153 MHz GMRT follow-up of steep-spectrum diffuse emission in galaxy clusters

Macario, G.; Venturi, T.; Intema, H. T.; Dallacasa, D.; Brunetti, G.; Cassano, R.; Giacintucci, S.; Ferrari, C.; Ishwara-Chandra, C. H.; ATHREYA, RAMANA (EDP Sciences, 2013-03)

Aims. We present new high-sensitivity 153 MHz Giant Meterwave Radio Telescope follow-up observations of the diffuse steep-spectrum cluster radio sources in the galaxy clusters Abell 521, Abell 697, and Abell 1682. Abell 521 ...
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 ...
