Searching for supergiant fast X-ray transients with Swift
P. Romano, E. Bozzo, P. Esposito +11
Supergiant fast X-ray transients (SFXTs) are high mass X-ray binaries (HMXBs) hosting a neutron star and an OB supergiant companion. We examine the available Swift data, as well as…
The ultraluminous GRB 110918A
D. D. Frederiks, K. Hurley, D. S. Svinkin +29
GRB 110918A is the brightest long GRB detected by Konus-WIND during its 19 years of continuous observations and the most luminous GRB ever observed since the beginning of the cosmo…
GRB 130427A: a Nearby Ordinary Monster
A. Maselli, A. Melandri, L. Nava +63
Long-duration Gamma-Ray Bursts (GRBs) are an extremely rare outcome of the collapse of massive stars, and are typically found in the distant Universe. Because of its intrinsic lumi…
Supergiant Fast X-ray Transients with Swift: spectroscopic and temporal properties
P. Romano, V. Mangano, L. Ducci +8
Supergiant fast X-ray transients (SFXTs) are a class of high-mass X-ray binaries with possible counterparts in the high energy gamma rays. The Swift SFXT Project has conducted a sy…
Swift observations of two supergiant fast X-ray transient prototypes in outburst
R. Farinelli, P. Romano, V. Mangano +6
We report on the results from observations of the most recent outbursts of XTE J1739-302 and IGR J17544-2619, which are considered to be the prototypes of the supergiant fast X-ray…
The Dark Bursts population in a complete sample of bright Swift Long Gamma-Ray Bursts
A. Melandri, B. Sbarufatti, P. D'Avanzo +11
We study the properties of the population of optically dark events present in a carefully selected complete sample of bright Swift long gamma-ray bursts. The high level of complete…
