Using public Fermi Large Area Telescope (LAT) and Swift Burst Alert Telescope observations, we constructed the first sample of blazars selected at both hard X-rays and gamma rays. Studying its spectral properties, we find a luminosity dependence of t

We present the results of a study with the \emph{Swift} Burst Alert Telescope in the 14 -- 195 keV range of the long-term variability of 5 low mass X-ray binaries with reported or suspected super-orbital periods -- 4U 1636-536, 4U 1820-303, 4U 1916-0

We report the first measurements of the 511 keV line emission from the Galactic Centre (GC) region performed with the spectrometer SPI on the space observatory INTEGRAL (International Gamma-Ray Astrophysics Laboratory). Taking into account the range

We present the observations of the X-ray burster KS 1731-260 from 1988 until 1999 with the Kvant/TTM telescope supplemented with published data from the ASM and PCA instruments of the RXTE observatory for 1996–2001. We constructed the light curve o

The CLAIRE collaboration is presently preparing the first astronomical observation of a gamma-ray lens. In June 2000, the instrument is to be flown on a stratospheric balloon by the French Space Agency CNES. CLAIRE features a Laue diffraction lens, a

We provide an overview of positron astronomy results that have been obtained using the INTEGRAL spectrometer SPI, and discuss their implications for the still mysterious origin of positrons in our Galaxy. It has long been known that the 511 keV posit

The use of germanium detectors for gamma-ray astronomy from space has so far been restricted to single detectors providing no spatial information. We describe here the development of an array detector with up to sixteen independent germanium elements

Three bright X-ray transient sources GRO J0422+32, GRS 1009-45 and GRS 1716-24 detected in 1992–1993 continue the sequence of such transient sources which were observed by the broad-band MIR-KVANT X-ray observatory in the period since 1988. Two of

A new method is proposed for reconstructing the data from coded aperture X/γ -ray telescopes. This technique, based on the Wiener criterion, is essentially a generalisation of existing Wiener filtering methods but is not confined to systems with pos
