the blazar PKS 2155–304 during an outburst in 2010. This flare develops over roughly 117 d, with a flux doubling time τ ...

    • A wide-area GMRT 610-MHz survey of ELAIS N1 field 

      Taylor, A. R.; Ishwara-Chandra, C. H.; Green, D. A. (Oxford University Press, 2020)
      In this paper, we present a wide-area 610-MHz survey of the ELAIS N1 field with the GMRT, covering an area of 12.8 deg2 at a resolution of 6 arcsec and with an rms noise of ∼40 μJy beam−1. This is equivalent to ∼20 μJy ...
