The cluster relic source in A521
S. Giacintucci, T. Venturi, S. Bardelli +3
We present high sensitivity radio observations of the merging cluster A521, at a mean redsfhit z=0.247. The observations were carried out with the GMRT at 610 MHz and cover a regio…
Resolving the Shocks in Radio Galaxy Nebulae: HST and Radio Imaging of 3C 171, 3C277.3 and PKS2250-41
Avanti Tilak, Christopher P. O'Dea, Clive Tadhunter +5
We present the results of HST/WFPC2 medium and narrow band imaging and VLA and MERLIN2 radio imaging of three powerful radio galaxies: 3C 171, 3C 277.3, and PKS 2250-41. We obtaine…
Extended emission around GPS radio sources
C. Stanghellini, C. P. O'Dea, D. Dallacasa +4
Extended radio emission detected around a sample of GHz Peaked Spectrum (GPS) radio sources is discussed. Evidence for extended emission which is related to the GPS source is found…
Spectral properties and origin of the radio halo in A3562
S. Giacintucci, T. Venturi, G. Brunetti +6
We present a new detailed multiband study of the merging cluster A3562, in the core of the Shapley Concentration Supercluster. We analyzed new, low frequency radio data performed a…
A Supernova Factory in Mrk 273?
M. Bondi, M-A. Perez-Torres, D. Dallacasa +1
We report on 1.6 and 5.0 GHz observations of the ultraluminous infrared galaxy (ULIRG) Mrk 273, using the European VLBI Network (EVN) and the Multi-Element Radio-Linked Interferome…
Multi-frequency VLBA observations of compact sources from the Peacock & Wall catalogue
A. Rossetti, F. Mantovani, D. Dallacasa +2
VLBA observations are presented for 6 compact radio sources selected from the Peacock & Wall catalogue. From the new morphological and spectral information 2 objects that in the Pe…
EVN observations of eleven GHz-Peaked-Spectrum radio sources at 2.3/8.4GHz
L. Xiang, D. Dallacasa, P. Cassaro +2
We present results of EVN observations of eleven GHz-Peaked-Spectrum (GPS) radio sources at 2.3/8.4 GHz. These sources are from the classical ''bright'' GPS source samples with pea…
