The sub-mJy radio sky in the Extended Chandra Deep Field South: source population
M. Bonzini, P. Padovani, V. Mainieri +5
The sub-mJy radio population is a mixture of active systems, that is star forming galaxies (SFGs) and active galactic nuclei (AGNs). We study a sample of 883 radio sources detected…
The VLA 1.4GHz Survey of the Extended Chandra Deep Field South: Second Data Release
N. A. Miller, M. Bonzini, E. B. Fomalont +6
Deep radio observations at 1.4GHz for the Extended Chandra Deep Field South were performed in June through September of 2007 and presented in a first data release (Miller et al. 20…
Spectrum of the unresolved cosmic X ray background: what is unresolved 50 years after its discovery
A. Moretti, S. Vattakunnel, P. Tozzi +5
We study the spectral properties of the unresolved cosmic X-ray background (CXRB) in the 1.5-7.0 keV energy band with the aim of providing an observational constraint on the statis…
The sub-mJy radio population of the E-CDFS: optical and infrared counterpart identification
M. Bonzini, V. Mainieri, P. Padovani +9
We study a sample of 883 sources detected in a deep Very Large Array survey at 1.4 GHz in the Extended Chandra Deep Field South. The paper focuses on the identification of their op…
The Radio - X-ray relation as a star formation indicator: Results from the VLA--E-CDFS Survey
S. Vattakunnel, P. Tozzi, F. Matteucci +10
In order to trace the instantaneous star formation rate at high redshift, and hence help understanding the relation between the different emission mechanisms related to star format…
Accretion and nuclear activity in Virgo early-type galaxies
Shaji Vattakunnel, Edoardo Trussoni, Alessandro Capetti +1
We use Chandra observations to estimate the accretion rate of hot gas onto the central supermassive black hole in four giant (of stellar mass 10E11 - 10E12 solar masses) early-type…
