  • Low-frequency radio observations of Seyfert galaxies: A test of the unification scheme 
    Singh, V.; Shastri, P.; Ishwara-Chandra, C. H.; ATHREYA, RAMANA (EDP Sciences, 2013-06)
    Aims. We present low-frequency radio imaging and spectral properties of a well-defined sample of Seyfert galaxies using GMRT 240/610 MHz dual frequency observations. Radio spectra of Seyfert galaxies over 240 MHz to 5.0 ...
  • J021659-044920: a relic giant radio galaxy at z similar to 1.3 
    TAMHANE, PRATHAMESH; Wadadekar, Y.; Basu, A.; Singh, V.; Ishwara-Chandra, C. H.; Beelen, A.; Sirothia, S. (Oxford University Press, 2015-11)
    We report the discovery of a relic Giant Radio Galaxy (GRG) J021659-044920 at redshift z ∼ 1.3 that exhibits large-scale extended, nearly co-spatial, radio and X-ray emission from radio lobes, but no detection of Active ...
