Aims. We present X-ray and 12 CO(J=1–0) observations of the very-high-energy (VHE) γ-ray source HESS J1813–178 with the aim of understanding the origin of the γ-ray emission. Methods. High-angular resolution X-ray studies of the VHE γ-ray emission region are performed using 18.6 ks of XMM-Newton data, taken on HESS J1813–178 in October 2005. Using this… (More)
The observation of slow-wave sustained (SW) discharge in a whistler- or helicon-wave range of frequency is made using high-frequency and very-high-frequency bands of rf. The SW discharge occurs at an extremely low rf power and plasma density, which are lower than a capacitive-coupling discharge region.
The second survey of the molecular clouds in 12 CO (J = 1–0) was carried out in the Large Magellanic Cloud by NANTEN. The sensitivity of this survey is twice as high as that of the previous NANTEN survey, leading to a detection of molecular clouds with M CO 2 × 10 4 M ⊙. We identified 272 molecular clouds, 230 of which are detected at three or more observed… (More)
We investigate the local correlation betwen the 1.4 GHz radio continuum and 60 µm far-infrared (FIR) emission within the Large Magellanic Cloud (LMC) on spatial scales between 0.05 and 1.5 kpc. On scales below ∼1 kpc, the radio-FIR correlation is clearly better than the correlation of the cold gas tracers with either the radio or the FIR emission. For the… (More)
Lead-free KNbO<sub>3</sub> ceramics were synthesized from alkoxy-derived powders fabricated by sol-gel process. The powders size-controlled from about 200 to 400 nm by different solvents and calcination temperatures were formed to ceramic discs by an ordinary ceramics processing, then sintered at 1020degC in K<sub>2</sub>O-rich atmosphere. Single phase… (More)
