Obscured Sources and Supergiant Fast X-ray Transients: New Classes of High Mass X-ray Binaries

Chaty, S.

A new type of high-energy binary systems has been revealed by the INTEGRAL satellite. These sources are in the course of being unveiled by means of multi-wavelength optical, near-and mid-infrared observations. Among these sources, two distinct classes are appearing: the first one is constituted of intrinsically obscured high-energy sources, of whi…

INTEGRAL and Swift Observations of Blazars in Outburst

Ghisellini, G.; Pian, E.; Foschini, L.

The blazars 3C 454.3, PKS 0537-441 and PKS 2155-304 are traditionally known to be among the most active sources of this class. They emit at all frequencies, up to gamma-rays, and are good probes of multiwavelength nuclear variability. The first two also have luminous broad emission line regions. We have recently monitored them with various facilit…

Soft Gamma Repeaters: New Results and Surprises from Swift, INTEGRAL, and the Interplanetary Network

Hurley, K.

The history and observational properties of the soft gamma repeaters are reviewed. Over the past decades, we have gone from viewing these objects as a special class of cosmic gamma-ray burst, to seeing them as one manifestation of magnetars. There is now a solid body of multi-wavelength observations, as well as some more controversial properties. …

New Results on Cataclysmic Variables Observed by INTEGRAL

Gális, R.; Hudec, R.; Šimon, V. +1 more

The results of investigations of cataclysmic variables and related objects with the ESA INTEGRAL satellite mostly within the Core Programme are presented and discussed. It is evident that the INTEGRAL satellite serves as an efficient tool to study some of these objects, especially those containing a magnetic white dwarf.

X-Ray and Optical Followup of Gamma-Ray (up to TeV) Sources

Masetti, N.

The imaging capabilities of the INTEGRAL and HESS observatories allow the study of hard X-ray and TeV sources with unprecedented positional accuracy. Here I review the multiwavelength followup studies which are currently being performed on the unidentified sources detected by these facilities in order to unveil their actual nature.

Microquasars: A Brief Overview and a Snapshot of GRS 1915+105 with INTEGRAL

Rodriguez, J.; Hannikainen, D. C.

Microquasars, sources of relativistic motion, have generated a lot of interest since their discovery. In this paper we shall briefly review some general properties of microquasars, and then focus on some recent observations of one of the more notorious microquasars, GRS 1915+105.
