Suzaku observes weak flares from IGR J17391-3021 representing a common low-activity state in this SFXT
A. Bodaghee, J. A. Tomsick, J. Rodriguez +4
We present an analysis of a 37-ks observation of the supergiant fast X-ray transient (SFXT) IGR J17391-3021 (=XTE J1739-302) gathered with Suzaku. The source evolved from quiescenc…
Confirmation of the Supergiant Fast X-ray Transient nature of AX J1841.0-0536 from Swift outburst observations
P. Romano, V. Mangano, G. Cusumano +8

The exposure of the hybrid detector of the Pierre Auger Observatory
The Pierre Auger Collaboration
The Pierre Auger Observatory is a detector for ultra-high energy cosmic rays. It consists of a surface array to measure secondary particles at ground level and a fluorescence detec…
Suzaku and SWIFT-BAT observations of a newly discovered Compton-thick AGN
P. Severgnini, A. Caccianiga, R. Della Ceca +4
Obscured AGN are fundamental to understand the history of Super Massive Black Hole growth and their influence on galaxy formation. However, the Compton-thick AGN (NH>1e24 cm^-2) po…

M. Ajello, P. Rebusco, N. Cappelluti +4
We report on the discovery of 10 additional galaxy clusters detected in the ongoing Swift/BAT all-sky survey. Among the newly BAT-discovered clusters there are: Bullet, Abell 85, N…
The Palermo Swift-BAT hard X-ray catalogue III. Results after 54 months of sky survey
G. Cusumano, V. La Parola, A. Segreto +10
We present the Second Palermo Swift-BAT hard X-ray catalogue obtained by analysing data acquired in the first 54 months of the Swift mission. Using our software dedicated to the an…
Two years of monitoring Supergiant Fast X-ray Transients with Swift
P. Romano, V. La Parola, S. Vercellone +10
We present two years of intense Swift monitoring of three SFXTs, IGR J16479-4514, XTE J1739-302, and IGR J17544-2619 (since October 2007). Out-of-outburst intensity-based X-ray (0.…
Design Concepts for the Cherenkov Telescope Array
The CTA Consortium
Ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes. Ground-based gamma-ray…
The broad-band X-ray spectrum of the Seyfert 1 galaxy, MCG+8-11-11
Stefano Bianchi, Ilaria De Angelis, Giorgio Matt +5
We present a long (100 ks) Suzaku observation of one of the X-ray brightest AGN, MCG+8-11-11. These data were complemented with the 54-month Swift BAT spectrum, allowing us to perf…
The 2008 October Swift detection of X-ray bursts/outburst from the transient SGR-like AXP 1E 1547.0-5408
G. L. Israel, P. Esposito, N. Rea +17
We report on the detailed study of the 2008 October outburst from the anomalous X-ray pulsar (AXP) 1E 1547.0-5408 discovered through the Swift/Burst Alert Telescope (BAT) detection…
The Swift-BAT hard X-ray sky monitoring unveils the orbital period of the HMXB IGR J16493-4348
G. Cusumano, V. La Parola, P. Romano +3
IGR J16493-4348 is a supergiant high mass X-ray binary discovered by INTEGRAL in 2004. The source is detected at a significance level of standard deviations in the Swift-B…
Detection of an orbital period in the supergiant high mass X-ray binary IGR J164654507 with Swift-BAT
V. La Parola, G. Cusumano, P. Romano +3
We analysed the IGR J16465-4507 Burst Alert Teelescope survey data collected during the first 54 months of the Swift mission. The source is in a crowded field and it is revealed th…
Discovery of a new Soft Gamma Repeater, SGR J1833-0832
E. Gogus, G. Cusumano, A. J. Levan +20
On 2010 March 19, the Swift/Burst Alert Telescope triggered on a short burst with temporal and spectral characteristics similar to those of Soft Gamma Repeater (SGR) bursts. The so…
The Swift Burst Analyser I: BAT and XRT spectral and flux evolution of Gamma Ray Bursts
P. A. Evans, R. Willingale, J. P. Osborne +9
Context: Gamma Ray Burst models predict the broadband spectral evolution and the temporal evolution of the energy flux. In contrast, standard data analysis tools and data repositor…
Unveiling the origin of X-ray flares in Gamma-Ray Bursts
G. Chincarini, J. Mao, R. Margutti +10
We present an updated catalog of 113 X-ray flares detected by Swift in the ~33% of the X-ray afterglows of Gamma-Ray Bursts (GRB). 43 flares have a measured redshift. For the first…
