Aims. We present the first results of an ongoing project devoted to the search of giant radio halos in galaxy clusters located in the redshift range z=0.2--0.4. One of the main goa…
The VVDS-VLA Deep Field: III. GMRT observations at 610 MHz and the radio spectral index properties of the sub-mJy population
M. Bondi, P. Ciliegi, T. Venturi +12
We present the low frequency (610 MHz) radio source counts of the VVDS-VLA field and investigate the radio spectral index properties of the sub-mJy population. We use new deep (r.m…
The soft X-ray Cluster-AGN spatial cross-correlation function in the ROSAT-NEP survey
N. Cappelluti, H. Boehringer, P. Schuecker +4
X-ray surveys facilitate investigations of the environment of AGNs. Deep Chandra observations revealed that the AGNs source surface density rises near clusters of galaxies. The nat…

Filippo Frontera, Mauro Orlandini, Raffaella Landi +7
We report on an accurate measurement of the CXB in the 15-50 keV range performed with the Phoswich Detection System (PDS) instrument aboard the BeppoSAX satellite. We establish tha…
The water megamaser in the merger system Arp299
A. Tarchi, P. Castangia, C. Henkel +1
We present preliminary results of an interferometric study of the water megamaser in the merger system Arp299. This system is composed of two main sources: IC694 and NGC3690. There…
A NICMOS search for obscured Supernovae in starburst galaxies
G. Cresci, F. Mannucci, M. Della Valle +1
The detection of obscured supernovae (SNe) in near-infrared monitoring campaigns of starburst galaxies has shown that a significant fraction of SNe is missed by optical surveys. Ho…
