Details of the discovery of a new X-ray source, IGR J18462-0223, on October 12, 2007, during a short (several hours), intense (∼35 mCrab at the peak) outburst of hard radiation by the IBIS/ISGRI gamma-ray telescope onboard the INTEGRAL observatory are given. The detection of another earlier outburst from this source occurred on April 28, 2006, in the archival data of the telescope is reported. We present the results of the source’s localization and our spectral/timing analysis of the…

Outburst of the unknown source IGR J18175-2419 detected by the INTEGRAL observatory: Yet another fast X-ray transient?
The discovery of a new X-ray source, IGR J18175-2419, that flared up for a short (∼1 h) time on September 26, 2012, by the INTEGRAL observatory is reported. The results of the source’s localization…
IGR J16328?4726: A New Candidate Supergiant Fast X-ray Transient
The unidentified source IGR J16328−4726 was covered with INTEGRAL observations for a long period (∼9.8 Ms) and was undetectable for most of the time while showing a very recurrent micro-activity with…
High-mass X-ray binaries in the Milky Way
High-mass X-ray binaries are fundamental in the study of stellar evolution, nucleosynthesis, structure and evolution of galaxies and accretion processes. Hard X-rays observations by INTEGRAL and…

The first observation of AX J1749.1-2733 in a bright X-ray state—Another fast transient revealed by INTEGRAL
An intense outburst of hard radiation (with a peak flux of ∼50 mCrab) was detected from the X-ray transient AX J1749.1-2733 by the IBIS/ISGRI gamma-ray telescope onboard the INTEGRAL observatory when…
The Optical Counterpart to the Peculiar X-Ray Transient XTE J1739–302*
The weak X-ray transient XTE J1739-302, characterized by extremely short outbursts, has recently been identified with a reddened star. Here we present spectroscopy and photometry of the counterpart,…
IGR J08408-4503: a new recurrent supergiant fast X-ray transient
The supergiant fast X-ray transient IGR J08408-4503 was discovered by INTEGRAL on 2006 May 15 during a bright flare. The source shows sporadic recurrent short bright flares, reaching a peak…
IGR J18483–0311: a new intermediate supergiant fast X-ray transient
Context. IGR J18483−0311 is a high-mass X-ray binary recently discovered by INTEGRAL. Its periodic fast X-ray transient activity and its position in the Corbet diagram – although uncertain – led to…
XTE J1739–302 as a Supergiant Fast X-Ray Transient
XTE J1739-302 is a transient X-ray source with unusually short outbursts, lasting on the order of hours. Here we give a summary of X-ray observations we have made of this object in outburst with the…
INTEGRAL and Swift observations of the supergiant fast X-ray transient AX J1845.0-0433 = IGR J18450-0435
Context. AX J1845.0-0433 was discovered by ASCA in 1993 during fast outburst activity characterized by several flares on short timescales. Up to now, the source was not detected again by any X-ray…
Unveiling Supergiant Fast X-Ray Transient Sources with INTEGRAL
Supergiant high-mass X-ray binaries (SGXBs) are believed to be rare objects, as stars in the supergiant phase have a very short lifetime and to date only about a dozen of them have been discovered.…
