Rich Galaxy Clusters from CfA2 Redshift Survey: Spatial Dynamic and High-Energy Gamma-Emission
(2020) Khanh, L. N.; Arkhangelskaja, I. V.; Galper, A. M.; Dorosheva, D. N.; Архангельская, Ирина Владимировна
© 2020, Pleiades Publishing, Ltd.Abstract: Preliminary results of the investigation of the characteristics of 5 groups of galaxies are discussed in the presented article. We have analyzed the main characteristics of galaxy clusters 933, 88, 142, 1046, 1101 from CfA2 redshift survey. Clusters 933, 142, 1046, and 1652 have high-energy gamma associations on Fermi/LAT data (4FGL J1144.9 + 1937, 4FGL J0152.2 + 3714, 4FGL J1230.8 + 1223 and 4FGL J1653.8 + 3945). These sources are active galaxies. Furthermore, the radiogalaxy 3C 264 (4FGL J1144.9 + 1937) was previously observed in the energy band E>1 TeV. We have found several anomalies of the spatial dynamics of galaxies in these clusters. These features could be caused by the dynamics of galaxies’ motion in a gravitationally bound group taking into account possible space–time inhomogeneities at large distances. Investigation of high-energy gamma-emission of galaxies and peculiarities of its motion in groups allows studying properties of such inhomogeneities and understanding of its nature possibly caused by dark matter. The investigation of the spatial distribution and other characteristics of 933, 88, 142, 1046, 1101 galaxy clusters shows gravitational lensing effect. But now it is unknown which objects are gravitational lenses for these clusters. The angular size of such clusters is about 1–2 degree and now there are not clear associations between group members of clusters 142, 1046, and 1652 with the high-energy gamma-sources 4FGL J0152.2 + 3714, 4FGL J1230.8 + 1223, and 4FGL J1653.8 + 3945. Common observations of such clusters by orbital gamma-ray observatories with high angular resolution and ground-based Cherenkov air-shower experiments could possibly clarify the type of gravitational lenses.

© 2020, Pleiades Publishing, Ltd.Abstract: The GAMMA-400 gamma-ray telescope is planned for the launch at the end of 2026 on the Navigator service platform designed by Lavochkin Association on an elliptical orbit with following initial parameters: an apogee ̴300 000, a perigee ̴500 km, a rotation period ̴7 days and inclination of 51.4̊. The apparatus is expected to operate for more than 5 years, reaching an unprecedented sensitivity for the search of dark matter signatures and the study of the unresolved and so far unidentified gamma-ray sources. The segmented anticoincidence counters surround the converter-tracker and calorimeter of the telescope with the purpose of vetoing to assure a clean track reconstruction and charged particle background suppression. The anticoincidence detector prototype based on long BC-408 scintillator with silicon photomultipliers readout was tested using 300-MeV positron beam of synchrotron C-25P ‘‘PAKHRA’’ of Lebedev Physical Institute. The measurement setup, design concepts for the prototype detector together with test results are discussed.

© 2019, Allerton Press, Inc.Abstract: The future space-based γ-ray telescope GAMMA-400 will be installed on the Navigator platform of the Russian astrophysical observatory. A highly elliptical orbit will allow prolonged (~100 days) continuous observations of many regions of the celestial sphere for 7–10 years. GAMMA-400 will measure fluxes of γ‑ray emission in the energy range of ~20 MeV to several TeV and electrons + positrons to ~20 TeV. The γ-ray telescope will have excellent separation of γ-ray emissions against the background of cosmic rays and electrons + positrons from protons, along with unprecedented angular (~0.01° at Eγ = 100 GeV) and energy (~1% at Eγ = 100 GeV) resolutions 5–10 times better than for the Fermi-LAT and ground-based γ-ray telescopes. GAMMA-400 observations will provide fundamentally new data on discrete sources and spectra of γ-ray emissions and electrons + positrons.

© 2019, Allerton Press, Inc.Abstract: The GAMMA-400 space project is one of the new generation of space observatories designed to search for signs of dark matter in the cosmic gamma emission, and to measure the characteristics of diffuse gamma-ray emission and gamma-rays from the Sun during periods of solar activity; gamma-ray bursts; extended and point gamma-ray sources; and electron, positron, and cosmic-ray nuclei fluxes with energies in the TeV ranges. The GAMMA-400 γ-ray telescope constitutes the core of the scientific instrumentation. The nature of the intended experiments imposes stringent requirements on the gamma telescope’s system of trigger signal formation, now being developed using the state-of-the-art logic devices and fast data links. The design concept of the system is discussed, along with the chosen engineering solutions and some experimental results obtained during the operation of the system prototype using a positron beam with energies of 100–300 MeV from the PAKHRA S-25R synchrotron at the Lebedev Physical Institute.

Gammas and Charged Particles Identification in Lateral and Additional Apertures of GAMMA-400
(2019) Bakaldin, A. V.; Dalkarov, O. D.; Egorov, A. E.; Gusakov, Y. V.; Arkhangelskaja, I. V.; Arkhangelskiy, A. I.; Galper, A. M.; Chernysheva, I. V.; Chasovikov, E. N.; Kheymits, M. D.; Leonov, A.

© 2019, Pleiades Publishing, Ltd.The GAMMA-400 (Gamma Astronomical Multifunctional Modular Apparatus) will be a new generation satellite gamma-observatory. The gamma-ray telescope GAMMA-400 consists of the anticoincidence system (top and lateral sections—ACtop and AClat), the converter-tracker (C), the time-of-flight system TOF (two sections S1 and S2), the position-sensitive and electromagnetic calorimeters (CC1 and CC2), the scintillation detectors of the calorimeter (S3 and S4) and lateral anticoincidence detectors of the calorimeter LD. Two apertures used for observation of transient events do not require the best angular resolution as for the gamma-ray bursts and solar flares from both upper and lateral directions. Additional aperture allows the particle registering from upper direction, which do not interact with converter-tracker and do not form a TOF signal. The lateral aperture allows registering of γ-quanta in perpendicular direction with respect to main axis of GAMMA-400 due to CC2, LD, S3, and S4. The thickness of CC2 in this direction is ∼44 X0 and this allows detection of gammas, electrons and positrons with energies up to 10 TeV. The results of calculation of the fractal dimension of temporal profiles of additional aperture prototype of GAMMA-400 during its calibration using secondary positron beam of the synchrotron C-25P “PAKHRA” of Lebedev Physical Institute confirm the absence of any correlation between the AC and CC1 characteristics and correspondence of additional aperture background to Poisson statistics or Erlang one with shape parameter up to 10.

© 2021, Pleiades Publishing, Ltd.Abstract: The future space-based GAMMA-400 γ-ray telescope will operate onboard the Russian astrophysical observatory in a highly elliptic orbit during 7 years. Observing γ-ray sources from Galactic plane, γ-ray bursts, γ-ray diffuse emission, γ rays from the Sun, and γ rays from dark matter particles will be performed uninterruptedly for a long time (∼100 days) in point-source mode in contrast to scanning mode for Fermi-LAT and other space- and ground-based instruments. GAMMA-400 will measure γ rays in the energy range from ∼20 MeV to several TeV units, have the unprecedented angular (∼0.01° at Eγ = 100 GeV) and energy (∼2% at Eγ =100 GeV) resolutions better than for Fermi-LAT, as well as ground-based γ-ray facilities, by a factor of 5–10, and perfectly separate γ rays from cosmic-ray background.

Capabilities of the GAMMA-400 gamma-ray telescope to detect gamma-ray bursts from lateral directions
(2022) Topchiev, N. P.; Bakaldin, A. V.; Dalkarov, O. D.; Egorov, A. E.; Leonov, A. A.; Galper, A. M.; Arkhangelskaja, I. V.; Arkhangelskiy, A. I.; Chernysheva, I. V.; Kheymits, M. D.; Korotkov, M.

© 2021 COSPARThe currently developing space-based gamma-ray telescope GAMMA-400 will measure the gamma-ray and electron + positron fluxes using the main top-down aperture in the energy range from ∼ 20 MeV to several TeV in a highly elliptic orbit (without shading the telescope by the Earth and outside the radiation belts) continuously for a long time. The instrument will provide fundamentally new data on discrete gamma-ray sources, gamma-ray bursts (GRBs), sources and propagation of Galactic cosmic rays and signatures of dark matter due to its unique angular and energy resolutions in the wide energy range. The gamma-ray telescope consists of the anticoincidence system (AC), the converter-tracker (C), the time-of-flight system (S1 and S2), the position-sensitive and electromagnetic calorimeters (CC1 and CC2), scintillation detectors (S3 and S4) located above and behind the CC2 calorimeter and lateral detectors (LD) located around the CC2 calorimeter. In this paper, the capabilities of the GAMMA-400 gamma-ray telescope to measure fluxes of GRBs from lateral directions of CC2 are analyzed using Monte-Carlo simulations. The analysis is based on off-line second-level trigger construction using signals from S3, CC2, S4 and LD detectors. For checking the numerical algorithm the data from space-based GBM and LAT instruments of the Fermi experiment are used, namely, three long bursts: GRB 080916C, GRB 090902B, GRB 090926A and one short burst GRB 090510A. The obtained results allow us to conclude that from lateral directions the GAMMA-400 space-based gamma-ray telescope will reliably measure the spectra of bright GRBs in the energy range from ∼ 10 to ∼ 100 MeV with the on-axis effective area of about 0.13 m2 for each of the four sides of CC2 and total field of view of about 6 sr.

© 2022 COSPARThe future space-based GAMMA-400 gamma-ray telescope will operate onboard the Russian astrophysical observatory in a highly elliptic orbit during 7 years to observe Galactic plane, Galactic Center, Fermi Bubbles, Crab, Vela, Cygnus X, Geminga, Sun, and other regions and measure gamma- and cosmic-ray fluxes. Observations will be performed in the point-source mode continuously for a long time (∼100 days). GAMMA-400 will measure gamma rays in the energy range from ∼ 20 MeV to several TeV and cosmic-ray electrons + positrons up to several tens TeV. GAMMA-400 instrument will have very good angle and energy resolutions, high separation efficiency of gamma rays from cosmic-ray background, as well as electrons + positrons from protons. The main feature of GAMMA-400 is the unprecedented angular resolution for energies > 30 GeV better than the space-based and ground-based gamma-ray telescopes by a factor of 5–10. GAMMA-400 observations will permit to resolve gamma rays from annihilation or decay of dark matter particles, identify many discrete sources, clarify the structure of extended sources, specify the data on cosmic-ray electron + positron spectra.
