Fermi-LAT has made a significant contribution to the study of high-energy gamma-ray diffuse emission and the observation of ~3000 discrete sources. However, one third of all gamma-ray sources (both galactic and extragalactic) are unidentified, the data on the diffuse gamma-ray emission should be clarified, and signatures of dark matter particles in the high-energy gamma-ray range are not...

The present status of scientific data acquisition system (SDAQ) developed by SRISA for the GAMMA-400 space telescope mission is presented. SDAQ provides the collection of the data from telescope detector subsystems (up to 100 GB per day), the preliminary processing of scientific information and its accumulation in mass memory, transferring the information from mass memory to the satellite...

Modifying a method of incident angle reconstruction for low-energy gamma rays in the GAMMA-400 gamma-ray telescope.
The GAMMA-400 gamma-ray telescope is designed to measure the gamma-ray fluxes in the energy range from 20 MeV to 1 TeV, performing a sensitive search in high-energy gamma-ray emission when annihilating or decaying dark matter particles. Such measurements also will concern the...

Timing large area plastic scintillation detectors are developing for the space gamma-ray telescopes now. For the in-flight calibration of these detectors the use of ultra-violet light-emitting diode, irradiating the 1 m long detector module at the center along its width is suggested. The results of the measurements show the possibility of this calibration system implementation.

The timing large area plastic scintillation detectors with silicon photomultipliers as photosensors properties were investigated using a cosmic radiation at the ground level. Different techniques of the amplitude spectra and efficiency measurements were implemented. The measurements results are presented also.

GAMMA-400 (Gamma Astronomical Multifunctional Modular Apparatus) parameters are optimized for detection of gamma-quanta with the energy $\sim~100$~GeV in the main aperture. Also there are opportunities to detect particles in additional and lateral apertures. Registered events identification procedures details are discussed in the presented article for gammas, electrons/positrons and protons...
