  2. 4. TeV Gamma-Ray Observations with Milagro
    Gus Sinnis (Los Alamos National Laboratory, USA)

    In this paper I will report on the analysis of data taken with the Milagro Observatory within 10 degrees of the Galactic plane between Galactic longitude 30 and 220 degrees. Three new sources of TeV gamma rays have been discovered, all of which are coincident with sources in the EGRET GeV catalog. In addition, there are 5 locations, that warrant further study. In particular, there is a 5...

  3. 54. ARGO-YBJ experiment in Tibet
    Giacomo D'ali' Staiti (University of Palermo)

    The setting-up of the ARGO detector at the YangBaJing Cosmic Ray Laboratory (4300 m a.s.l., Tibet, P.R. China) has been completed during the last spring (2007). It consists of a central carpet made of 130 identical sub-units of 12 RPCs each ('cluster') covering a surface of about 5800 m**2 with 93% active area, and a guard ring of 24 further clusters of the same type surrounding the central...

  4. 1. Gamma-ray astronomy: Recent results from the H.E.S.S. telescope system
    Gerd Puehlhofer (ZAH Landessternwarte, Heidelberg, Germany)
    20/06/2007, 15:35
    One of the promises of VHE gamma-ray astronomy has been to shed light on the acceleration sites of cosmic rays. The H.E.S.S. array of imaging Cherenkov telescopes has indeed revealed a large number of new VHE gamma-ray emitters, particularly in the Milky Way, but also outside our Galaxy. The talk aims to provide an overview of the different types of objects discovered. To unravel their...

  5. 2. Highlights of MAGIC results
    Denis Bastieri (Università & INFN Padova, Italy)
    20/06/2007, 16:00
    MAGIC is the largest Cherenkov telescope currently operating and is in full operation since September 2004. Since then, it is providing a full wealth of exciting new physics results from its observations in the VHE region of galactic and extragalactic locations. Among the main results that will be presented, the discoveries of new sources and even of entire new classes of sources and the...

  6. 3. First Results from the VERITAS Gamma-ray Telescopes
    David Hanna (McGill University, Canada)
    20/06/2007, 16:25
    VERITAS is an array of four 12m diameter Cherenkov telescopes, designed to explore the very high energy gamma-ray sky in the energy band between 100 GeV and 50 TeV. Its construction and commissioning have occured over the past two years and the array has been taking scientific data with three or more telescopes since November 2006. We will present results from observations made with VERITAS...
