Kinky particles: the GRAPES-3 experiment in Ooty, India depicted with a simulated cosmic ray shower. The inset shows the cosmic ray proton spectrum measurement by GRAPES-3 along with observations by ...
The GRAPES-3 experiment in Ooty, India, operated by the Tata Institute of Fundamental Research has discovered a new feature in the cosmic-ray proton spectrum at about 166 tera-electron-volt (TeV) ...
An international team of researchers extended their results from a previous study to directly measure the cosmic-ray all-electron (electron + positron) spectrum in an energy range from 11 GeV to 4.8 ...
Long-term study The HESS observatory in Namibia has made a “unique measurement” of the electron and positron cosmic ray spectrum. (Courtesy: Klepser/DESY/HESS collaboration/CC BY-SA 3.0) A new ...
Astronomers have worked out the colour of the Universe — and it's a shade between aquamarine and a pale turquoise. This is the colour resulting from a 'census' of light from 166,000 galaxies, captured ...
THE shape of the spectrum of cosmic ray electrons in the 100 GeV range and beyond can provide information about a variety of problems in cosmic ray astrophysics. The differential energy spectrum ...
