The public data from the EGRET space telescope on diffuse Galactic gamma rays in energy range 0.1 to 10 GeV are reanalyzed with purpose of searching for signals Dark Matter annihilation (DMA). analysis confirms previously observed excess energies above 1 comparison expectations conventional models. In addition, was found show all key features a signal Annihilation (DMA): a) is observable sky directions and has same shape everywhere, thus pointing common source; b) corresponds expected...
The work contained herein constitutes a report of the ``Beyond Standard Model'' working group for Workshop "Physics at TeV Colliders", Les Houches, France, 26 May--6 June, 2003. research presented is original, and was performed specifically workshop. Tools calculations in minimal supersymmetric standard model are presented, including comparison dark matter relic density predicted by public codes. Reconstruction particle masses LHC future linear collider facility examined. Less orthodox...
Monitoring radiation background in the near-surface atmosphere and gamma rays, geoacoustic emission, temperature a borehole at 40 m depth, as well Doppler sounding on low-inclined radio pass, proceeded Tien Shan mountain station (3340 a.s.l.) northern with common goal of searching for seismogenic effects preceding earthquakes. The flux rays varied negligibly between days, it was not influenced by precipitation. Characteristic bay-like drops ray were found (2–8) days before M5.0–M6.2 In an...
During the catastrophic M7.8 earthquake in Turkey on 6 February 2023, anomalous effects were revealed ionosphere associated with various propagation mechanisms of seismogenic disturbance from lithosphere up to height ionosphere. Seventeen minutes after main shock, a co-seismic was detected by Doppler ionosonde an inclined, 3010 km long, two-hop radio path “Kuwait—Institute Ionosphere (Almaty)”. An appearance acoustic waves at 232 fixed 568 s arrival surface Rayleigh wave sub-ionospheric...
After the explosive eruption of Hunga Tonga volcano on 15 January 2022, disturbances were observed at a distance about 12,000 km in Northern Tien Shan and regarded variations atmospheric pressure, telluric current, Doppler frequency shift ionospheric signal. At 16:00:55 UTC, pulse pressure was detected there, with peak amplitude 1.3 hPa propagation speed 0.3056 km/s, equal to velocity Lamb waves. In shift, two types registered 3212 2969 long inclined radio paths, one which arose as response...
The second-stage neutrino telescope BAIKAL-GVD in Lake Baikal will be a research infrastructure aimed mainly at studying astrophysical fluxes by recording the Cherenkov radiation of secondary muons and showers generated interactions. prototyping/early construction phase project which is directed towards deployment operation first demonstration cluster has been started April 2011. An important step on realization GVD was made 2014 second stage contains 112 OMs arranged five strings, as well...
The article describes in detail the equipment and method for measuring Doppler frequency shift (DFS) on an inclined radio path, based principle of phase-locked loop using SDR receiver investigation seismogenic man-made disturbances ionosphere. During two M7.8 earthquakes Nepal (25 April 2015) Turkey (6 February 2023), a ionosonde detected co-seismic pre-seismic effects ionosphere, appearances which are connected with various propagation mechanisms disturbance from lithosphere up to One day...
New results from the Baikal neutrino telescope NT200, based on first 5 years of operation (1998–2003), are presented. We derive an all-flavor limit diffuse flux astrophysical neutrinos between 20 TeV and 50 PeV, extract enlarged sample high energy muon events, obtain limits atmospheric muons. In 2005, upgraded NT200+ will be commissioned: 3 additional distant strings with only 12 photo-multipliers each rise effective volume to Mton at 10 PeV for this largest running in Northern hemisphere.
Two new observations have strengthened the case for supersymmetric nature of Cold Dark Matter component in our universe: First, it was shown that data on nuclear abundance, B/C - and 10Be/9Be ratios constrain diffusion parameters Galactic Models so strongly, they lead to a clear deficiency production diffuse hard gamma rays, antiprotons positrons, if no anomalous sources or energy dependence coefficients are postulated. Second, from precise relic density measurement by WMAP WIMP annihilation...
Phenomena have been observed in mountain high-energy cosmic-ray experiments, namely, a delayed absorption of cascades initiated by hadrons lead absorber at E0≳ 1014 eV (so-called long-flying component), coplanarity most energetic particles the central region γ-ray−hadron superfamilies, and so-called Tien Shan effect EAS cores 1016 s>5 TeV. These effects are not described theoretical models. The is explained process coplanar generation secondary interactions superhigh-energy with nuclei...
