GAMMA-RAY DATA [8 records]

Record 1 2025-02-04

English

Subject field(s)
  • Astronautics
  • Satellite Telecommunications
  • Collaboration with WIPO
CONT

We examine a sample of 2301 gamma-ray bursts, detected by Konus-Wind in the triggered mode between 1994 and 2017 and localized by the interplanetary network(IPN), for evidence of gravitational lensing. We utilize all the available gamma-ray burst(GRB) data : time histories, localizations, and energy spectra. We employ common IPN techniques to find and quantify similarities in the light curves of 2, 646, 150 burst pairs, and for the pairs with significant similarities, we examine their IPN localizations to determine whether they are consistent with a common origin.

Les Français ont fourni des instruments composés de détecteurs gamma à scintillation aux Russes qui s'occupaient quant à eux de la plateforme 1 du satellite. En 1977, fut lancé l'instrument Signe 2 à bord de la mission russe Prognoz 6, en orbite autour de la Terre. Par la suite, le même instrument fut lancé à bord de deux satellites jumeaux appelés Prognoz 7, constituant deux membres du réseau interplanétaire.

Like optical LANDSAT and/or multi-beam radar data, gamma-ray channels(bands) can be displayed as ternary colour composite images... allowing for the interpretation of three channels of elemental or ratio data using an additive mix of the primary colours(red-green-blue) of the computer display system.

Subject field(s)
  • Scientific Instruments

  • Remote Sensing
  • Cartography
DEF

An instrument for determining the energy distribution of gamma rays.

CONT

Gamma rays are electromagnetic radiation at the short-wavelength, or high-frequency, end of the electromagnetic(EM) spectrum, which ranges from gamma rays(short) to radio(long). The study and analysis of gamma-ray spectra for scientific and technical use is called gamma spectroscopy, and gamma-ray spectrometers are the instruments which observe and collect such data. Because the energy of each photon of EM radiation is proportional to its frequency, gamma rays have sufficient energy that they are typically observed by counting individual photons.

OBS

The gamma-ray spectrometer is used for detecting iron, magnesium titanium, thorium and potassium. It is also used for identifying samples of unknown composition.

OBS

gamma ray spectrometer: term standardized by the International Electrotechnical Commission (IEC).

Appareil qui permet de déterminer le spectre d'énergie des rayons gamma.

CONT

Les spectromètres à rayons gamma actuels permettent de donner une analyse précise [...] et rapide de la concentration en uranium, thorium et potassium dans les roches ou les sols. [...] Les spectromètres à rayons gamma fonctionnent sur le même principe que le scintillomètre à l'exception qu'ils utilisent les caractéristiques relatives à l'intensité ou l'énergie spécifique des rayons gamma des isotopes radioactifs.

CONT

BATSE was a high energy astrophysics experiment in orbit around Earth on NASA's Compton Gamma-Ray Observatory. The primary objective of BATSE was to study the phenomenon of gamma-ray bursts, although the detectors also recorded data from pulsars, terrestrial gamma-ray flashes, soft gamma repeaters, black holes, and other exotic astrophysical objects.
