AGILE and Swift simultaneous observations of the blazar S50716+714 during the bright flare of October 2007
P. Giommi, S. Colafrancesco, S. Cutini +15
We present the results of a series of optical, UV, X-ray and gamma-ray observations of the BL Lac object S50716+714 carried out by the Swift and AGILE satellites in late 2007 when…
A Null Test of the Metric Nature of the Cosmic Acceleration
A. Buzzi, C. Marinoni, S. Colafrancesco
We discuss the testable predictions of a phenomenological model in which the accelerated expansion of the universe is the result of the action of a non-gravitational force field, r…
SZ effect from radio-galaxy lobes: astrophysical and cosmological relevance
S. Colafrancesco
We derive the SZ effect arising in radio-galaxy lobes that are filled with high-energy, non-thermal electrons. We provide here quantitative estimates for SZ effect expected from th…
Warming rays in cluster cool cores
S. Colafrancesco, P. Marchegiani
We present a model of cosmic ray heating of clusters' cores that reproduces the observed temperature distribution in clusters by using an energy balance condition in which the emit…
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…
Direct probes of Dark Matter in the cluster 1ES0657-556 through microwave observations
S. Colafrancesco, P. de Bernardis, S. Masi +2
The cluster 1ES0657-556 is an ideal astrophysical laboratory to study the distribution and the nature of Dark Matter because this last component is spatially separated from the int…
