8. Tunka-133: Results of 3 Year Operation.

Prof. Vasily Prosin (Skobeltsyn Institute of Nuclear Physics of Lomonosov Moscow State University)

24/05/2013, 09:00

The improved methods of EAS parameters reconstruction in Tunka-133 suitable both for the internal and external shower core position are described. The methods are used for the analysis of data collected during three winter seasons from 2009 till 2012. The primary CR energy spectrum in the range 10^15 – 10^18 eV is presented. The variation of X_max distribution parameters with energy and...

44. Tunka-Rex: Status and Results of the First Measurements

Mr Dmitriy Kostunin (Karlsruhe Intitute of Technology, Germany)

24/05/2013, 09:20

Tunka-Rex is the new radio extension to Tunka-133 located in Siberia close to lake Baikal. The latter is a photomultiplier array registering air-Cherenkov light from air showers induced by cosmic-ray particles with initial energies of ${10}^{1}6$ – ${10}^{1}8$ eV. Tunka-Rex extends this detector with 20 antennas spread over an area of 1 km2 . It is triggered externally by Tunka-133, and detects the...

68. TeV Astrophysics with the HAWC Gamma-Ray Observatory

Dr Gus Sinnis (Los Alamos National Laboratory)

24/05/2013, 09:40

The High Altitude Water Cherenkov (HAWC) Observatory is a wide-field gamma-ray detector sensitive to gamma rays with energies between 100 GeV and 100 TeV.  Located on the volcán Sierra Negra in Puebla, Mexico at an elevation of 4100 meters above sea level, HAWC will observe ~6 sr of the sky each day.  The large field-of-view and continuous operation make HAWC an ideal instrument to search the...

75. Status of LHAASO and Updates on the ARGO-YBJ Observations

CAO ZHEN

24/05/2013, 10:00

In this presentation, the status of the LHAASO is updated mainly about the site preparation and proposing of the project, together with some results using the prototype detectors. As the phase-0, the LAWCA project is going to be covered by the report, including its proposing status. Some progress on ARGO-YBJ analysis is updated as well.

86. Fundamental physics with present and future Cherenkov telescopes

Alessandro De Angelis (UD)

24/05/2013, 10:20

Cherenkov telescopes can open a new light on several aspects of fundamental physics, providing information complementary to accelerators. In this talk I concentrate on the implications of the characteristics of photon propagation on the existence of light particles coupling to photons, and to possible new physics beyond relativity.

77. Indirect Search for Dark Matter with Cherenkov Telescopes

Michele Doro (PD)

24/05/2013, 10:40

In the general WIMP scenario, dark matter (DM) can be seen in gamma-rays because photons can found in various DM annihilation or decay processes, either as broad-band or line emission or because of secondary processes of charged particles in the final stages of annihilations or decays. The energy range of the former processes is accessible by current ground-based Imaging Atmospheric Cherenkov...
