Mildly obscured active galaxies and the cosmic X-ray background
Valentino Esposito, Roland Walter
The diffuse cosmic X-ray background (CXB) is the sum of the emission of discrete sources, mostly massive black-holes accreting matter in active galactic nuclei (AGN). The CXB spect…

The high-energy spectrum of 3C 273
Valentino Esposito, Roland Walter, Pierre Jean +1
The high energy spectral shape of 3C 273 is usually understood in terms of Inverse-Compton emission in a relativistic leptonic jet. This model predicts variability patterns and del…
