Deep GMRT 150 MHz observations of the DEEP2 fields: Searching for High Red-shift Radio Galaxies Revisited
Susanta Kumar Bisoi, C. H. Ishwara-Chandra, S. K. Sirothia +1
High red-shift radio galaxies are best searched at low radio frequencies, due to its steep radio spectra. Here we present preliminary results from our programme to search for high…
GMRT 333 MHz observations of 6 nearby normal galaxies
Aritra Basu, Dipanjan Mitra, Yogesh Wadadekar +1
We report Giant Meterwave Radio Telescope (GMRT) continuum observations of six nearby normal galaxies at 333 MHz. The galaxies are observed with angular resolutions better than ~20…
Discovery of the first giant double radio relic in a galaxy cluster found in the PLANCK Sunyaev-Zel'dovich cluster survey: PLCK G287.0+32.9
Joydeep Bagchi, S. K. Sirothia, Norbert Werner +6
We report the discovery of large scale diffuse non-thermal radio emission in PLCK G287.0+32.9, an exceptionally hot (T ~ 13 keV), massive and luminous galaxy cluster, strongly dete…
A combined low-radio frequency/X-ray study of galaxy groups I. Giant Metrewave Radio Telescope observations at 235 MHz and 610 MHz
Simona Giacintucci, Ewan O'Sullivan, Jan Vrtilek +12
We present new Giant Metrewave Radio Telescope observations at 235 MHz and 610 MHz of 18 X-ray bright galaxy groups. These observations are part of an extended project, presented h…
A radio study of the double-double radio galaxy 3C293
S. A. Joshi, S. Nandi, D. J. Saikia +2
We present radio continuum observations at frequencies ranging from 150 to 5000 MHz of the misaligned double-double radio galaxy, DDRG, 3C293 (J1352+3126) using the Giant Met…
GMRT 150 MHz follow up of diffuse steep spectrum radio emission in galaxy clusters
G. Macario, T. Venturi, D. Dallacasa +5
It has been recently found that a few galaxy clusters host diffuse radio halo emission with very steep synchrotron spectra ( > 1.6), which may be classified as Ultra Steep Spect…
