GRAPES-3—A high-density air shower array for studies on the structure in the cosmic-ray energy spectrum near the knee
Abstract The change in the spectral index from about - 2.7 to - 3.1 at ∼ 3 × 10 15  eV in the all-particle energy spectrum of primary cosmic rays is very significant for learning about the nature ofExpand

A large area muon tracking detector for ultra-high energy cosmic ray astrophysics: The GRAPES-3 experiment
Abstract Certain aspects of ultra-high energy (UHE) cosmic ray astrophysics require correlated studies on the electron and muon components of air showers, namely, the search for cosmic ray sourcesExpand

Energy spectrum of diffuse component of cosmic soft γ rays
IN this paper we present new measurements on the diffuse component of cosmic soft gamma rays in the energy range 0.1–4 MeV obtained with a balloon-borne telescope. These measurements show that theExpand

Quiescent state X-ray emission from flare stars.
Quiescent-state X-ray emission of seven flare stars was studied as well as the relationship between the emissions of the chromosphere, transition region and corona. These X-ray emissionExpand

A search for ultra high-energy γ-ray bursts from celestial sources
We report here the details of an experiment carried out at mountain altitude, at Ootacamund (2.2 km above sea level), India between March 1977 and March 1979, to detect bursts of high energy (∼ 5 ×Expand
