A radio minihalo in the extreme cool-core galaxy cluster RXCJ1504.1-0248
S. Giacintucci, M. Markevitch, G. Brunetti +2
Aims. We report the discovery of a radio minihalo in RXCJ1504.1-0248, a massive galaxy cluster that has an extremely luminous cool core. To date, only 9 radio minihalos are known,…
Radio Halos and the importance of future observations at low frequency
G. Brunetti, R. Cassano
Radio observations discovered large scale non thermal sources in the central Mpc regions of dynamically disturbed galaxy clusters (radio halos). The morphological and spectral prop…
On the connection between giant radio halos and cluster mergers
R. Cassano, S. Ettori, S. Giacintucci +4
The frequently observed association between giant radio halos and merging galaxy clusters has driven present theoretical models of non-thermal emission from galaxy clusters, which…
A decline and fall in the future of Italian Astronomy?
Angelo Antonelli, Vincenzo Antonuccio-Delogu, Andrea Baruffolo +89
On May 27th 2010, the Italian astronomical community learned with concern that the National Institute for Astrophysics (INAF) was going to be suppressed, and that its employees wer…
The very steep spectrum radio halo in Abell 697
Giulia Macario, Tiziana Venturi, Gianfranco Brunetti +5
In this paper we present a detailed study of the giant radio halo in the galaxy cluster Abell 697, with the aim to constrain its origin and connection with the cluster dynamics. We…
On the radio -- X-ray luminosity correlation of radio halos at low radio frequency - Application of the turbulent re-acceleration model
Rossella Cassano
In this paper we show expectations on the radio--X-ray luminosity correlation of radio halos at 120 MHz. According to the "turbulent re-acceleration scenario", low frequency observ…
