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.…
Discovery of 59ms Pulsations from 1RXS J141256.0+792204 (Calvera)
S. Zane, F. Haberl, G. L. Israel +10
We report on a multi-wavelength study of the compact object candidate 1RXS J141256.0+792204 (Calvera). Calvera was observed in the X-rays with XMM/EPIC twice for a total exposure t…
The longest observation of a low intensity state from a Supergiant Fast X-ray Transient: Suzaku observes IGRJ08408-4503
L. Sidoli, P. Esposito, L. Ducci
We report here on the longest deep X-ray observation of a SFXT outside outburst, with an average luminosity level of 1E33 erg/s (assuming 3 kpc distance). This observation was 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…
Supergiant fast X-ray transients: the Swift monitoring program
P. Romano, L. Sidoli, G. Cusumano +10
For the first time, Swift is giving us the opportunity to study supergiant fast X-ray transients (SFXTs) throughout all phases of their life: outbursts, intermediate level, and qui…
An ultra-massive fast-spinning white dwarf in a peculiar binary system
S. Mereghetti, A. Tiengo, P. Esposito +3
White dwarfs typically have masses in a narrow range centered at about 0.6 solar masses (Msun). Only a few ultra-massive white dwarfs (M>1.2 Msun) are known. Those in binary system…
