INTEGRAL, ESA’s next venture in gamma-ray astronomy is due for launch in 2001. In addition to the two large gamma-ray instruments INTEGRAL will carry an X-ray monitor, JEM-X, and an optical monitor, OMC. The primary role of JEM-X will be to provide data on the X-ray flux and its variations from the targets observed by the gamma-ray instruments. JEM-X will also provide accurate positions for transient X- and gamma-ray sources observed during the mission. Together with the optical monitor, JEM-X can carry out a special program on stellar activity, independent of the two high energy instruments on INTEGRAL. © 2000 American Institute of Physics.

    We present an analysis of Chandra ACIS observations of the field of TeV J2032+4130, the first unidentified TeV source, detected serendipitously by HEGRA. This deep (48.7 ks) observation of the field follows up on an earlier 5 ks Chandra director’s discretionary observation. Of the...

    Gamma-ray binary systems are still a sparsely populated source class. Although the individual gamma-ray binaries share some common features, it is not possible to explain their emission mechanisms in a common framework yet. We present the highlights from our MAGIC observations of the best...

    We present the analysis results of Suzaku observation of the unidentified very high energy (VHE) gamma-ray source, HESS J1427-608. In the XIS image, we found an extended source (referred as "Suzaku source"), which is positionally coincident with HESS J1427-608. In order to estimate the flux...

    All-sky observations from hard X-ray to soft gamma-ray band is very important to study non-thermal processes for many bright astronomical objects such as Gamma-ray Bursts (GRBs), soft gamma-ray repeaters (SGRs), and solar flares. The Wide-band All-sky Monitor (WAM) onboard Suzaku enables unique...

    We present a summary of γ-ray and X-ray observations of the intriguing COS-B field, 2CG 075+00, in order to search for potential counterparts. The third EGRET (3EG) catalog shows that the COS-B emission corresponds to at least two localized γ-ray sources, 3EG 2016+3657 and 3EG J2021+3716....
