The Extended GMRT Radio Halo Survey II: Further results and analysis of the full sample
R. Kale, T. Venturi, S. Giacintucci +6
The intra-cluster medium contains cosmic rays and magnetic fields that are manifested through the large scale synchrotron sources, termed as radio halos, relics and mini-halos. The…
The Extended GMRT Radio Halo Survey I: New upper limits on radio halos and mini-halos
R. Kale, T. Venturi, S. Giacintucci +5
A fraction of galaxy clusters host diffuse radio sources called radio halos, radio relics and mini-halos. We present the sample and first results from the Extended GMRT Radio Halo…
Low-frequency radio observations of Seyfert galaxies: A test to the unification scheme
Veeresh Singh, Prajval Shastri, Ishwara-Chandra C. H. +1
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…
153 MHz GMRT follow-up of steep-spectrum diffuse emission in galaxy clusters
G. Macario, T. Venturi, H. T. Intema +7
In this paper 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 clust…
A survey for HI in the distant Universe: the detection of associated 21-cm absorption at z=1.28
S. J. Curran, M. T. Whiting, A. Tanna +3
We have undertaken a survey for HI 21-cm absorption within the host galaxies of z ~ 1.2 - 1.5 radio sources, in the search of the cool neutral gas currently "missing" at z > 1. Thi…
Low frequency follow up of radio halos and relics in the GMRT Radio Halo Cluster Survey
Tiziana Venturi, Simona Giacintucci, Daniele Dallacasa +4
We performed GMRT low frequency observations of the radio halos, relics and new candidates belonging to the GMRT Radio Halo Cluster Sample first observed at 610 MHz. High sensitivi…
