Long-term soft X-ray characterization of Supergiant Fast X-ray Transients: the cumulative luminosity distributions
E. Bozzo, P. Romano, L. Ducci +2
We constructed the cumulative luminosity distributions of most supergiant fast X-ray transients (SFXTs) and the classical supergiant X-ray binary (SgXB) IGR J18027-2016 by taking a…
Supergiant fast X-ray transients as an under-luminous class of supergiant X-ray binaries
E. Bozzo, P. Romano, L. Ducci +2
The usage of cumulative luminosity distributions, constructed thanks to the long-term observations available through wide field hard X-ray imagers, has been recently exploited to s…
Constraining duty cycles through a Bayesian technique
P. Romano, C. Guidorzi, A. Segreto +2
The duty cycle (DC) of astrophysical sources is generally defined as the fraction of time during which the sources are active. However, DCs are generally not provided with statisti…
Expected number of supergiant fast X-ray transients in the Milky Way
L. Ducci, V. Doroshenko, P. Romano +2
In the past fifteen years a new generation of X-ray satellites led to the discovery of a subclass of high-mass X-ray binaries (HMXBs) with supergiant companions and a peculiar tran…
Soft X-ray characterisation of the long term properties of Supergiant Fast X-ray Transients
P. Romano, L. Ducci, V. Mangano +3
We perform the first high-sensitivity soft X-ray long-term monitoring with Swift/XRT of three relatively unexplored Supergiant Fast X-ray Transients (SFXTs), IGR J08408-4503, IGR J…
The 100-month Swift catalogue of supergiant fast X-ray transients I. BAT on-board and transient monitor flares
P. Romano, H. A. Krimm, D. M. Palmer +10
We investigate the characteristics of bright flares for a sample of supergiant fast X-ray transients and their relation to the orbital phase. We have retrieved all Swift/BAT Transi…
