Protons with energies up to approximately 10(15) eV are the main component of cosmic rays, but evidence for the specific locations where they could have been accelerated to these energies has been lacking. Electrons are known to be accelerated to cosmic-ray energies in supernova remnants, and the shock waves associated with such remnants, when they hit the(More)
Reconstruction of the continuity of the orbicularis oris is the main component in correction of the whistling deformity. However, many of the cases are associated with other deformities, such as conspicuous lip scars, an unnaturally wide central lip, flaring alae with wide nostril floors, and a short columella with a flat nasal tip. We report a technique(More)
We report on the status of the construction of an array of four 10 m atmospheric Cherenkov telescopes for gamma-ray astronomy, near Woomera, in South Australia – the CANGAROO-III project. The first telescope of this array is the upgraded version of the CANGAROO-II 7 m telescope and has been in operation since March 2000. The second telescope, an improved(More)
We present an analysis of the data from our Swedish-ESO Submillimetre Telescope molecular line survey in the 1.3 mm band of the N, M, and NW positions in the Sgr B2 molecular cloud. The line emissions from 42 molecular species, and some of their isotopomers, were analyzed assuming a single temperature and a homogeneous source. In cases where a source size(More)
CANGAROO-III is an array of four 10m-diameter imaging atmospheric Cherenkov telescopes to search for sub-TeV gamma-rays from celestial objects in collaboration with Japanese and Australian institutions, which is located in southern hemisphere (Woomera, South Australia). Three of four telescopes were made with the same design for stereo observation. We have(More)
We have detected gamma-ray emission at the 6 σ level at energies greater than 500 GeV from the supernova remnant RX J0852.0−4622 (G266.2−1.2) using the – 2 – CANGAROO-II Imaging Atmospheric Cherenkov Telescope (IACT). The flux was 0.12 times of that of Crab at 1 TeV. The signal centroid is consistent with the peak of the X-ray emission in the northwest rim(More)
A preliminary result from Markarian 421 observations in the energy region above 10 TeV with the CANGAROO-II 10 m telescope is presented. In January 2001, the HEGRA group reported that Markarian 421 had become very active, with flux levels up to 4 times that of the Crab Nebula. As a result, we observed Mkn 421 during six nights from Jan-uary 24th to February(More)
We report the development of the data acquisition system of the CANGAROO-III imaging Cherenkov telescope. Multi-pixel cameras consisting of 552 and 427 PMTs are placed at the prime focus of the first and second telescopes respectively. The charge and hit timings of each PMT are measured with ADCs and TDCs respectively via a fast VME-bus which is selected to(More)
