Gamma-Ray Observatories are scientific facilities in space that detect and study high-energy gamma-ray emissions from celestial sources, providing valuable data on a wide range of astronomical phenomena such as Active Galactic Nuclei and blazars. AI generated definition based on: Advances in Space Res...
Here we report a multi-wavelength analysis, including publicly available James Webb Space Telescope data9 and our own Hubble Space Telescope data, for the same gamma-ray burst. We model its evolution up to two months after the burst and show that, at these late times, the recession of the...
The optical transmittance for a 3 mm thick crystal exceeded 65% when the wavelength was over 600 nm and exceeded 80% when over 1000 nm (Fig.1c). The high transmittance indicates that the as-grown single crystals do not have any significant concentration of optical absorption or scatter...
If you look in the datasheet of these diodes, the response curve as a function of wavelength is spiked in the 900 NM (infrared), while the energy of the particles E=hc/lambda corresponds to very small wavelengths. Need, in my humble opinion, Ultraviolet Responding Diodes, coupled with scin...
The quasi-simultaneous multi-wavelength emission of TeV blazar 3C 66A is studied by using a one-zone multi-component leptonic jet model. It is found that the quasi-simultaneous spectral energy distribution of 3C 66A can be well reproduced; in particular, the first three months of its average ...
Gamma radiation is in the form of electromagnetic rays, like X-rays or ultraviolet light, of a short (less than one-tenth of a nanometer), and thus energetic, wavelength. Gamma radiation is a physical means of sterilization or decontamination as the rays pass through the product being ...
ray light curves for these systems are shown in Fig.1, and the results of Monte Carlo simulations used to estimate their significance (see ‘Significance calibration via Monte Carlo simulations’ in the Methods) are shown in Fig.2. Of these, the eclipse in PSR J1555−2908 has the lowest...
crystal is NaI(Tl), i.e. sodium iodide doped with a trace of thallium. In this material, an energy-loss of 1 MeV will generate 38,000 photons in a narrow wavelength band centred on 415 nm. The sealed body33is needed, since NaI(Tl) material is very hygroscopic. In conventional ...
From the initial values before irradiation, the peaks shift by 5 to 6 nm, and the response times shorten by 140 to 440 ps. We attribute these observations to the radiation-induced defects on the bulk crystals. Our results nevertheless lead to the realization of short-wavelength ZnO ...
