Field Camera Unit for WSO-UV: Phase A Study Report
I. Pagano, F. Bacciotti, L. Bedin +33
World Space Observatory UltraViolet (WSO-UV) is a multipurpose space observatory, made by a 170 cm aperture telescope, capable of UV high-resolution spectroscopy, long slit low-res…
Blazar Duty-Cycle at gamma-ray Frequecies: Constraints from Extragalactic Background Radiation and Prospects for AGILE and GLAST
Carlotta Pittori, Elisabetta Cavazzuti, Sergio Colafrancesco +1
We take into account the constraints from the observed extragalactic gamma-ray background to estimate the maximum duty cycle allowed for a selected sample of WMAP Blazars, in order…
Blazar surveys with WMAP and Swift
P. Giommi, M. Capalbi, E. Cavazzuti +7
We present the preliminary results from two new surveys of blazars that have direct implications on the GLAST detection of extragalactic sources from two different perspectives: mi…
ROXA J081009.9+384757.0: a erg/s blazar with hard X-ray synchrotron peak or a new type of radio loud AGN?
P. Giommi, E. Massaro, P. Padovani +10
We report the discovery of ROXA J081009.9+384757.0 = SDSS J081009.9+384757.0, a z=3.95 blazar with a highly unusual Spectral Energy Distribution (SED). This object was first notice…
Swift detection of all previously undetected blazars in a micro-wave flux-limited sample of WMAP foreground sources
P. Giommi, M. Capalbi, E. Cavazzuti +19
Almost the totality of the bright foreground sources in the WMAP CMB maps are blazars, a class of sources that show usually also X-ray emission. However, 23 objects in a flux-limit…
Non-thermal Cosmic Backgrounds from Blazars: the contribution to the CMB, X-ray and gamma-ray Backgrounds
P. Giommi, S. Colafrancesco, E. Cavazzuti +2
We present a new assessment of the contribution of Blazars to the extragalactic background radiation across the e.m. spectrum. Our calculations rely on deep Blazar radio counts tha…
